The Short Answer: Yes, But Medicare Part B Has to Approve It First

Medicare supplement plans do cover orthotics and prosthetics — and for most people with a good Medigap plan, they’ll cover most or all of what Medicare Part B doesn’t pay. But the coverage chain here matters a lot, and if you skip a step or work with the wrong supplier, you could end up on the hook for thousands of dollars out of pocket.

Here’s how it actually works. Medicare Part B covers orthotics and prosthetics as durable medical equipment (DME) when your doctor deems them medically necessary. Part B pays 80% of the Medicare-approved amount after you’ve met the 2026 Part B deductible, which is $257. Your Medigap plan then steps in to cover some or all of that remaining 20%, depending on which plan letter you have.

So if you’re asking whether you need a Medigap plan to protect yourself from prosthetic costs — the answer is almost always yes. A high-end prosthetic limb can cost $15,000 to $70,000 or more. Twenty percent of that is real money.

What Medicare Part B Actually Covers (And What It Doesn’t)

Before your Medigap plan can do anything, Part B has to say the device is covered. Medicare defines orthotics and prosthetics under its DME benefit, and the coverage is actually reasonably broad. But there are firm rules.

Part B covers:

• Prosthetic limbs (arms, legs, partial foot prosthetics)
• Ocular prostheses (artificial eyes)
• Orthotic devices like braces for the back, neck, knee, ankle, and wrist when prescribed by a doctor
• Replacement of prosthetics when there’s a medical reason (wear, change in condition)
• Repairs to covered prosthetics

Part B does not cover:

• Orthopedic shoes (with one narrow exception for people with severe diabetic foot disease)
• Supportive devices for feet in most circumstances
• Devices that aren’t prescribed by a physician
• Items purchased from a supplier who isn’t enrolled in Medicare

That last point trips people up constantly. I’ve seen it happen where someone buys a perfectly good brace or orthotic insert from a medical supply store, submits for reimbursement, and gets denied because the supplier wasn’t a Medicare-enrolled DME supplier. Always confirm your supplier is enrolled before you buy anything.

How Different Medigap Plans Handle the 20% Gap

This is where your plan letter makes a real difference. Not all Medigap plans cover the same share of the Part B coinsurance, so let’s be specific.

Medigap Plan	Part B Deductible ($257 in 2026)	Part B Coinsurance (20%)	Your Out-of-Pocket for Orthotics/Prosthetics
Plan G	Not covered	100% covered	$257 per year, then $0
Plan N	Not covered	Covered (some copays may apply)	$257 per year, then usually $0
Plan F (pre-2020 enrollees only)	100% covered	100% covered	$0
Plan K	Not covered	50% covered	$257 plus 10% of approved amount
Plan L	Not covered	75% covered	$257 plus 5% of approved amount

If you have Plan G, which is the most popular Medigap plan sold today and typically costs between $100 and $200 per month for a 65-year-old depending on your state and insurer, you’re in a good position. Once you’ve paid that $257 Part B deductible for the year (2026 figure), your Plan G covers the full 20% coinsurance. On a $30,000 prosthetic leg, that’s $6,000 in coinsurance that your Medigap plan absorbs completely.

Plan K and Plan L are the ones I’d be most cautious about if you have significant prosthetic or orthotic needs. They were designed to have lower premiums with more cost-sharing, which is fine if you’re healthy. But if you need a prosthetic limb, they leave you holding part of that coinsurance, and it can add up fast.

The Biggest Mistake People Make With Prosthetics and Medicare

In my experience, the single most costly mistake is going out of network with a DME supplier and not realizing until the bill arrives.

Here’s the thing. Medicare has what’s called a “participating supplier” system for DME. Suppliers can either accept assignment (meaning they agree to bill only the Medicare-approved amount) or they can charge more than the approved amount. If your supplier doesn’t accept assignment, they can charge up to 15% above what Medicare approves. That 15% excess charge is called the limiting charge, and most Medigap plans do not cover it. Plan G doesn’t cover excess charges. Plan N doesn’t either.

The only standard Medigap plans that cover Part B excess charges are Plan F (no longer available to new Medicare enrollees as of 2020) and Plan G High Deductible.

So if you have Plan G and your prosthetic supplier doesn’t accept Medicare assignment, you could be responsible for up to 15% of the approved amount on top of everything else. On a $40,000 prosthetic, the Medicare-approved amount might be $25,000, and 15% of that is $3,750 coming out of your pocket.

Always ask your DME supplier before any purchase: “Do you accept Medicare assignment?” If they don’t, find one who does. This one question can save you thousands.

Special Situations Worth Knowing About

A few scenarios come up often enough that they deserve their own space.

What About Custom Orthotics?

Custom orthotics from a podiatrist are a gray area that Medicare handles inconsistently. Medicare only covers foot orthotics in specific clinical situations, not as general arch support or comfort devices. If your doctor prescribes custom orthotics for a covered condition like severe diabetic neuropathy, Part B may cover them. If you’re buying them for plantar fasciitis or general foot pain, you’re almost certainly paying out of pocket, and your Medigap plan won’t help because Medicare didn’t approve the original claim.

Prosthetic Replacements

Medicare does cover replacement prosthetics, but the rules are strict. You typically need documentation showing the device is worn out, damaged beyond repair, or your condition has changed enough to require a different fit or type. Keep your doctor involved and make sure there’s a clear paper trail. Without it, a replacement claim can get denied, which means your Medigap plan has nothing to cover either.

People With Medicare Advantage Instead of Medigap

If you’re on a Medicare Advantage plan instead of Original Medicare plus Medigap, the rules are different. Advantage plans cover orthotics and prosthetics as required by Medicare, but your out-of-pocket costs depend entirely on your specific plan’s cost-sharing structure. Some Advantage plans have lower costs for DME, others have higher. You need to read your plan’s Evidence of Coverage carefully, or call the plan directly. This article is specifically about Medigap, but it’s worth knowing the distinction so you’re not comparing apples to oranges.

Bottom Line

For most people who need orthotics or prosthetics, Plan G is the right Medigap plan. It covers that 20% coinsurance completely after your $257 Part B deductible (2026), which on a major prosthetic device is thousands of dollars of protection for what amounts to a modest monthly premium. The most important things you can do are make sure your device is prescribed by a physician, use a Medicare-enrolled supplier who accepts assignment, and get that medical necessity documentation in writing before any purchase is made.

Frequently Asked Questions

Does Medicare pay for prosthetic limbs?

Yes. Medicare Part B covers prosthetic limbs when they’re prescribed as medically necessary by your physician. Part B pays 80% of the Medicare-approved amount after the annual deductible ($257 in 2026), and a Medigap plan like Plan G covers the remaining 20%.

Will Medicare cover a new prosthetic if the old one wears out?

Generally yes, but you’ll need documentation from your doctor showing the replacement is medically necessary. Prosthetics don’t have a fixed replacement schedule under Medicare — it’s based on medical need, not time elapsed. Keep detailed records and work closely with your physician on the paperwork.

Does Medicare cover back braces or knee braces?

Medicare Part B covers back braces, knee braces, and other orthotic devices when they’re prescribed by a doctor for a covered medical condition and supplied by a Medicare-enrolled DME provider. Over-the-counter braces you buy without a prescription generally aren’t covered.

What if my doctor says I need an orthotic but Medicare denies it?

You have the right to appeal. Your doctor can submit additional documentation supporting medical necessity. If Medicare ultimately denies the claim, your Medigap plan won’t cover it either since Medigap only pays after Medicare approves. That’s why getting solid documentation before the purchase matters so much — a denied claim becomes entirely your expense regardless of what Medigap plan you have.

Medicare Supplement Plans Don’t Cover Dependents — Period

If you’re hoping to add your adult child to your Medigap policy, I’ll save you the trouble: it’s not possible, and it never has been. Medicare supplement insurance is written specifically for Medicare beneficiaries, and Medicare itself is an individual program. There’s no family plan. No add-on option. No workaround. Your adult child simply cannot be covered under your Medigap policy, regardless of which plan letter you pick or which insurer you call.

I know that’s not what some people want to hear, especially parents who are used to employer-sponsored insurance where you could cover a spouse, kids, even adult children up to age 26 under the Affordable Care Act. That model doesn’t translate to Medicare at all. The structure is completely different, and understanding why helps you stop looking for a door that isn’t there.

Medicare is a federal health insurance program for people who are 65 or older, or for younger people with certain disabilities or end-stage renal disease. Medigap policies exist to fill the gaps in Medicare — the Part A deductible (which in 2026 is $1,676 per benefit period), the 20% coinsurance under Part B, and so on. Since your adult child isn’t on Medicare, there’s nothing for a Medigap plan to supplement. The coverage would be meaningless even if an insurer tried to sell it to you, which they won’t, because it’s not a product that legally exists.

How This Is Different From Employer Coverage and ACA Plans

A lot of confusion comes from people comparing Medicare to what they had before retirement. Under employer-sponsored group insurance, you could often cover your whole family. Under the ACA, young adults can stay on a parent’s health plan until age 26. So it’s understandable to wonder if Medicare works similarly. It doesn’t, and here’s why.

Employer plans are group contracts. The employer negotiates a deal with an insurer to cover employees and their eligible dependents. That’s a private contract, and the rules around who counts as a dependent are set by the employer and insurer together, within IRS and ACA guidelines. Medicare isn’t a private contract. It’s a federal entitlement program with its own statute, and that statute doesn’t include dependent coverage.

Medigap policies are individual policies layered on top of individual Medicare coverage. Every insurer selling Medigap is required by law to follow standardized plan designs (Plan G, Plan N, Plan F, etc.), and none of those designs include dependent coverage. An insurer can’t invent a “family Medigap” option even if they wanted to, because the federal and state regulations governing these plans simply don’t allow it.

That said, this doesn’t mean your adult child is out of options. It means their coverage has to come from a completely separate source, which I’ll get to in a moment.

The Common Mistake: Confusing Medicare Advantage With Medigap

In my experience, the people most likely to ask about covering adult children on a Medicare plan have often confused Medicare Advantage (Part C) with Medigap. I see this mix-up constantly, and it matters because the two work very differently.

Medicare Advantage plans are offered by private insurers as an alternative way to receive your Medicare benefits. Some people assume that because these are private insurance products, they might work more like commercial health plans and allow dependents. They don’t. Medicare Advantage is still Medicare. Enrollment still requires that each individual be Medicare-eligible. You can’t add a 35-year-old to your Medicare Advantage plan any more than you can add them to Original Medicare.

There’s also a related misconception that if your adult child has a disability and qualifies for Medicare on their own, they can somehow be linked to your plan. That’s not how it works either. If your child qualifies for Medicare due to a disability, they get their own Medicare enrollment, their own card, and their own Medigap eligibility. They’d need to apply for their own Medigap policy separately. The good news there is that they have that option, though coverage can sometimes be harder to get without the standard enrollment protections that apply at age 65.

Plan Type	Covers Dependents?	Who Can Enroll?	Private or Federal?
Original Medicare (Parts A & B)	No	Medicare-eligible individuals only	Federal
Medigap (Medicare Supplement)	No	Medicare-enrolled individuals only	Private, federally regulated
Medicare Advantage (Part C)	No	Medicare-eligible individuals only	Private, federally contracted
Employer-Sponsored Insurance	Yes (typically)	Employees and eligible dependents	Private
ACA Marketplace Plans	Yes (up to age 26)	Any U.S. resident not eligible for Medicare/Medicaid	Private, ACA-regulated

What Your Adult Child Should Actually Do For Coverage

Here’s what I’d tell any parent asking this question: stop trying to find a way to put your child on your Medicare plan, because that energy is wasted. Redirect it toward finding them their own coverage, which is genuinely available and in many cases quite affordable.

If your adult child is employed, their best option is usually their employer’s health plan, assuming one is offered. That’s the most straightforward path. If they’re self-employed, freelancing, or working for a small business that doesn’t offer benefits, the ACA Marketplace is where they should go. Depending on their income, they may qualify for significant premium subsidies. A 30-year-old in Ohio earning $40,000 a year could easily qualify for a subsidized silver plan that costs well under $200 a month, sometimes much less.

If your adult child is low-income, they may qualify for Medicaid, which is free or nearly free and covers a wide range of services depending on the state. It’s worth checking eligibility even if they think they won’t qualify, because the income thresholds are higher in states that expanded Medicaid under the ACA.

Short-term health plans exist too, but I’d be cautious here. They’re cheap because they cover very little, often exclude pre-existing conditions, and can leave someone with massive bills after a serious illness or injury. They’re a last resort, not a plan.

One more option worth mentioning: if your adult child is under 26, they can be covered as a dependent on a parent’s ACA Marketplace plan or employer plan, but only if the parent isn’t yet on Medicare. Once you’ve moved to Medicare, that door closes. So if you’re approaching 65 and your child is still under 26, make sure they have a plan in place before you transition off any employer group coverage you currently have.

If Your Adult Child Is Disabled and Might Qualify for Medicare

This deserves its own section because it comes up more than people expect. If your adult child has a serious disability, they may qualify for Medicare before age 65 through Social Security Disability Insurance (SSDI). After receiving SSDI for 24 months, a person becomes eligible for Medicare Parts A and B, regardless of age.

Once they’re on Medicare, they can apply for their own Medigap policy. The tricky part is that Medigap insurers in most states are not required to sell to Medicare beneficiaries under age 65 without medical underwriting. That means your child could be denied or charged higher premiums based on their health history. A handful of states, including New York and Connecticut, have stronger protections that guarantee Medigap access regardless of age or health status. If you’re in one of those states, your child has more options.

For a 45-year-old disabled Medicare beneficiary in Texas, for example, getting a Plan G policy without guaranteed issue protections could be very difficult depending on their conditions. An independent broker who works with multiple carriers is the best resource in that situation, not a captive agent for one company.

Bottom Line

Medicare supplement coverage for adult children as dependents isn’t an option that exists in any form, and no insurer, broker, or agent can create one for you. Your adult child needs their own coverage, and the ACA Marketplace, employer plans, and Medicaid are all real paths worth exploring based on their situation. Don’t spend another minute looking for a Medigap workaround that doesn’t exist when legitimate coverage is available for your child right now.

Frequently Asked Questions

Can my spouse be on my Medicare supplement plan?

No. Just like adult children, your spouse cannot be added to your Medigap policy. If your spouse is also Medicare-eligible, they need to enroll in Medicare on their own and apply for their own Medigap plan separately. If your spouse is under 65 and not Medicare-eligible, they’ll need their own coverage through an employer, the ACA Marketplace, or Medicaid.

My adult child is disabled and on SSDI. Can they get Medigap?

Possibly, but it depends on your state. After 24 months on SSDI, your child becomes Medicare-eligible and can apply for Medigap. However, insurers in most states can deny coverage or charge higher premiums to under-65 enrollees based on health status. States like New York, Connecticut, and Massachusetts have stronger protections. Work with an independent broker who knows the rules in your specific state.

Can I buy a separate Medigap-like plan for my adult child who isn’t on Medicare?

No product like this exists. Medigap is specifically designed to wrap around Medicare benefits, so it’s meaningless without an underlying Medicare enrollment. For a non-Medicare adult, the right products are ACA Marketplace plans, employer health insurance, or Medicaid. These are real insurance products with real coverage, not a substitute for Medigap.

What happens to my adult child’s coverage when I turn 65 and move to Medicare?

If your child was on your employer’s group health plan as a dependent, your move to Medicare typically triggers a Special Enrollment Period for them. They’ll usually have 60 days to enroll in their own coverage through the ACA Marketplace or another source without a coverage gap. Don’t miss that window. Missing it means waiting for the next Open Enrollment Period, which runs November 1 through January 15, and a potential gap in coverage in the meantime.

The Hard Truth: Medigap Doesn’t Cover Routine Eye Exams

Here’s something nobody tells you clearly enough when you’re shopping for Medicare coverage: no Medigap plan covers routine eye exams. Not Plan G. Not Plan N. Not any of them. I’ve watched people spend hours comparing Medicare supplement plans thinking they’re going to find the one that covers their annual vision checkup, and it doesn’t exist.

That’s not a knock on Medigap. It’s just reality, and understanding why this is the case will save you a lot of confusion.

Original Medicare (Parts A and B) excludes routine vision care almost entirely. Part B only covers eye exams when they’re medically necessary, meaning there’s a diagnosed condition involved, like glaucoma screening for high-risk patients, or treatment for diabetic retinopathy. Because Medigap policies are designed to fill in the gaps left by Medicare Parts A and B, they follow the same boundaries. If Medicare doesn’t pay for something, a Medigap plan generally won’t either. That’s the architecture of the system, and it’s not going to change anytime soon.

So what do you actually do if you need vision coverage? And where does Medigap fit into a larger plan for keeping your eye care costs under control? That’s what this article is going to walk you through, because there are real options, and some of them are genuinely good.

What Medicare (and Medigap) Actually Covers for Your Eyes

Before you write off Medicare coverage for eyes entirely, let’s be precise about what it does and doesn’t do. The distinction matters.

Part B will cover an eye exam when it’s medically necessary to diagnose or treat a condition. The most common examples include:

• Annual glaucoma screenings for people at high risk (those with diabetes, a family history of glaucoma, African Americans over 50, or Hispanic Americans over 65)
• Diabetic retinopathy exams for people with diabetes
• Cataract surgery, including one pair of glasses or contact lenses afterward
• Treatment for macular degeneration, including injections like Avastin or Lucentis
• Eye exams related to injury or acute disease

For all of these covered services, a Medigap plan does kick in. If you have Plan G, for example, it pays your 20% coinsurance after you’ve met the 2026 Part B deductible of $257. That’s legitimate protection. If you need cataract surgery, a solid Medigap plan can save you real money.

What it won’t touch is the annual refractive exam to update your glasses prescription. It won’t cover eyeglasses or contact lenses outside of post-cataract surgery. It won’t cover the standard “how’s your vision this year” checkup that most people over 65 get regularly.

So to be direct: Medigap is valuable for serious eye conditions and procedures. It’s not your solution for routine vision maintenance.

The Right Way to Get Routine Vision Coverage in Retirement

Since Medigap won’t cover your annual eye exam, you’ve got a few real options, and I have opinions about which ones are worth your time.

Option 1: A standalone vision plan. These typically cost $10 to $20 per month and cover one eye exam per year plus an allowance toward glasses or contacts, usually $100 to $200. Companies like VSP, EyeMed, and Davis Vision sell directly to individuals. For most people who just want to keep their prescription current, this is the simplest, cheapest fix. I’ve seen people pay $15/month and come out ahead every single year because their eye exam alone runs $150 out of pocket.

Option 2: Medicare Advantage (Part C) instead of Original Medicare plus Medigap. Medicare Advantage plans are required to cover everything Original Medicare covers, and most of them add vision, dental, and hearing benefits on top of that. This is the option the insurance industry loves to advertise, and it does have a real advantage here. But I want to be honest about the tradeoff: most Medicare Advantage plans use provider networks and prior authorization requirements that Medigap does not. You’re trading flexibility for extra benefits. Whether that’s worth it depends on your health situation, not just your eye exam needs.

Option 3: Discount vision programs. Costco Optical, America’s Best, and similar retailers offer low-cost exams that don’t require insurance at all. A comprehensive eye exam at Costco often runs $70 to $90. If you’re healthy and only need a routine checkup, paying out of pocket at a discount retailer might be cheaper than paying monthly premiums for a vision plan.

My recommendation for most people: get a strong Medigap plan for real medical protection, then add a standalone vision plan or just use a discount retailer for routine eye care. Don’t let the vision gap push you away from Medigap entirely.

The Big Misconception I See All the Time

People assume that Medicare Advantage is better because it includes vision coverage. I understand why. On paper, getting vision, dental, and hearing bundled in feels like a win. But I’ve seen too many people in their mid-70s regret switching to Medicare Advantage when a serious health issue hits.

Here’s the actual comparison for a 65-year-old thinking about this decision:

Coverage Type	Monthly Premium (approx.)	Routine Eye Exam	Cataract Surgery Coverage	Provider Network
Plan G + Standalone Vision	$130 to $165 (Plan G) + $15 (vision)	Yes, through vision plan	Pays 20% coinsurance after $257 deductible	Any Medicare-accepting provider in the U.S.
Medicare Advantage (typical)	$0 to $60	Yes, usually 1 exam/year	Covered, subject to copays and prior auth	Restricted to plan network
Plan N + Standalone Vision	$100 to $135 (Plan N) + $15 (vision)	Yes, through vision plan	Pays 20% coinsurance after $257 deductible	Any Medicare-accepting provider in the U.S.

The Medicare Advantage premium looks attractive. But that $0 to $60 premium comes with cost-sharing when you actually use care. A hospital stay or a serious specialist visit can cost you thousands in copays, and you may need prior authorization for procedures your doctor recommends. A 67-year-old in Ohio who develops a cardiac issue mid-year will care a lot more about network access and out-of-pocket maximums than about a free eye exam.

Don’t choose your core health coverage strategy based on vision benefits. It’s a category error. Get the right foundational coverage first, then add vision on top.

How to Shop Smart If You Do Want Vision Coverage Bundled In

If you’ve weighed the tradeoffs and you want to go the Medicare Advantage route partly for the vision benefits, at least shop it correctly. Not all Medicare Advantage plans are created equal on this.

When you’re comparing plans on Medicare.gov or through a broker, look specifically at:

1. The exam allowance. Most plans cover one exam per year. Some cover two. Make sure the covered exam includes a comprehensive dilated exam, not just a basic screening.
2. The eyewear allowance. Ranges from $100 to $500 depending on the plan. Understand whether that’s per year or per two years.
3. In-network providers. Check whether your current eye doctor is actually in the plan’s network before you enroll. Don’t assume.
4. Whether the allowance applies to frames and lenses or just one. Some plans will cover the exam and give you credit toward lenses, but frames are extra. Read the fine print.

A plan that advertises “vision benefits” may offer $100 toward eyewear every two years. If you spend $400 on glasses annually, that’s not much of a benefit. Run the actual numbers before you assume you’re getting a deal.

Bottom Line

No Medicare supplement plan covers routine eye exams, and you shouldn’t expect one to. For most people, the right move is to get a strong Medigap plan like Plan G to protect against serious medical costs, then handle routine vision care separately with a $15/month standalone vision plan or a discount retailer. Don’t abandon the financial protection that Medigap offers just because it doesn’t cover your annual eye checkup. The math almost never works out in your favor when you do.

Frequently Asked Questions

Does Plan G cover eye exams?

Plan G does not cover routine eye exams. It covers your 20% coinsurance for any service that Medicare Part B pays for, which includes medically necessary eye care like cataract surgery, glaucoma screenings for high-risk patients, and treatment for diabetic eye disease. Your standard annual vision checkup isn’t covered by Part B, so Plan G won’t cover it either.

Can I add vision coverage to my Medigap plan?

No. Medigap plans are standardized by federal law and can’t be bundled with extra benefits like vision or dental. You’d need to purchase a separate standalone vision plan. They’re inexpensive and widely available from companies like VSP or EyeMed, and they’re not connected to your Medigap coverage at all.

What’s the cheapest way to get vision coverage on Medicare?

Honestly? If you’re healthy and just need an annual exam and updated glasses prescription, paying out of pocket at a discount retailer like Costco Optical or America’s Best is often cheaper than paying monthly premiums for a vision plan. Exams run $70 to $90, and glasses can be very affordable. If you have more complex vision needs or want the predictability of a plan, a standalone vision plan for $10 to $20 per month is the next step up.

Does switching to Medicare Advantage give me better eye coverage?

Most Medicare Advantage plans do include routine vision benefits, which Medigap doesn’t offer. That’s a real advantage. But Medicare Advantage comes with provider networks, prior authorization requirements, and cost-sharing that can get expensive when you have serious health needs. I’d encourage you to evaluate the full tradeoff, not just the vision piece, before switching. For many people over 65 with ongoing health conditions, the freedom and predictability of Medigap plus a cheap standalone vision plan is the better overall value.

Medicare Supplement Covers More Than You Think — But It Has Real Blind Spots

Medigap is genuinely excellent insurance. I’ll say that upfront, because I don’t want to bury the lead with a list of problems before you understand the context. For most people, a Plan G or Plan N handles the overwhelming majority of what Medicare leaves unpaid — hospital cost-sharing, doctor visit coinsurance, foreign travel emergencies, and more. But there are specific expenses it won’t touch. And those gaps trip people up constantly, especially in the first year after enrolling.

So here’s the honest answer: Medicare Supplement does not cover prescription drugs, dental care, vision care, hearing aids, long-term custodial care, or routine foot care. It also won’t pay the Part B deductible if you’re on Plan N or Plan G (Plan G covers everything else; Plan N has copays). That’s the short list. The details matter more than the categories, so let’s get into them.

The Big Four: Prescriptions, Dental, Vision, and Hearing

These four categories account for most of the “wait, Medigap doesn’t cover that?” moments I hear about. They’re excluded because Medigap is specifically designed to fill the gaps inside original Medicare — Parts A and B. Medicare itself doesn’t cover these things as a general rule, so there’s nothing for Medigap to supplement.

Prescription drugs are the most financially significant of the four. If you skip Part D coverage because you think your Medigap plan has you covered, you’re going to have a problem. I’ve talked to people who went 18 months without a Part D plan because they assumed the supplement “handled everything.” It doesn’t. You need a standalone Part D plan on top of your Medigap policy. They’re sold separately and priced separately.

Dental is the one that consistently shocks people. A crown can run $1,200 to $2,000 out of pocket. Implants are often $3,000 or more per tooth. Original Medicare doesn’t cover routine cleanings, fillings, extractions, or periodontal work — and since Medigap only fills Medicare’s gaps, it doesn’t either. If you have significant dental needs, you need a standalone dental plan or a Medicare Advantage plan that includes dental benefits. That said, Medicare Advantage comes with tradeoffs, so don’t jump ship from Medigap just for dental coverage without thinking it through.

Vision and hearing are similar. Routine eye exams, glasses, contact lenses, and hearing aids are all excluded from original Medicare and therefore from Medigap. Medicare does cover certain medically necessary eye care — like treatment for glaucoma or cataracts — but your annual eye exam and your $4,000 hearing aids? That’s on you. Standalone vision and hearing plans exist, and they’re usually affordable ($20-$50/month range), so don’t ignore them just because they seem like a hassle to set up.

Long-Term Care: The Gap Most People Underestimate

This one deserves its own section because the financial stakes are so much higher. Medigap does cover skilled nursing facility coinsurance — that’s the cost-sharing for days 21 through 100 in a skilled nursing facility after a qualifying hospital stay. Plan G covers that in full. But that’s not the same as long-term custodial care, which is what most people actually end up needing.

Custodial care means help with activities of daily living: bathing, dressing, eating, using the bathroom. It’s what happens when you’re not “sick” enough for skilled nursing but not independent enough to live without assistance. A private room in a nursing home averaged over $100,000 per year nationally in recent years. Medicare pays none of it. Medigap pays none of it. Medicaid pays it only after you’ve spent down most of your assets.

Long-term care insurance exists specifically for this. It’s expensive and harder to qualify for once you’re already in your 70s, which is why I tell anyone who’s still in their early 60s and reading this: don’t wait. If you’re 68 or older and in decent health, hybrid life/LTC policies are worth looking at as an alternative. This is a genuine planning issue, not just an insurance gap.

The Common Mistake: Thinking Plan G Covers Everything

In my experience, this is the #1 misconception among people who’ve recently enrolled in Medigap. They buy Plan G, they feel like they’re fully protected, and then they get blindsided. Plan G is the best all-around Medigap plan available to most people, and I’d recommend it to a 65-year-old in most states without hesitation. But “best available” isn’t the same as “covers everything.”

Here’s what Plan G actually covers versus what it doesn’t:

Expense Type	Does Plan G Cover It?	Notes
Part A hospital coinsurance	Yes	Days 61-90 and beyond
Part B coinsurance (20%)	Yes	For Medicare-approved services
Part A deductible	Yes	2026 amount: $1,676 per benefit period
Part B deductible	No	2026 amount: $257 per year — you pay this
Skilled nursing facility coinsurance	Yes	Days 21-100 after qualifying stay
Prescription drugs	No	Need separate Part D plan
Dental care	No	Standalone dental plan needed
Vision/Hearing	No	Separate coverage needed
Long-term custodial care	No	Not covered by Medicare at all
Foreign travel emergencies	Yes (80%)	After $250 deductible; $50,000 lifetime limit

The Part B deductible is a small thing — $257 in 2026 — but it surprises people who assumed Plan G was truly “gap-free.” It’s the one cost-sharing item Plan G doesn’t pick up. If that bothers you, Plan F eliminates it, but Plan F is only available to people who were eligible for Medicare before January 1, 2020. For most people enrolling today, Plan G is still the right call; $257 a year shouldn’t change your decision.

Other Expenses Medicare Supplement Won’t Cover

Beyond the big categories, there are some smaller but genuinely annoying exclusions worth knowing about.

Routine foot care is excluded unless there’s a medical condition — like diabetes with peripheral neuropathy — that makes it medically necessary. If you just want your toenails trimmed by a podiatrist, Medicare won’t pay for it and neither will Medigap.

Cosmetic surgery is excluded unless it’s reconstructive after an injury or illness. That’s a standard exclusion across basically every health insurance product, so it shouldn’t surprise anyone.

Services not approved by Medicare are a bigger deal than people realize. Medigap only covers cost-sharing for services Medicare has already agreed to pay its portion on. If a provider doesn’t accept Medicare assignment, or if Medicare denies a claim as not medically necessary, Medigap won’t step in. There’s a limited exception for “excess charges” in Plan G (it covers them, up to 15% above Medicare’s approved rate), but if Medicare denies the claim entirely, you’re on your own.

Acupuncture is a borderline case. Medicare does cover limited acupuncture for chronic low back pain now, and in those cases Plan G would cover the 20% coinsurance. But acupuncture for anything else? Not covered by Medicare, not covered by Medigap.

There’s also the question of private-duty nursing beyond what Medicare covers. If you need around-the-clock nursing care at home and Medicare’s home health benefit doesn’t cover the full scope of what you need, Medigap won’t fill that gap either. This circles back to the long-term care conversation.

Bottom Line

Plan G is still the right Medigap plan for most people enrolling at 65, and it genuinely covers the vast majority of out-of-pocket costs under original Medicare. But you need a separate Part D drug plan, you should strongly consider standalone dental and vision coverage, and if long-term care is a concern, address that independently with an LTC or hybrid policy. Don’t let the gaps listed here scare you away from Medigap — just go in with your eyes open.

Frequently Asked Questions

Does Medicare Supplement cover dental implants?

No. Neither original Medicare nor any Medigap plan covers dental implants, dentures, routine cleanings, or most other dental work. You’ll need a standalone dental plan for that. Some people opt for Medicare Advantage instead because certain plans include dental benefits, but weigh that decision carefully since Advantage plans restrict your provider network in ways Medigap doesn’t.

Will my Medigap plan cover prescriptions I take every day?

No. Medigap has not covered prescription drugs for plans sold after 2006. You need a standalone Part D Prescription Drug Plan to cover medications. If you skip Part D and try to enroll later, you’ll face a late enrollment penalty — a permanent premium surcharge — so don’t put it off thinking your Medigap handles it.

What happens if Medicare denies a claim — does Medigap still pay?

Generally no. Medigap covers cost-sharing for services Medicare approves. If Medicare denies a claim as not medically necessary, or the service simply isn’t covered by Medicare at all, your Medigap plan won’t pick up the tab. This is why it’s worth understanding what Medicare covers before assuming you’re protected against a specific expense.

Does Medicare Supplement cover hearing aids?

No. Hearing aids are specifically excluded from original Medicare coverage, so Medigap has nothing to supplement there. Hearing aids can cost $2,000 to $7,000 or more depending on technology level. You can buy a standalone hearing benefit plan, or look at over-the-counter hearing aids if your hearing loss is mild to moderate. It’s one of the most frustrating gaps in the entire Medicare system.

What Actually Changes in Medigap Between Plan Years

Your Medigap plan doesn’t get renegotiated every year the way an Advantage plan does, but that doesn’t mean nothing changes. A few things shift annually, and if you’re not paying attention, they can quietly cost you more money than you expected.

The biggest annual changes aren’t in the plan structure itself. They’re in the underlying Medicare costs that your Medigap plan is covering. Here’s the key distinction: Medigap plans are standardized by letter (Plan G is Plan G no matter who sells it), but the gaps they fill shift based on what Medicare sets as its cost-sharing amounts each year. When those numbers go up, your plan is doing more work. When they go down (which is rare), you get a small break.

For 2026, the Part A deductible is $1,676 per benefit period. The Part B deductible is $257. If you have Plan G, you’re covering that Part B deductible yourself, since Plan G covers almost everything except that one deductible. If you have Plan F, Medicare covers it for you. Those aren’t hypothetical numbers. They’re what you’re working with right now, and they’re different from what they were in 2024 or 2025.

Your premium, on the other hand, is set by your insurer, not Medicare. And that’s where things get genuinely complicated.

Premium Increases Are the Change That Hurts Most People

I’ve seen people sign up for a Medigap plan, feel great about their monthly cost, and then act surprised three years later when their premium is 20% higher. The plan didn’t change. Medicare didn’t change it. Their insurer raised the rate, and they had no legal protection stopping it from happening.

Medigap insurers can raise your premium annually for several reasons. Medical inflation is the one they’ll cite. But rating method matters enormously here, and most people don’t know which one their plan uses when they buy it.

• Community-rated plans charge everyone in a geographic area the same premium, regardless of age. Your premium still goes up with inflation, but it won’t balloon just because you’re getting older.
• Issue-age-rated plans lock in your rate based on how old you are when you first buy. Younger buyers get a lower starting rate. It won’t increase just because you age, but inflation increases still apply.
• Attained-age-rated plans increase every year as you get older, on top of any inflation increases. These often have the lowest starting premiums, which is exactly why they’re dangerous for long-term planning.

A 65-year-old in Texas buying an attained-age-rated Plan G at $110 a month might be paying $180 or more by age 75. Same plan. Same benefits. Just an older policyholder. If that person had bought a community-rated plan at $145 a month to start, they’d likely be paying less a decade later, not more.

The honest answer is that attained-age rating is a bad deal for most people who plan to keep their Medigap coverage long-term. The initial savings rarely hold up.

The Mistake People Make When Benefits Get Standardized or Changed

Here’s a misconception I see constantly: people assume that if Congress or CMS makes changes to Medigap plan structures, their existing plan automatically updates to match. It doesn’t. At all.

The last major restructuring happened in 2020, when Plans C and F were closed to people newly eligible for Medicare. Anyone who already had those plans kept them. People turning 65 in 2020 or later couldn’t buy them. That change happened, and plenty of people thought they could still get Plan F because their neighbor had it. They couldn’t.

If new standardization changes come in the future (and there’s always chatter in Washington about modernizing the benefit structure), the same principle applies. Grandfathered plans stay the same. New enrollees get whatever the current rules allow. Your existing plan is a contract. It doesn’t morph based on legislative tinkering.

The flip side is also true, and it matters. If your current plan gets discontinued, you typically have guaranteed issue rights to move to a comparable plan. But outside of that specific scenario, switching plans means going through underwriting if you’re past your initial open enrollment window. And in most states, if you have health conditions, underwriting can mean denial. This is why I tell people to choose their plan carefully the first time rather than assuming they can switch freely later.

What Changes Year to Year: A Side-by-Side Look

To make this concrete, here’s how some of the key numbers and factors shift from one plan year to the next. This isn’t exhaustive, but these are the ones that affect your out-of-pocket costs in a real way.

Factor	Who Sets It	2025 Amount	2026 Amount	Does Your Plan Cover It?
Part A deductible (per benefit period)	Medicare/CMS	$1,676	$1,676	Plan G, Plan F: yes. Plan N: yes. Plan K/L: partial.
Part B deductible	Medicare/CMS	$240	$257	Plan F only. Plan G does NOT cover this.
Part B excess charges	Set by Medicare rules	Up to 15% above Medicare rate	Up to 15% above Medicare rate	Plan G and Plan F: yes. Plan N: no.
Skilled nursing coinsurance (days 21-100)	Medicare/CMS	$209.50/day	$209.50/day	Plan G and Plan F: yes. Plan N: yes. Plan K/L: partial.
Your Medigap premium	Your insurer	Varies	Varies (typically 3-8% increase)	N/A

The Part B deductible jump from $240 to $257 in 2026 isn’t going to wreck your finances. But it’s a real number, and if you’re on Plan G, you’re writing that check yourself in January when you first see a doctor. Plan accordingly.

When to Actually Consider Switching Plans

Most of the time, you should stay put. Switching Medigap plans is not like switching car insurance. There are real consequences if you’ve had any health issues since you first enrolled, because insurers can deny you or charge you more based on your health history in most states. That protection from medical underwriting only exists during specific windows.

That said, there are situations where looking at a switch genuinely makes sense.

1. Your premium has increased dramatically and you’re still in good health. If you’re a 68-year-old in excellent health and your attained-age-rated premium has jumped $50 a month in two years, shopping around during a state-specific open enrollment period or guaranteed issue window could save you real money. But you have to qualify medically in most states.
2. Your insurer is exiting your market. This is rare, but it happens. If your plan is being discontinued, you get guaranteed issue rights to switch. Don’t ignore those notices.
3. You’ve moved to a state with a continuous open enrollment period. A handful of states, including New York and Connecticut, require insurers to offer Medigap plans without medical underwriting year-round. If you live there, switching is much lower-risk.
4. Your actual healthcare use has changed significantly. Someone who started with Plan N because they rarely saw doctors but now has a chronic condition might be better served by Plan G. If you can still medically qualify, a switch might make financial sense over a five-year horizon.

I wouldn’t switch plans just because someone told you a better deal exists. Run the actual numbers, factor in your health situation, and think about the next five to ten years, not just next month’s premium.

Bottom Line

For most people, the plan changes that matter most between Medigap years aren’t in your plan document, they’re in your premium and the underlying Medicare cost-sharing amounts. Plan G is still the best option for most new enrollees in 2026: it covers nearly everything, it’s widely available, and it doesn’t expose you to the risk of paying excess charges. If your premiums are climbing faster than inflation and you’re in good health, it’s worth shopping around, but go in with clear eyes about what underwriting means in your state.

Frequently Asked Questions

Can my Medigap plan’s benefits change without my consent?

Technically, insurers can make minor administrative changes, but they can’t strip out standardized benefits without state insurance department approval. The core benefit structure of your plan is protected. What they can and do change is your premium, and they can do that with proper notice, usually 30 days before it takes effect.

Do I have to re-enroll in my Medigap plan each year like with Medicare Advantage?

No. This is one of the biggest differences between Medigap and Medicare Advantage. Your Medigap policy renews automatically as long as you pay your premiums and your insurer stays in your market. There’s no annual election period and no action required on your part to keep your coverage.

If Medicare raises the Part B deductible, does my Plan G premium go up automatically?

Not automatically, no. Your Plan G premium is set by your insurer and is based on their own claims experience, inflation projections, and business decisions. The Part B deductible increase affects how much Plan G holders pay out of pocket at the start of the year (since Plan G doesn’t cover it), but it doesn’t trigger a direct premium increase. Premiums go up for separate reasons.

Can I switch from Plan G to Plan N to save money on premiums?

You can try, but in most states you’ll need to pass medical underwriting. If you’re healthy, it may be worth exploring. Plan N typically costs $20-$40 less per month than Plan G, but it doesn’t cover Part B excess charges, and you’ll pay small copays for some office visits. If you see doctors who don’t accept Medicare assignment, Plan N can actually cost you more. Know what you’re trading before you make that call.

Your Open Enrollment Window Is the Only Time You’re Guaranteed Coverage

The best time to enroll in a Medicare supplement plan is during your Medigap Open Enrollment Period, which starts the month you turn 65 and are enrolled in Medicare Part B. You get exactly six months. That window closes whether you use it or not, and once it’s gone, most states won’t give it back.

Here’s why that window matters so much: during those six months, insurance companies are legally required to sell you any Medigap plan they offer at their standard rates. They can’t ask about your health. They can’t turn you down for a pre-existing condition. They can’t charge you more because you had cancer three years ago or because you take five medications. That’s called guaranteed issue, and it only exists automatically during this specific window.

Outside of open enrollment, insurers in most states can run you through medical underwriting. That means they ask detailed questions about your health history, and they can decline your application entirely or charge you a higher premium based on what they find. I’ve seen people in their late 60s get flat-out rejected because of conditions as common as well-managed diabetes or a history of sleep apnea. It’s not a theoretical risk. It happens constantly.

So if you’re approaching 65, the single most actionable thing I can tell you is: don’t wait, and don’t assume you’ll be able to get coverage later. Enroll during your open enrollment window, even if you feel perfectly healthy right now.

What “Turning 65” Actually Means for Your Timeline

Your Medigap Open Enrollment Period starts on the first day of the month you turn 65, provided you’re already enrolled in Medicare Part B. That second part trips people up more than anything else I’ve seen.

If you delayed Part B enrollment because you had employer coverage, your six-month Medigap window doesn’t start at 65. It starts when you actually enroll in Part B. So a 68-year-old who just retired and signed up for Part B this month gets a full six-month Medigap window starting now. Age 65 isn’t the trigger. Part B enrollment is.

That’s genuinely good news for people who work past 65. You’re not penalized just for delaying. But here’s the catch: you need to enroll in Part B promptly when your employer coverage ends. If you let Part B enrollment lapse or miss a deadline, you could end up in a gap situation where you’ve also lost your Medigap guaranteed issue rights, and now you’re trying to get coverage in your late 60s with a health history that makes underwriting risky.

One more thing worth knowing: if your birthday is on the first of the month, Medicare considers your coverage to begin on the first of the prior month. It’s a quirk in how Social Security calculates benefit start dates. If that applies to you, verify your exact Part B start date with Social Security directly before assuming your Medigap window dates.

The Timing Mistake That Costs People Thousands

I want to be direct about the most common mistake I see: people wait until they actually get sick or have a major procedure scheduled, and then they try to buy a Medigap plan. By that point, they’re either denied outright or they’re stuck with whatever options are available to them at unfavorable rates.

The misconception driving this mistake is that Medigap works like a product you can shop for when you need it. It doesn’t. It’s closer to life insurance in how it’s underwritten outside of protected windows. You can’t wait until you have a heart condition to buy coverage that helps pay for cardiac care. The insurer knows exactly what you’re going to use it for, and they’ll decline you.

A related mistake is assuming that Medicare Advantage is a fine backup plan if you can’t get Medigap. In the short term, it might be. But Medicare Advantage plans come with networks, prior authorizations, and cost-sharing structures that can get expensive fast when you’re dealing with serious illness. I’ve talked with people in their early 70s who ended up on Advantage plans after losing their Medigap window, racking up thousands in out-of-pocket costs during hospitalizations that a Plan G would have covered almost entirely.

The 2026 Part A deductible is $1,676 per benefit period. The 2026 Part B deductible is $257. Those aren’t numbers you want to face repeatedly in a bad health year without a supplement. Plan G covers both once you pay the Part B deductible yourself. That’s the whole point of having it.

When You Can Still Get Guaranteed Issue After Your Main Window

There are situations where federal law guarantees you the right to buy a Medigap plan even outside your initial open enrollment window. These are called Special Enrollment Periods or guaranteed issue rights, and it’s worth knowing when they apply.

The main scenarios where you’re protected include:

• Your Medicare Advantage plan is leaving your area or stopping operations
• You move out of your Medicare Advantage plan’s service area
• You had employer group health coverage that ends
• You enrolled in Medicare Advantage when you first became eligible and you want to switch back to Original Medicare within 12 months
• You lose Medicaid coverage you previously had

These rights are federal guarantees, but they’re narrow. They apply to specific plan types, and in most cases you’re limited to buying Plan A, B, C, F, K, or L from any insurer, or Plan D or G from certain insurers. You can’t always get any plan you want.

Some states give their residents broader protections. California, Connecticut, Maine, Massachusetts, Missouri, New York, and Washington have their own rules that provide more open enrollment opportunities or limit underwriting more strictly than federal law. If you live in one of these states, check your state-specific rules before assuming federal minimums are all you have.

How Premium Timing Affects Your Total Cost

Here’s something most articles don’t address clearly: when you enroll affects your premium, not just your eligibility. Medigap premiums are typically based on your age at enrollment. The younger you are when you lock in a plan, the lower your starting premium. That difference compounds over years of coverage.

Look at how premiums typically compare by age for a Plan G in Ohio:

Age at Enrollment	Estimated Monthly Premium (Plan G, Ohio)	Estimated 10-Year Total Cost
65	$115	$13,800+
67	$135	$16,200+
70	$165	$19,800+
72	$190	$22,800+

These are illustrative figures based on typical insurer pricing in Ohio as of 2026. Actual premiums vary by insurer and county. But the pattern holds everywhere: waiting costs you more per month, and that gap adds up quickly.

That said, I want to give honest advice for people who are still working with good employer coverage past 65. If your employer plan has low cost-sharing and solid coverage, there’s a real argument for staying on it and waiting to start Medigap when you actually retire. You’re not losing your Medigap window as long as you have creditable coverage through your employer and you enroll in Part B when that ends. Just don’t let it drag on past your Part B enrollment window and into a situation where you’re trying to get underwritten at 74 with a complicated health history.

Bottom Line

For most people, the best time to enroll in a Medicare supplement plan is the month you turn 65 and enroll in Part B, and you should treat that six-month window like the limited resource it is. If you’re still working with good employer coverage, enroll in Medigap as soon as you retire and sign up for Part B. Don’t wait to see how your health goes, because by the time you know you need coverage, it may be too late to get it at a standard rate, or at all.

Frequently Asked Questions

Can I be denied Medigap coverage if I apply during my open enrollment period?

No. During your six-month Medigap Open Enrollment Period, insurers are legally required to sell you any plan they offer at standard rates, regardless of your health history. Denials and medical underwriting only apply if you apply outside of that window without a qualifying special enrollment situation.

What happens if I miss my Medigap open enrollment window?

In most states, you’ll have to go through medical underwriting when you apply. Insurers can reject your application, charge you higher premiums, or impose waiting periods on pre-existing conditions. A handful of states have stronger protections, so check your state’s specific rules if you’ve already missed your window.

Is there a penalty for enrolling in Medigap late, like there is for Part B?

No, there’s no federal late-enrollment penalty for Medigap the way there is for Part B or Part D. But the practical consequence is that you lose guaranteed issue protections, which can be far more costly than a percentage-based penalty. You might not be able to get the plan you want at all.

If I’m 68 and just retired, is it too late to get a Medigap plan?

Not necessarily. If you’re enrolling in Part B now because you just left employer coverage, your Medigap open enrollment window opens now and runs for six months. You’re protected under guaranteed issue rules for that window regardless of your age. Get your Part B enrollment confirmed and then shop for a supplement plan right away.

What Medicare Actually Pays for Home Health Care (And Where the Gaps Are)

Home health care is one of those benefits people think they understand until they actually need it, and then the bill shows up. Here’s what you need to know upfront: Original Medicare Part A and Part B together cover a meaningful chunk of skilled home health care, but Medigap’s role in filling the remaining costs is more limited than most people expect.

Under Original Medicare, you can receive covered home health care services if you meet four conditions: you’re homebound, a doctor certifies that you need skilled care, a Medicare-certified home health agency provides the care, and the care itself qualifies as skilled (meaning skilled nursing, physical therapy, speech therapy, or occupational therapy). If those boxes are checked, Medicare pays 100% of the approved costs for covered services, with one exception: you pay 20% coinsurance for Medicare-approved durable medical equipment (DME) that comes along with the home health care plan.

So where does Medigap come in? That 20% DME coinsurance is one of the few legitimate home health care costs that a Medicare supplement plan can actually help cover. Beyond that, most of the “gaps” people worry about with home health care aren’t gaps in the Medicare supplement sense. They’re gaps in what Medicare covers at all, and no Medigap plan fixes that.

This distinction matters enormously. I’ve watched people buy a Medigap plan assuming it would protect them from home health care costs they were imagining, only to find out later that the situation they feared, like needing a home health aide for personal care or help with daily activities, isn’t covered by Medicare or Medigap in the first place.

The Big Misconception: Custodial Care Versus Skilled Care

This is the mistake I see most often, and it’s worth spending real time on it because the confusion can leave people completely unprotected when they need help most.

Medicare, and by extension any Medigap plan, does not cover custodial care. Custodial care means assistance with daily living activities like bathing, dressing, eating, getting around the house, and personal hygiene. That’s the type of home-based care that most people actually picture when they think “I want to stay in my home as I age.” That’s not what Medicare’s home health benefit covers.

Medicare’s home health benefit covers skilled care. A nurse coming to your home to administer IV medications or monitor a wound after surgery? That’s skilled care. Medicare covers it. A home health aide helping you bathe three times a week because you have severe arthritis and can’t manage it yourself? That’s custodial. Medicare won’t touch it, and neither will any Medigap plan on the market.

The rule exists because Medicare was designed as health insurance, not long-term care coverage. Congress drew a hard line at skilled medical services. The system isn’t broken, it’s just doing exactly what it was designed to do. But if nobody explains that to you, you can spend years paying Medigap premiums feeling protected, and then discover the one situation you were worried about was never in the coverage territory to begin with.

If custodial home care is what you’re concerned about, you need to look at long-term care insurance or, in some states, Medicaid planning. That’s a separate conversation, but it’s the honest answer.

How Medigap Plans Actually Cover Home Health Care Costs

Let’s get specific about which Medigap plans help with the costs that do legitimately arise from home health care under Medicare, and by how much.

For skilled home health care, the main out-of-pocket exposure you have under Original Medicare is that 20% DME coinsurance. Plans that cover Part B coinsurance will cover that cost. The other area where Medigap matters for home health care is if your skilled home health services happen to follow a hospital stay and interact with Part A costs, like the Part A deductible, which is $1,676 per benefit period in 2026.

Medigap Plan	Part A Deductible	Part B Coinsurance (incl. DME)	Skilled Nursing Facility Coinsurance	Part B Deductible
Plan G	100% covered	100% covered	100% covered	Not covered
Plan N	100% covered	Covered (copays may apply for office visits)	100% covered	Not covered
Plan F	100% covered	100% covered	100% covered	100% covered
Plan K	50% covered	50% covered	50% covered	Not covered
Plan L	75% covered	75% covered	75% covered	Not covered

Plan F covers the most, including the 2026 Part B deductible of $257, but it’s only available to people who were eligible for Medicare before January 1, 2020. If you aged into Medicare after that date, Plan G is your strongest option. For most people turning 65 today, Plan G is the practical gold standard.

Plan N can work well too, particularly if you’re in good health and don’t anticipate frequent doctor visits. The trade-off is that you’ll face up to $20 copays for some office visits and $50 for emergency room visits that don’t lead to inpatient admission. For home health care specifically, Plan N covers the Part B coinsurance the same way Plan G does, so the DME coinsurance situation is handled equally well by both.

When Home Health Care Intersects With a Hospital or Skilled Nursing Stay

This is where Medigap’s value for home health care situations becomes much clearer. Skilled home health care often follows a hospitalization or a skilled nursing facility (SNF) stay, and those events carry significant costs that Medigap is designed to cover.

Take a 72-year-old woman in Florida who has a hip replacement, spends five days in the hospital, transfers to a skilled nursing facility for two weeks of rehab, and then comes home with a Medicare-certified home health agency providing physical therapy and wound care for six weeks. Her cost exposure without Medigap would include the $1,676 Part A deductible for the hospital stay, SNF coinsurance of $209.50 per day for days 21 through 100 in 2026, and the 20% coinsurance on any DME she receives at home.

With Plan G, all of that is covered. That’s real money, and that’s where you actually see the value of a Medigap plan in a home health care scenario. The home health care itself isn’t the line item that kills you. It’s the hospital and SNF costs that got you there.

Which brings us to a point I want to make directly: if someone tries to sell you a Medigap plan by heavily emphasizing home health care coverage as a standalone benefit, that’s a red flag. A good plan covers the hospital and medical costs surrounding home health care. The home health care benefit under Medicare, when it applies, is already largely covered at 100% by Medicare itself.

What Home Health Care Actually Costs Out of Pocket Without Medigap

If you’re trying to decide whether Medigap is worth it with home health care in mind, you need real numbers, not abstractions.

For Medicare-covered skilled home health care services themselves, your out-of-pocket cost under Original Medicare is typically zero for the skilled services and 20% for any DME. If your home health care includes durable medical equipment like a wheelchair, hospital bed, or oxygen equipment, that 20% can add up. A power wheelchair approved by Medicare might cost $3,000 to $6,000, meaning a $600 to $1,200 bill just for that item alone.

Plan G in 2026 typically runs $100 to $200 per month for a 65-year-old, depending on your state and insurer. A 70-year-old will pay more, often $150 to $250 per month. That coverage goes well beyond home health care DME, obviously, but if you’re trying to justify the premium, consider that even one significant hospital stay triggering a $1,676 Part A deductible more than pays for a year of premiums.

For custodial home care, which is not covered by Medicare or Medigap, home health aides typically cost $25 to $35 per hour in most markets as of 2026. If someone needs 20 hours a week of aide help, that’s $2,000 to $2,800 per month out of pocket. No Medigap plan helps with that. Long-term care insurance or personal savings is your only protection.

Bottom Line

For most people, Plan G is the right Medigap choice, and it does a solid job covering the real costs that surround home health care, particularly the hospital and skilled nursing facility expenses that typically precede it. Don’t buy Medigap because you think it will cover custodial home care or personal aide services, because it won’t, and no plan will. If that’s your concern, talk to a financial advisor about long-term care planning before you do anything else.

Frequently Asked Questions

Does Medigap cover home health aides who help with bathing and dressing?

No. Neither Medicare nor any Medigap plan covers custodial or personal care services like help with bathing, dressing, or daily activities. That’s considered custodial care, not skilled medical care. Medicare’s home health benefit only covers skilled nursing and therapy services. If you need coverage for personal care aides, you’re looking at long-term care insurance, Medicaid (if you qualify), or paying out of pocket.

If Medicare covers home health care at 100%, why do I need Medigap?

Medicare covers the skilled home health services themselves at 100%, but it doesn’t cover everything connected to that care. The 20% coinsurance on durable medical equipment is one gap. More significantly, Medigap protects you from the hospital and skilled nursing costs that often lead to needing home health care in the first place. Those costs can easily exceed $5,000 in a single benefit period without coverage.

How many home health visits does Medicare actually cover?

There’s no set cap on the number of visits. Medicare covers skilled home health care for as long as you meet the eligibility criteria: you’re homebound, you need skilled care, a doctor certifies it, and a Medicare-certified agency provides it. The benefit period continues as long as these conditions are met. The practical limit is that Medicare can and does audit home health claims, and agencies must document ongoing medical necessity carefully.

My neighbor said her Medigap plan covered her home health care completely. Is that true?

Probably, but not for the reasons she thinks. If Medicare approved and covered her skilled home health services at 100%, and Medigap covered her Part A deductible and any DME coinsurance, then yes, her total out-of-pocket could have been zero. That’s a realistic outcome for someone with good coverage. But what was actually working there was Medicare’s home health benefit doing the heavy lifting, with Medigap filling the remaining edges. If her situation had involved custodial care, the story would have been very different.

Yes, Most Medigap Plans Cover Hospital Copays — But Not All of Them

Most Medicare supplement plans will cover your hospital stay copays, and the better ones cover them completely. That’s actually one of the biggest reasons people buy Medigap in the first place. But the details matter more than you’d think, and the wrong plan can leave you stuck with bills you weren’t expecting.

Here’s how it works. Original Medicare (Parts A and B) covers hospital stays, but it doesn’t pay 100% of everything. There are deductibles, daily copays, and lifetime limits built into the structure. Medigap exists to fill those gaps. Depending on which plan you choose, it fills them partially or almost completely.

I’ve talked to a lot of people who assumed their Medigap plan “covered everything hospital-related.” Some of them were right. Others were in for a surprise when they got the bill. Let me break down exactly what you’re looking at.

How Medicare Structures Hospital Costs (And Where the Gaps Are)

Before you can understand what Medigap covers, you need to understand what Medicare charges. Part A is your hospital insurance, and it doesn’t work like a simple copay system. It uses something called benefit periods, which trips people up constantly.

A benefit period starts the day you’re admitted to a hospital and ends after you’ve been out of the hospital (or a skilled nursing facility) for 60 consecutive days. Each benefit period has its own deductible and its own set of daily copays for longer stays.

For 2026, here’s what Part A actually charges you:

Length of Hospital Stay	What Medicare Charges You
Days 1-60	$1,676 deductible per benefit period (no daily copay)
Days 61-90	$419 per day
Days 91-150 (lifetime reserve days)	$838 per day
Beyond 150 days	You pay 100% of all costs

Most people never stay past day 60 in a single hospitalization, so the daily copays for days 61-90 don’t come up often. But that 2026 Part A deductible of $1,676 hits every single benefit period, not just once a year. If you’re hospitalized twice in a year with more than 60 days between stays, you owe that deductible twice. That’s the part that genuinely catches people off guard.

Part B has its own deductible for outpatient services. The 2026 Part B deductible is $257, and after that Medicare covers 80% of approved outpatient costs. You’re responsible for the remaining 20% with no cap unless you have Medigap.

Which Medigap Plans Actually Cover Hospital Copays

This is where you need to pay attention, because not every Medigap plan covers the same things. Let me give you the honest breakdown.

Medigap Plan	Part A Deductible	Part A Daily Copays (Days 61-90)	Part B Coinsurance (20%)	Part B Deductible
Plan G	Covered 100%	Covered 100%	Covered 100%	Not covered
Plan N	Covered 100%	Covered 100%	Covered (with copays up to $20 office / $50 ER)	Not covered
Plan F	Covered 100%	Covered 100%	Covered 100%	Covered 100%
Plan K	50% covered	50% covered	50% covered	Not covered
Plan L	75% covered	75% covered	75% covered	Not covered
Plan A	Not covered	Covered 100%	Covered 100%	Not covered

Plan F was the gold standard for years, but it’s no longer available to people who became eligible for Medicare after January 1, 2020. If you turned 65 before 2020, you can still buy it. If you didn’t, Plan G is now the most complete option available to you, and honestly, it’s the one I’d recommend for most people.

Plan G covers the 2026 Part A deductible of $1,676, all daily hospital copays, and the Part B 20% coinsurance. The only thing it doesn’t cover is the 2026 Part B deductible of $257. That’s $257 once a year out of pocket. After that, you’re essentially protected from any major cost exposure for both hospital stays and outpatient care.

Plan N is a solid second option if you’re generally healthy and want lower monthly premiums. You’ll pay a copay of up to $20 for office visits and up to $50 for emergency room visits that don’t result in an inpatient admission. Hospital stays themselves are still well covered under Plan N.

The Misconception That Trips Up a Lot of People

Here’s the mistake I see more than any other: people confuse “hospital stay” with “inpatient hospital stay.” They’re not always the same thing, and Medicare’s rules on this are genuinely maddening.

When you’re admitted to a hospital, you might be placed under “observation status” instead of being formally admitted as an inpatient. This happens more than you’d think, sometimes even when you’re staying overnight. Under observation status, you’re technically an outpatient. That means Part B covers your care, not Part A, and the cost structure is completely different.

Why does this matter? A few reasons. First, your Medigap plan’s hospital coverage is tied to Part A. If you’re under observation, Part A isn’t paying, so the benefit works differently. Second, and this is the one that really stings, if you go from the hospital to a skilled nursing facility under observation status, Medicare won’t cover your skilled nursing stay at all. Part A requires a three-day qualifying inpatient stay before it kicks in for skilled nursing. Observation days don’t count.

In my experience, people find out about this rule after the fact, when they’re already in the skilled nursing facility looking at a bill for thousands of dollars. The hospital generally won’t tell you proactively whether you’re inpatient or under observation. You have to ask. Specifically ask: “Am I formally admitted as an inpatient, or am I under observation status?” Get a clear answer in writing if you can.

This isn’t a Medigap problem, it’s a Medicare problem. But knowing it exists means you can ask the right questions and protect yourself.

What Plan G Actually Costs and Whether It’s Worth It

Plan G premiums vary significantly depending on your age, state, and the insurance company. At age 65, you’re typically looking at somewhere between $100 and $200 per month. A 65-year-old in Ohio might pay around $115 to $145 per month through a reputable carrier. In a higher-cost state like New York, that same person could pay $250 or more because New York has community rating rules that drive prices up.

Is it worth it? For most people, yes. Here’s the math for a simple scenario: if you have one hospital admission in a year, you’ve already gotten $1,676 worth of coverage from Plan G just on the Part A deductible alone. Add in any outpatient care, specialist visits, or procedures where Medicare’s 20% adds up, and Plan G’s value compounds quickly.

The people who might not need Plan G are those who are genuinely healthy, rarely see doctors, and have significant savings they’re comfortable using to cover unexpected medical costs. For those folks, Plan N or even a high-deductible Plan G can make sense. But if you’re asking me whether the average 67-year-old should buy protection against hospital copays, the answer is yes. The risk of one bad hospitalization without it is too high to justify saving $80 a month on premiums.

One more thing worth mentioning: if you’re already past your initial enrollment window, you may face medical underwriting to qualify for Plan G, which means insurers can deny you or charge more based on your health history. The best time to buy is when you first become eligible for Medicare, when you have guaranteed issue rights and can’t be turned down.

Bottom Line

Plan G is the right call for most people who want real protection against hospital stay costs. It covers the Part A deductible per benefit period, all daily hospital copays, and the Part B 20% coinsurance, leaving only the $257 annual Part B deductible on your plate. Buy it when you first enroll in Medicare, compare prices from at least three carriers in your state, and ask your hospital directly whether you’re admitted as an inpatient or under observation any time you end up in the emergency room.

Frequently Asked Questions

Does Medigap cover the Part A deductible every time I’m hospitalized?

Yes, if you have Plan G, Plan F, or Plan N, your Medigap plan covers the Part A deductible each time a new benefit period begins. Since a new benefit period starts after you’ve been out of the hospital for 60 consecutive days, you could theoretically owe this deductible more than once in a year if you have multiple hospitalizations with 60+ days between them. That’s exactly why having coverage for it matters.

Will Medigap cover me for a long hospital stay that goes past 60 days?

Yes. Plan G, Plan F, and Plan N all cover the daily copays for days 61 through 90, which are $419 per day in 2026. They also cover the lifetime reserve days (days 91-150), which cost $838 per day without coverage. Stays beyond 150 days are not covered by Medicare at all, and most Medigap plans don’t cover that either, though some plans offer a limited daily hospital benefit for extended stays.

I’m on a Medicare Advantage plan. Does any of this apply to me?

No. Medigap plans only work with Original Medicare. If you’re on Medicare Advantage, you can’t use a Medigap plan. Your hospital costs under Medicare Advantage depend entirely on your specific plan’s copays and out-of-pocket maximums, which vary by insurer and plan. If you want the Medigap protections described here, you’d need to switch back to Original Medicare first.

Can I buy Plan G if I’m already sick or have pre-existing conditions?

It depends on when you’re applying. During your initial Medigap open enrollment period, which starts when you’re 65 and enrolled in Part B, you have guaranteed issue rights and can’t be turned down for any plan. Outside of that window, most states allow insurers to use medical underwriting, meaning they can decline you or charge higher premiums based on your health. A few states, including New York, Connecticut, and Massachusetts, have stronger consumer protections that allow year-round enrollment regardless of health status.

The Short Answer: Medigap Follows Medicare’s Lead

Medicare supplement insurance doesn’t cover preventive care screenings on its own. It covers your cost-sharing after Medicare Part B pays its share. That distinction sounds small, but it changes everything about how you plan for your healthcare costs.

Here’s the thing. Medicare Part B already covers a genuinely impressive list of preventive screenings at no cost to you, provided certain conditions are met. When those screenings are billed correctly and you’ve met your deductible requirements, Medigap steps in to handle whatever cost-sharing remains. The result is that many people on a strong Medigap plan like Plan G end up paying nothing out of pocket for covered preventive services.

But “many people” is not “all people,” and the exceptions matter a lot. I’ve seen retirees get blindsided by bills they assumed Medigap would handle, and in almost every case, the confusion came down to one of three things: a service that wasn’t technically “preventive,” a provider who didn’t accept Medicare assignment, or a screening that crossed into diagnostic territory. We’ll cover all of it.

What Medicare Part B Actually Covers for Prevention

Before you can understand what Medigap does, you need to know what Medicare does. Part B covers a wide range of preventive screenings, and for most of them, your cost-sharing is zero as long as the visit is coded and billed correctly.

Here are some of the key preventive services Part B covers at 100% with no cost to you:

• Annual Wellness Visit (AWV)
• Mammograms (screening, once every 12 months)
• Colorectal cancer screenings (colonoscopies for average-risk patients, once every 10 years)
• Pap smears and pelvic exams (once every 24 months for average-risk women)
• Prostate cancer screening (PSA test, once every 12 months)
• Lung cancer screening CT scans (for high-risk patients, once per year)
• Bone density tests (for qualifying patients, once every 24 months)
• Diabetes screenings (up to two per year for at-risk patients)
• Cardiovascular disease screenings (cholesterol, once every 5 years)
• Depression screening (once per year)
• HIV, hepatitis B, and hepatitis C screenings for qualifying patients
• Abdominal aortic aneurysm screening (once, for qualifying smokers)

For all of these, when billed as preventive, Medicare pays 100% and there’s no Part B deductible applied. That’s the law. And because there’s no cost-sharing left over, Medigap has nothing to pay. Which is actually fine, because you owe nothing.

The 2026 Part B deductible is $257. It does not apply to these preventive screenings when they’re billed correctly. Keep that number in mind, because it becomes relevant the moment a service stops being “purely preventive.”

The Diagnostic Trap: The Mistake That Costs People Real Money

This is the section I wish someone had written for my readers years ago, because I’ve seen this mistake happen over and over.

You go in for your free screening colonoscopy. Your doctor finds a polyp and removes it. You get the bill. Now you owe money. How did that happen?

When a preventive screening produces a finding that requires treatment during the same visit, the billing often changes. The procedure gets reclassified, partially or fully, as diagnostic or therapeutic. At that point, Medicare’s 100% preventive coverage no longer applies to the whole bill. You may be on the hook for 20% of the Medicare-approved amount for part of the service.

This is not a billing error. It’s just how the rules work. Medicare treats screenings and treatment as different things, even when they happen in the same room on the same day.

Here’s where Medigap earns its keep. If you have Plan G, your plan would typically cover that 20% coinsurance after you’ve met the 2026 Part B deductible of $257. If you haven’t met your deductible yet that year, you’d owe the deductible first, then Medigap covers the rest. Plan F (for those grandfathered in before January 1, 2020) would cover the deductible too.

So while Medigap doesn’t technically “cover preventive screenings,” it does protect you from the financial fallout when a screening turns into something more. That’s actually one of the best arguments for having a strong Medigap plan if you’re at the age where screenings regularly turn up findings worth investigating.

How the Main Medigap Plans Stack Up on Preventive-Related Costs

Not all Medigap plans handle cost-sharing the same way. Here’s a practical breakdown of how the most popular plans handle the costs you might face when a screening produces cost-sharing:

Medigap Plan	Covers Part B Deductible ($257 in 2026)?	Covers Part B 20% Coinsurance?	Best For
Plan G	No	Yes	Most new enrollees (available post-2020)
Plan F	Yes	Yes	Grandfathered enrollees only (pre-2020)
Plan N	No	Yes (with some copays)	Healthier people who rarely see specialists
Plan K	No	50% (not full coverage)	Lower-premium seekers willing to share more risk
Plan L	No	75% (not full coverage)	Middle-ground option with lower premiums

My honest take: for most people I work with, Plan G is the right call. At age 65 in 2026, you’re typically looking at $100 to $200 per month depending on your state and which insurer you use. Ohio, for example, tends to run toward the lower end of that range. You pay the $257 deductible once a year and then you’re fully covered for Medicare-approved costs. That’s a simple, predictable structure that most people find worth the premium.

Plan N is worth considering if you’re healthy and want a lower premium, but you’ll face copays of up to $20 for office visits and $50 for emergency room visits that don’t result in inpatient admission. For screenings that turn diagnostic, those copays can add up.

What Medigap Won’t Help With, Even on a Premium Plan

There are real gaps in preventive care coverage that no Medigap plan fixes, and I’d rather tell you about them now than have you find out the hard way.

Services Medicare doesn’t cover at all. Medigap can only cover your share of Medicare-approved costs. If Medicare denies a claim entirely, Medigap won’t pay either. Routine dental, vision, and hearing are the big three. A hearing screening at your annual wellness visit might be included, but hearing aids and most dental work are completely outside the Medicare and Medigap system. You’d need a separate plan for those.

Out-of-network providers who don’t accept Medicare assignment. If a provider doesn’t accept Medicare assignment, they can charge up to 15% more than the Medicare-approved amount. Medigap plans generally don’t cover this “excess charge” unless you have Plan F or Plan G, which do cover excess charges. This is another reason Plan G is worth the premium in my opinion.

Prescription drugs. Preventive medications, like statins recommended after a cardiovascular screening or medications prescribed based on a diabetes screening result, aren’t covered by Medigap. You need Part D for that. Don’t forget to enroll in a Part D plan even if you’re not currently taking prescriptions. The late enrollment penalty is unforgiving.

Screenings not yet approved by the USPSTF. Medicare largely follows the U.S. Preventive Services Task Force recommendations. If a screening isn’t on that list, Medicare probably won’t cover it. Your doctor might recommend it, but that doesn’t mean Medicare will pay for it.

Bottom Line

For the vast majority of Medicare beneficiaries, a plan like Medigap Plan G combined with Medicare Part B gives you strong protection on preventive care. Most screenings are free under Part B, and when a screening leads to a finding that creates cost-sharing, Plan G handles that 20% coinsurance after your $257 annual deductible. The one mistake to avoid is assuming that “free preventive screening” means “free no matter what happens during that appointment.” It doesn’t, and that’s exactly the kind of gap Medigap is built to catch.

Frequently Asked Questions

Does Medigap cover the Annual Wellness Visit?

The Annual Wellness Visit is covered at 100% by Medicare Part B with no cost-sharing, so there’s nothing left for Medigap to cover. You won’t get a bill for it. The catch is that if your doctor addresses other health concerns during the same visit and bills them separately, that additional portion may trigger cost-sharing that Medigap would then cover.

Will my colonoscopy be free if I have Medigap?

A routine screening colonoscopy with no findings is free under Medicare Part B. If a polyp is found and removed during the same procedure, the billing often shifts and you may owe cost-sharing. If you have Plan G, Medigap would cover that coinsurance after your annual deductible. Without Medigap, that 20% coinsurance can easily be several hundred dollars.

Does Medigap cover preventive care differently than regular medical care?

No. Medigap doesn’t distinguish between preventive and non-preventive care. It covers your cost-sharing on Medicare-approved services regardless of the type of care. The reason preventive care feels “free” is that Medicare waives the cost-sharing on those services, leaving nothing for Medigap to pay. When cost-sharing exists, Medigap covers it based on your plan’s benefits.

I just turned 65. Should I get Medigap before I have any screenings scheduled?

Yes, and the timing matters more than people realize. Your Medigap Open Enrollment Period starts the month you’re both 65 and enrolled in Part B. During that window, no insurer can deny you coverage or charge you more based on health history. If you wait until after a screening turns up a significant finding, you could face medical underwriting and potentially be denied or charged much higher premiums. Enroll during that window even if you feel perfectly healthy.

Here’s the Brutal Truth About Medigap and Hearing

No Medicare supplement plan covers hearing aids or hearing exams. Not Plan G. Not Plan F. Not any of them. And I want you to hear that clearly before you spend months comparing Medigap premiums thinking your hearing costs will be handled once you pick the right letter.

This is one of the most common gaps people discover after they’ve already enrolled, usually when they’re sitting in an audiologist’s office being handed a bill for $4,000 or $5,000 for a pair of hearing aids. By then, there’s nothing you can do except pay it.

What Medigap actually does is fill the gaps in original Medicare, meaning it covers things like your Part A hospital deductible (which is $1,676 per benefit period in 2026), your Part B coinsurance after you’ve met the annual deductible ($257 in 2026), and a handful of other costs that traditional Medicare leaves you holding. It doesn’t create new benefits. It only pays what Medicare would have paid if you had less cost-sharing. Since Medicare doesn’t cover hearing aids or routine hearing exams at all, Medigap has nothing to fill in.

That’s not a flaw in your specific plan. It’s how the entire system is structured.

What Original Medicare Actually Covers for Hearing

Original Medicare is stingy when it comes to hearing, and it has been for decades. Here’s where the line sits.

Medicare Part B will pay for a diagnostic hearing exam if your doctor orders it to diagnose a medical condition, not to fit you for a hearing aid. So if you’re having balance problems and your physician refers you to an audiologist to rule out inner ear damage, that exam is covered under Part B (after your deductible, at 80/20 cost-sharing). Medigap then kicks in to cover the 20% you’d owe.

But a routine hearing exam, the kind where you go in to see how your hearing has changed and whether you might benefit from hearing aids, is not covered. Medicare considers that preventive or elective. Same goes for the hearing aids themselves. Medicare explicitly excludes hearing aids and the exams for fitting them from Part B coverage. This exclusion has been in place since Medicare was created in 1965, and despite repeated efforts in Congress to change it, it’s still the rule today.

So when someone tells you that Medigap “covers everything Medicare covers,” that’s technically true. The problem is what Medicare doesn’t cover.

The Common Mistake That Costs People Thousands

I’ve seen this play out more times than I can count: someone in their late 60s, maybe a 68-year-old in North Carolina, picks up a Plan G because they want solid coverage. They pay around $140 to $170 per month in premiums, feel good about their coverage, and assume they’re protected. A year later, they get their first real hearing test as a senior, learn they need aids, and walk out with a $3,500 to $6,000 expense they had no idea was coming.

The mistake isn’t buying Plan G. Plan G is a genuinely good plan for most people. The mistake is assuming that “comprehensive” coverage means all healthcare costs. Medigap covers hospital and medical costs under Parts A and B. It doesn’t touch vision, dental, or hearing, which Medicare calls “routine” and excludes entirely.

Some people make a second, related mistake: they hear that Medicare Advantage plans often include some hearing benefits, and they think switching to a Medigap plan means giving that up permanently. That’s worth thinking about before you enroll. Once you’ve been on Medigap for a while, getting back into a Medicare Advantage plan is possible, but getting back onto a different Medigap plan may require medical underwriting in most states. You could be locked out of certain plans if your health has changed.

Your Real Options for Hearing Aid Coverage

Since Medigap won’t help you here, let’s talk about what actually will.

Medicare Advantage plans: Many Medicare Advantage plans include hearing benefits. The quality and generosity of those benefits varies wildly, from $500 per year toward hearing aids to full coverage of certain models. The tradeoff is that you give up the predictability of Medigap. Advantage plans use networks, prior authorizations, and variable cost-sharing. For people with significant ongoing medical needs, that tradeoff is often not worth it just to get hearing coverage. But if you’re generally healthy and primarily worried about hearing costs, it’s a real option to consider.

Standalone hearing benefit plans: Companies like TruHearing, Hearing Care Solutions, and a few others offer standalone discount programs or supplemental insurance specifically for hearing. These aren’t insurance in the traditional sense, but they negotiate discounted rates with audiologists and hearing aid providers. You pay a modest monthly fee or annual membership and get access to reduced pricing. A pair of hearing aids that retails for $5,000 might cost you $2,000 through one of these programs.

Direct-to-consumer hearing aids: Since 2022, the FDA has allowed over-the-counter (OTC) hearing aids for adults with mild to moderate hearing loss. Brands like Jabra Enhance, Lexie, and Sony sell devices for $300 to $1,600 without a prescription or audiologist visit. These won’t work for everyone, particularly those with severe hearing loss or complex fitting needs. But for the right person, they’re a legitimate and dramatically cheaper option.

Veterans benefits: If you’re a veteran, the VA may cover hearing aids and audiology services at no cost. This is one of the most underused benefits I see among veterans in their 60s and 70s. If you qualify for VA healthcare, check what your specific eligibility level covers before you pay a dime out of pocket.

Coverage Option	Covers Hearing Aids?	Covers Hearing Exams?	Typical Cost to You
Original Medicare (Part B)	No	Only if medically necessary	Full cost out of pocket
Medicare Supplement (Medigap)	No	Only if Part B covers the exam	No additional help for hearing
Medicare Advantage	Often yes, with limits	Often yes	Varies; may have network restrictions
Standalone hearing plans	Discounted, not full coverage	Discounted	$20-$50/month or annual fee
OTC hearing aids	Self-purchase only	No exam required	$300-$1,600 one-time
VA benefits	Yes (if eligible)	Yes (if eligible)	Little to no cost

How to Factor Hearing Costs Into Your Medicare Decision

If you’re still deciding between original Medicare with a Medigap plan versus Medicare Advantage, hearing is one legitimate factor to weigh. But only one. Don’t let it be the deciding factor if your overall health situation points clearly in one direction.

Here’s how I think about it. If you already know you have significant hearing loss, or you’ve been told you’ll need hearing aids soon, that changes your math. A Medicare Advantage plan with $1,500 per year in hearing benefits might save you real money. Add up what you’d spend on Medigap premiums versus what you’d spend on Advantage premiums and out-of-pocket medical costs, then factor in the hearing benefit. For a 65-year-old in Ohio who’s relatively healthy, the numbers can actually favor Advantage in this scenario.

That said, if you have a serious chronic condition, see multiple specialists regularly, or want the freedom to see any doctor in the country without referrals or networks, Medigap is still probably the better choice overall. You can always add a standalone hearing discount program for a modest monthly fee and still come out ahead on total healthcare costs.

The key is to build your coverage decision around your whole health picture, not just one line item. Hearing is important. So is not getting stuck with a $15,000 hospital bill because your Advantage plan denied a prior authorization.

Bottom Line

Medicare supplement plans don’t cover hearing aids or routine hearing exams, period, and no amount of comparing plan letters will change that. If hearing coverage matters to you, your best path is either a Medicare Advantage plan with a meaningful hearing benefit, or a Medigap plan paired with a standalone hearing discount program. For most people who are otherwise well-served by Medigap, I’d go with the latter: keep Plan G for the predictability it gives you on medical costs, and handle hearing separately with an OTC device or a discount program rather than overhauling your entire Medicare setup.

Frequently Asked Questions

Does Plan G cover hearing aids?

No. Plan G is one of the best Medigap plans available, but it doesn’t cover hearing aids or routine hearing exams. No Medigap plan does. Plan G covers costs that original Medicare covers, and Medicare doesn’t cover hearing aids at all.

Will Medicare pay for a hearing exam if my doctor orders it?

Only if it’s medically necessary, meaning your doctor is ordering the exam to diagnose or treat a medical condition, not to evaluate you for a hearing aid. If your doctor orders a diagnostic audiology exam to investigate dizziness, tinnitus, or suspected nerve damage, Medicare Part B will cover 80% after your deductible. Your Medigap plan then covers the remaining 20%. A routine hearing test to check how your hearing is doing does not qualify.

Can I add hearing coverage to my Medigap plan?

Not directly. Medigap plans are standardized by federal law, and hearing coverage isn’t one of the benefits included in any plan letter. What you can do is add a separate, standalone hearing benefit plan or discount program alongside your Medigap plan. These aren’t part of Medicare, but they can significantly reduce what you pay for hearing aids and exams.

Are over-the-counter hearing aids worth it?

For mild to moderate hearing loss, yes, they can be worth it. Since the FDA opened up the OTC market in 2022, quality has improved and prices have dropped considerably. Brands like Jabra Enhance and Lexie offer real technology at a fraction of what prescription aids cost. The caveat is that they work best when your hearing loss is not severe and you’re comfortable self-adjusting the device through an app. If you’ve been told you have significant or complex hearing loss, you’ll likely still want to work with an audiologist.

The Short Answer: Medigap Follows Medicare’s Lead on Chiropractic

Medicare supplement plans cover chiropractic care the same way they cover everything else: they pick up costs that Original Medicare leaves behind. The catch is that Medicare itself covers almost nothing when it comes to chiropractic. So before you assume your Medigap plan is going to handle your chiropractor bills, you need to understand what Medicare Part B actually pays for first.

Here’s the thing. A lot of people buy a Plan G or Plan N, feel confident they’re covered, and then get hit with a $100+ bill after a few chiropractic visits. They’re confused and frustrated. I’ve seen this happen repeatedly, and it’s almost always because nobody explained the underlying Medicare rules clearly before they enrolled.

Let me fix that right now.

What Medicare Part B Actually Covers for Chiropractic

Medicare Part B covers exactly one chiropractic service: manual manipulation of the spine to correct a subluxation. That’s it. If your chiropractor is physically adjusting your spine to correct a vertebral subluxation that’s documented in your medical record, Medicare Part B will generally cover 80% of the Medicare-approved amount after you’ve met your 2026 Part B deductible of $257.

That sounds reasonable until you read the fine print. Medicare will not cover:

• X-rays taken by your chiropractor
• Massage therapy performed at a chiropractic office
• Acupuncture (even if offered at the same clinic)
• Therapeutic exercises or stretching instruction
• Ultrasound therapy or electrical stimulation
• Maintenance care once you’ve plateaued in improvement

That last point deserves its own sentence: maintenance care. This is where most people get blindsided. If your chiropractor determines that you’ve reached your maximum therapeutic benefit but you want to keep coming in regularly to maintain that level of function, Medicare considers those visits maintenance care and will not pay for them. Not one cent.

The reason Medicare draws this line is baked into how the program defines covered services. Medicare Part B is designed to pay for treatment that improves or restores function. Once you’re at your best and the visits are just keeping you there, Medicare says that’s not medically necessary under their definition. You can disagree with that logic, and plenty of people do, but that’s the rule you’re working with.

So when your chiropractor hands you an Advance Beneficiary Notice (ABN) before a visit, pay attention. That form means they think Medicare probably won’t cover that service, which also means your Medigap plan won’t be covering it either.

How Medigap Fills In the Gaps (And Where It Can’t Help)

Once you understand what Medicare covers, how Medigap works for chiropractic becomes simple to explain. Medigap covers your share of Medicare-approved costs. For covered chiropractic adjustments, that means:

Plan Type	Part B Deductible	Part B Coinsurance (20%)	Excess Charges
Plan G	You pay ($257 in 2026)	Covered	Covered
Plan N	You pay ($257 in 2026)	Covered (up to $20 copay per visit)	Not covered
Plan F (pre-2020 enrollees only)	Covered	Covered	Covered

Take a practical example. Say you’re a 67-year-old in Ohio with Plan G. Your chiropractor performs a covered spinal manipulation, and Medicare approves the claim. After you’ve met your $257 Part B deductible for 2026, your Plan G covers the 20% coinsurance. Your out-of-pocket cost for that approved visit? Zero, assuming you’ve already met the deductible.

But here’s where it breaks down. If your chiropractor bills Medicare for a visit that Medicare determines is maintenance care and denies, your Medigap plan has nothing to work with. Medicare denied it. There’s no approved cost for Medigap to cover. You’re paying the full bill out of pocket, and your Medigap plan is completely irrelevant to that transaction.

That’s not a bug in the system. That’s exactly how it’s designed to work.

The Mistake I See People Make All the Time

The most common and expensive misconception I see is people assuming that because they have a “good” Medigap plan, their chiropractic bills are basically handled. They buy Plan G, they feel protected, and they stop reading the details. Then they start going to their chiropractor two or three times a week for an ongoing back condition and assume the bills are going to be minimal.

They’re not.

If those visits are covered by Medicare as active treatment, you’re probably fine after hitting your deductible. But if your condition is chronic and your chiropractor is really providing ongoing maintenance, those visits will be denied by Medicare and your Medigap plan won’t touch them. I’ve talked to people who racked up thousands of dollars in chiropractic bills they never anticipated because nobody told them this before they started treatment.

The fix is simple but requires a conversation most people skip. Before you start a course of chiropractic treatment, ask your chiropractor directly: “Will you be billing Medicare for these visits? Do you expect Medicare to approve them, or are they likely to be considered maintenance care?” A good chiropractor’s office will tell you upfront. If they hand you an ABN on your first visit, that’s your signal to ask hard questions before the treatment starts, not after you’ve already had six sessions.

Another mistake worth flagging: some people think a Medicare Advantage plan will handle chiropractic better than Medigap. Sometimes that’s true. Some Medicare Advantage plans include extra chiropractic benefits beyond what Original Medicare covers. But if you’re on Medigap, you’re on Original Medicare, and Original Medicare’s limits apply to you without exception.

When Chiropractic Coverage Actually Works Well With Medigap

There are real situations where Medigap handles chiropractic costs well, and I don’t want to leave you thinking it’s all bad news.

If you have an acute back injury, a new disc problem, or you’re recovering from something that caused genuine functional limitation, Medicare will typically cover chiropractic adjustments as active treatment. In those cases, having a Plan G or Plan N can genuinely protect you from meaningful out-of-pocket costs. Medicare approves the claim, pays 80%, and your Medigap plan covers the 20% coinsurance you’d otherwise owe.

For someone who only needs occasional chiropractic care for acute issues, say a 70-year-old who throws out their back every year or two, the combination of Original Medicare plus a Medigap plan works fine. The care is likely to be covered, and the Medigap plan does exactly what it’s supposed to do.

The people who run into trouble are those with chronic conditions who need regular ongoing adjustments. If that’s you, be honest with yourself about it before you assume your Medigap plan is your safety net for chiropractic.

Bottom Line

Your Medigap plan covers chiropractic care only when Medicare Part B approves it first, and Medicare has strict limits on what it approves. For most people who use chiropractic regularly, a significant portion of their visits won’t be covered by either Medicare or Medigap. Before you start treatment, have a direct conversation with your chiropractor about how they plan to bill Medicare. Don’t assume your Plan G or Plan N makes you bulletproof on chiropractic costs, because it doesn’t.

Frequently Asked Questions

Does Medicare pay for all chiropractic adjustments, or just some?

Medicare Part B pays for spinal manipulation to correct a documented subluxation, but only when the treatment is active and designed to improve function. Once you’ve reached your maximum improvement and visits become maintenance, Medicare stops covering them entirely. There’s no partial coverage for maintenance visits.

If my Medigap plan covers my Part B coinsurance, does that mean chiropractic is fully covered?

Only for visits that Medicare approves. If Medicare denies a chiropractic visit because it’s considered maintenance care or medically unnecessary, there’s no coinsurance for your Medigap plan to pay. You’d owe the full cost of that visit out of pocket.

What is an Advance Beneficiary Notice, and why does it matter for chiropractic?

An ABN is a form your provider gives you when they believe Medicare is likely to deny a service. If you sign it and agree to receive care anyway, you’re agreeing to pay out of pocket if Medicare denies it. For chiropractic, an ABN often means the visit is being coded as maintenance care. Don’t just sign it and move on without understanding what it means for your costs.

Are there Medicare plans that cover chiropractic better than Medigap?

Some Medicare Advantage plans offer additional chiropractic benefits beyond what Original Medicare covers, including a set number of maintenance visits per year. If ongoing chiropractic care is something you rely on, it’s worth comparing Medicare Advantage options in your area against Medigap before you enroll. That said, Advantage plans come with their own tradeoffs, so it’s not a simple switch to recommend across the board.

Plan G Is the Best Medigap Plan for Most 65-Year-Olds

If you’re turning 65 and you want the cleanest, most predictable Medicare coverage you can buy, Plan G is your answer. I’ve watched hundreds of people tie themselves in knots comparing every Medigap option on the market, and the vast majority of them end up in the same place: Plan G covers almost everything, leaves you with exactly one known out-of-pocket cost per year, and lets you see any doctor who accepts Medicare. That’s it. Done.

Now, Plan G isn’t perfect for everyone. If you’re genuinely healthy, rarely see a doctor, and have a solid emergency fund, there’s a legitimate argument for High-Deductible Plan G. And if money is very tight each month, Plan N might make sense. I’ll walk you through all of that. But if someone put a gun to my head and said “just tell me what to pick,” I’d say Plan G, standard version, without hesitation.

Here’s what Plan G actually covers: your Part A hospital coinsurance, your Part B coinsurance (that 20% Medicare leaves you on the hook for), your Part A deductible, skilled nursing facility coinsurance, foreign travel emergency coverage, and your Part B excess charges. The only thing it does not cover is the 2026 Part B deductible, which is $257. That’s the one bill you’ll pay out of pocket all year if nothing catastrophic happens. Every other Medicare-approved cost is handled.

That predictability is worth real money to people. Not just financially, but psychologically. You’re not going to open a bill in February and panic.

How the Main Plans Compare at Age 65

Let me give you a side-by-side look at the plans most 65-year-olds are actually choosing between. I’m leaving out the older plans like Plan C and Plan F, which aren’t available to people who became eligible for Medicare on or after January 1, 2020. If you turned 65 in 2020 or later, those aren’t options for you anyway.

Plan	Monthly Premium (Age 65, Est.)	Part B Deductible Covered?	Part A Deductible Covered?	Part B Coinsurance Covered?	Excess Charges Covered?	Best For
Plan G	$110-$185/month	No (you pay $257 in 2026)	Yes	Yes	Yes	Most people
High-Deductible Plan G	$35-$75/month	No	Yes (after deductible)	Yes (after deductible)	Yes (after deductible)	Healthy, financially prepared
Plan N	$80-$140/month	No	Yes	Yes, with copays	No	Infrequent doctor visits
Plan K	$50-$90/month	No	50%	50%	No	Healthy, want low premium

Premium ranges above are estimates for a 65-year-old non-smoker in 2026. Your actual premium will vary depending on your state, the insurer, and whether they use attained-age, issue-age, or community rating. That rating method matters a lot for what you’ll pay at 75 or 80, so it’s worth asking about it when you shop.

Why Age 65 Is the Best Time to Buy Medigap (and Why You Shouldn’t Wait)

Your 65th birthday doesn’t just trigger Medicare eligibility. It starts a six-month window called the Medigap Open Enrollment Period. During that window, insurers cannot deny you coverage or charge you more because of your health. Pre-existing conditions don’t matter. Your medical history doesn’t matter. Every carrier has to sell you any plan they offer at the standard rate.

Once that window closes, most states allow insurers to use medical underwriting. That means they can reject you outright or charge significantly higher premiums based on your health history. I’ve talked to people in their early 70s who developed a chronic condition in their late 60s and then tried to switch Medigap plans. Some of them were flat-out denied. Others got quoted premiums that were double what they’d have paid at 65.

This is why the advice “just see how things go first” is dangerous. There’s no guaranteed way to get back in later. A few states, including Connecticut, Massachusetts, New York, and Maine, have their own guaranteed issue protections that go beyond federal rules, so if you live there you have a little more flexibility. But in most of the country, missing your Open Enrollment Period is a mistake you can’t easily undo.

The math is also in your favor at 65. You’re younger and healthier, so your premiums are lower. Plan G for a 65-year-old might run $130 a month in Ohio. That same plan for a 72-year-old in Ohio, even if they’re healthy, can be $190 or more. Locking in at 65 with an issue-age rated plan means your premiums start lower and increase more slowly over time.

The Mistake I See People Make Constantly

Here it is: people pick the cheapest monthly premium without understanding what they’re giving up. I see this over and over. Someone decides to go with Plan N instead of Plan G to save $40 a month, without realizing that Plan N doesn’t cover Part B excess charges.

Here’s why that matters. Part B excess charges happen when a doctor doesn’t accept Medicare assignment. They can legally charge up to 15% more than the Medicare-approved amount. If you’re seeing a specialist for a serious condition, and that specialist doesn’t participate in Medicare, those charges can add up fast. Plan G covers them. Plan N doesn’t.

Now, in many states, excess charges are rare or even prohibited. In California, New York, and a handful of others, doctors aren’t allowed to charge them. But if you live in a state where they’re common, say parts of the Northeast or certain metro areas with lots of private-practice specialists, this gap in Plan N can cost you more than the premium savings.

The other mistake is buying Medigap from the first insurer who calls you. Every insurer offering Plan G has to cover the same exact benefits. The only differences are price and service. So shopping around isn’t optional. A 65-year-old woman in Florida might see Plan G quotes ranging from $115 to $175 a month for the same coverage. That’s $720 a year in savings for doing 30 minutes of comparison shopping. Use your state’s SHIP counselor, or a broker who represents multiple carriers, to do this right.

Who Should Consider High-Deductible Plan G Instead

I want to be honest here because High-Deductible Plan G is genuinely a good choice for the right person. It just isn’t right for most people, and I’ve seen it sold to people who really shouldn’t have it.

The 2026 deductible for High-Deductible Plan G is $2,870. Until you hit that number in covered expenses each year, you’re paying out of pocket. After that, the plan kicks in and covers everything standard Plan G covers. Your monthly premium might be $45 to $60 a month instead of $130 to $165.

The break-even math is straightforward. If you’re paying $100 less per month, that’s $1,200 a year in savings. But if you end up with a hospital stay or significant medical expenses, you might owe $2,870 before coverage kicks in. You need to have that money sitting somewhere accessible. Not in the market. Not tied up. Available.

High-Deductible Plan G makes sense if you’re in genuinely good health, you see a doctor a handful of times a year, you have at least $3,000 in liquid savings you can treat as your personal health buffer, and you’re comfortable with the possibility of a bad year where you pay that full deductible. If all of those are true, go for it. You’ll likely come out ahead financially over a 10-year period.

If you have a chronic condition, take multiple medications, or the idea of a $2,870 bill makes you anxious, standard Plan G is worth every extra dollar of premium.

Bottom Line

Plan G is the best Medigap plan for most people turning 65. Buy it during your Open Enrollment Period, shop at least three to five carriers, and ask about the rating method so you understand what your premium trajectory looks like over time. If you’re unusually healthy and financially cushioned, High-Deductible Plan G is worth a serious look. Everyone else: standard Plan G, full stop.

Frequently Asked Questions

Is Plan G better than Plan N for a healthy 65-year-old?

Usually yes, and here’s why. The premium difference between Plan G and Plan N is typically $30 to $50 a month. Plan N exposes you to Part B excess charges and $20 copays for office visits. If you live in a state where excess charges are common and you see specialists, that gap can easily exceed what you’d save in premiums. Plan G gives you cleaner coverage with no copay surprises. Plan N is reasonable if you live in a state that bans excess charges and you rarely need medical care.

Can I switch Medigap plans after age 65 if I change my mind?

You can try, but outside of your Open Enrollment Period, most states allow insurers to decline your application based on health history. If you’ve developed any significant health condition since you first enrolled, you may find you can’t qualify for a different plan. A few states (Connecticut, New York, Massachusetts, Maine) have stronger protections. In most states, though, your best protection is choosing the right plan at 65 in the first place.

Do Medigap premiums go up as you age?

Yes, in most cases. How much depends on whether your plan uses attained-age rating (premiums increase as you get older), issue-age rating (premiums are set at the age you bought, with only inflation-based increases), or community rating (everyone pays the same regardless of age). Attained-age plans look cheap at 65 but can get expensive by 75. Issue-age plans cost a bit more upfront but tend to stay more affordable long-term. Ask your insurer directly which method they use before you buy.

What does Plan G not cover?

Plan G doesn’t cover the 2026 Part B deductible ($257), prescription drugs, dental, vision, or hearing. For prescriptions, you’ll need a separate Part D plan. For dental and vision, you’re looking at standalone coverage or going without. Medigap is designed to cover what Original Medicare covers but doesn’t fully pay. Anything outside Medicare’s scope, Plan G won’t touch either.

The Plans With No Out-of-Pocket Maximum Are the Ones Most People Buy

Here’s something that surprises a lot of people when they first start looking at Medigap: the most popular Medicare supplement plans — Plan G and Plan N — don’t technically have an out-of-pocket maximum at all. Not in the traditional sense. What they have is something arguably better: they cap your exposure so tightly that in most years, your costs are predictable and low. But they’re not zero, and they’re not formally capped with a single number the way employer insurance or Medicare Advantage plans are.

Understanding how each Medigap plan handles your potential out-of-pocket costs is one of the most useful things you can do before picking one. So let me walk you through the real picture, ranked from most protective to least, with actual 2026 numbers and honest opinions about who each plan makes sense for.

How Medigap Plans Actually Limit What You Pay

Original Medicare by itself has no out-of-pocket maximum. None. If you’re hospitalized repeatedly, your Part A deductible resets every 60 days (the 2026 Part A deductible is $1,676 per benefit period). Part B covers 80% of approved outpatient costs, leaving you with 20% of whatever the bill is — with no ceiling. That’s the exposure Medigap exists to address.

Medigap plans limit your costs in one of two ways. Most plans do it by paying specific cost-sharing buckets — deductibles, coinsurance, copays — so you never face those bills in the first place. A smaller set of plans uses a defined out-of-pocket maximum, after which they cover everything. Knowing which approach each plan takes changes how you think about the value you’re getting.

Plan	Part A Deductible Covered?	Part B Deductible Covered?	Part B Coinsurance Covered?	Formal OOP Maximum	Estimated Annual Exposure (Typical Use)
Plan G	Yes	No	Yes (100%)	None (but exposure is just the Part B deductible)	$257 (2026 Part B deductible)
Plan F	Yes	Yes	Yes (100%)	None needed — pays everything	$0
Plan N	Yes	No	Yes (with copays)	None	$257 + up to $20/visit copays + possible excess charges
High-Deductible Plan G	After deductible	After deductible	After deductible	$2,870 (2026)	Up to $2,870
Plan K	50%	No	50%	$7,220 (2026)	Up to $7,220
Plan L	75%	No	75%	$3,610 (2026)	Up to $3,610

A quick note on Plan F: it’s only available to people who turned 65 before January 1, 2020. If you’re newly eligible for Medicare in 2026, it’s off the table. I won’t spend much time on it here for that reason, but if you do qualify, it’s worth a look.

The Plans With Formal Out-of-Pocket Maximums (And Why I’m Not Wild About Them)

Plans K, L, and High-Deductible Plan G are the three Medigap plans that use a defined out-of-pocket maximum. Once you hit that number in a calendar year, the plan pays 100% for the rest of the year. That sounds appealing on paper. In practice, I think these plans are frequently misunderstood and sometimes sold to people who’d be better served elsewhere.

Plan K has a 2026 out-of-pocket maximum of $7,220. Before you hit that ceiling, it only covers 50% of most cost-sharing. That means you’re absorbing half of your Part A hospital coinsurance, half of skilled nursing facility costs, half of hospice coinsurance. For someone who’s in and out of the hospital regularly, that 50% share can pile up fast before you hit the cap.

Plan L is better. Its 2026 maximum is $3,610, and it covers 75% of cost-sharing before the cap kicks in. For a 68-year-old in decent health who wants some protection without paying full Plan G premiums, Plan L can make sense. But it’s still a plan where you’re taking on meaningful exposure in a bad year.

High-Deductible Plan G is the one I actually think deserves more attention. The 2026 deductible is $2,870 — you pay all costs up to that amount, and after that, it works exactly like standard Plan G. The monthly premiums are dramatically lower, often $40-$70/month compared to $120-$180 for standard Plan G depending on your state and age. If you’re 65, healthy, and can absorb up to $2,870 in a rough year, this plan often wins mathematically over a 5-10 year horizon.

The Common Mistake: Confusing “Low Premium” With “Low Risk”

I’ve seen a lot of people make this mistake, and it’s an expensive one. They look at Plan K’s low monthly premium, see “out-of-pocket maximum” on the marketing materials, and assume it’s a budget-friendly safety net. It’s not, at least not in the way they think.

Here’s the thing. A $7,220 out-of-pocket maximum means your downside in a catastrophic year is $7,220 plus your premiums. For someone on a fixed income, that’s a significant financial hit. If you’re paying $60/month for Plan K instead of $150/month for Plan G, you’re saving $1,080 a year in premiums. But it only takes one bad hospitalization with complications to wipe out years of premium savings and then some.

The better framing for any Medigap plan isn’t just the out-of-pocket maximum in isolation. It’s the total worst-case annual cost: your premiums plus your maximum possible cost-sharing. Here’s what that looks like for a 65-year-old in a mid-cost state like Ohio in 2026:

Plan	Est. Monthly Premium (Age 65, Ohio)	Annual Premium	Max Annual OOP	Worst-Case Annual Total
Plan G	$130	$1,560	$257	$1,817
High-Deductible Plan G	$55	$660	$2,870	$3,530
Plan N	$105	$1,260	$257 + copays + excess	~$1,800-$2,200
Plan L	$75	$900	$3,610	$4,510
Plan K	$55	$660	$7,220	$7,880

When you look at it that way, Plan K stops looking like a deal. Plan G’s worst-case total in 2026 is under $1,900. Plan K’s worst case is nearly $8,000. The premium savings don’t come close to justifying that gap for most people.

Who Should Actually Consider Each Plan

I’d give different advice depending on your situation, so let me be specific.

Plan G is the right call for most people turning 65 in 2026. You pay the $257 Part B deductible once a year, and after that you owe nothing for Medicare-approved services. Your monthly costs are predictable. You can see any doctor who accepts Medicare, anywhere in the country. It’s not the cheapest plan, but the total cost picture is usually better than people expect.

High-Deductible Plan G makes a lot of sense if you’re 65, healthy, and have enough in savings to handle a $2,870 hit in a rough year. The math usually favors this plan over standard Plan G if you stay healthy for several years, and the protection is identical once you clear the deductible. A lot of financial-minded retirees I talk to choose this and keep the premium savings in a small reserve fund.

Plan N is worth considering if you want lower premiums than standard Plan G and you’re willing to pay up to $20 for office visits and up to $50 for ER visits. The catch is excess charges — some doctors charge more than Medicare’s approved amount, and Plan N doesn’t cover that gap. If you live somewhere with a lot of Medicare assignment (most urban areas are fine), Plan N is a solid choice. If you’re in a rural area with limited providers, check the excess charge situation first.

Plan L could work for someone who’s genuinely healthy, comfortable self-insuring up to $3,610, and focused on keeping premiums low. I’d rather see most people in Plan G, but I understand the appeal for people in their early 60s on Medicare due to disability who are managing a tight budget.

Plan K is hard for me to recommend to most people. The premium savings relative to the risk exposure rarely pencil out, and the $7,220 ceiling is genuinely scary if you’re on Social Security income.

Bottom Line

For most people turning 65 in 2026, Plan G is the right Medicare supplement plan. It keeps your annual exposure at just the $257 Part B deductible, offers complete predictability, and the worst-case total cost beats every other plan except Plan F (which you probably can’t get). If you’re healthy and cost-conscious, High-Deductible Plan G is the one plan worth genuinely comparing to standard Plan G. The others have their place, but Plan K especially should make you nervous when you run the actual numbers.

Frequently Asked Questions

Does Plan G have an out-of-pocket maximum?

Not in the formal sense, but your real-world exposure is capped at the 2026 Part B deductible of $257 per year. After you pay that once, Plan G covers 100% of Medicare-approved costs for the rest of the year. That’s functionally as good as a $257 out-of-pocket maximum for most people.

Which Medigap plan has the lowest out-of-pocket maximum?

Among plans with a formal defined maximum, High-Deductible Plan G has the lowest at $2,870 in 2026. But standard Plan G limits your real exposure to $257 (the Part B deductible) with no deductible to meet first, which makes it more protective for most people despite having no stated maximum.

Is Plan K worth it if I’m healthy?

Rarely. The low premium looks attractive, but the $7,220 out-of-pocket maximum means one serious illness could cost you far more than you saved on premiums. Unless you’re in genuinely excellent health with significant liquid savings and a clear preference for self-insuring, Plan G or High-Deductible Plan G almost always beats Plan K on total expected cost.

Can my out-of-pocket costs really be zero with a Medigap plan?

With Plan F, yes — but only if you were eligible for Medicare before January 1, 2020. With Plan G, your only guaranteed cost is the $257 Part B deductible in 2026. After that, your costs for Medicare-approved services are zero for the rest of the calendar year. That’s about as close to zero ongoing exposure as you can get in the American healthcare system.

Yes, Medigap Covers Physical Therapy — But Medicare Leads the Way

Medicare supplement plans do cover physical therapy, but they’re not doing the heavy lifting on their own. They’re picking up what Original Medicare leaves behind. That distinction matters more than most people realize when they’re shopping for a plan.

Here’s how it actually works: Medicare Part B covers outpatient physical therapy, occupational therapy, and speech-language pathology as long as your doctor certifies the treatment is medically necessary. Part B pays 80% of the Medicare-approved amount after you’ve met the 2026 Part B deductible of $257. Your Medigap plan then pays the remaining 20% coinsurance — which is where your real protection comes from.

For inpatient rehab (like a skilled nursing facility after a hospital stay), you’re dealing with Part A rules instead. The 2026 Part A deductible is $1,676 per benefit period. A good Medigap plan covers that deductible and the daily coinsurance that kicks in for longer stays.

I’ve spent years watching people assume their Medigap plan covers therapy independently, like a standalone benefit. It doesn’t work that way. If Medicare won’t pay for a therapy session, your Medigap plan won’t either. They move together. Understanding that relationship upfront will save you from some genuinely unpleasant surprises.

What Part B Covers for Outpatient Therapy (And the Limits That Catch People Off Guard)

Congress eliminated the old therapy caps back in 2018, which was a huge deal for people with chronic conditions or serious injuries. Before that, there was a hard dollar limit on how much Medicare would pay for outpatient therapy in a year. Now there’s no cap, but there is a threshold called the KX modifier amount that changes annually.

In 2026, once your outpatient therapy costs exceed $2,330 for physical therapy and speech-language pathology combined (or $2,330 separately for occupational therapy), your provider has to add a KX modifier to your claim. This modifier certifies that continued therapy is medically necessary. Medicare can also conduct a medical review to verify that. It’s not automatic denial — it’s a checkpoint. But if your provider doesn’t document things properly, claims can get kicked back.

For most people going through routine post-surgery rehab or recovering from a fall, the $2,330 threshold is more than enough. But if you’re managing something like a stroke, a serious spinal injury, or a progressive neurological condition, you could blow past that number fast. I’ve talked to people who needed six months of intensive speech therapy after a stroke and racked up far more than that. Medicare kept paying, but only because the therapy was well-documented as medically necessary at every step.

Your Medigap plan follows along for the ride. If Medicare approves the claim, your plan pays its share. That 20% coinsurance adds up quickly when you’re doing three sessions a week over several months.

How Different Medigap Plans Handle Therapy Costs

Not all Medigap plans are created equal here, and the differences are worth knowing before you lock yourself into a plan.

Medigap Plan	Part B Coinsurance (Outpatient Therapy)	Part A Deductible	Skilled Nursing Coinsurance (Days 21-100)	Part B Deductible
Plan G	100% covered	100% covered	100% covered	You pay $257 (2026)
Plan N	Covered (copays may apply)	100% covered	100% covered	You pay $257 (2026)
Plan K	50% covered	50% covered	50% covered	You pay $257 (2026)
Plan L	75% covered	75% covered	75% covered	You pay $257 (2026)
Plan A	100% covered	Not covered	Not covered	You pay $257 (2026)

Plan G is the one I recommend to most people who are asking me about therapy and rehab coverage. You pay the Part B deductible once a year, and after that, you’re essentially fully covered for anything Medicare approves. Plan G premiums typically run between $100 and $200 a month at age 65 depending on where you live and which insurer you go with. That’s a predictable cost you can budget around.

Plan N is a reasonable middle ground if you’re generally healthy, but watch out for the potential copays of up to $20 per outpatient visit and up to $50 for emergency room visits. If you’re doing physical therapy three times a week, those $20 copays can eat into your savings fast. Do the math for your specific situation before assuming Plan N is the cheaper option.

Plans K and L were designed to lower premiums by sharing more costs with you. For someone who rarely uses medical care, that might be fine. For someone who needs ongoing rehab, they’re often the wrong choice. I’ve seen people on Plan K get blindsided by their out-of-pocket costs during extended therapy. The out-of-pocket maximums for these plans exist, but they’re higher than most people expect.

The Big Misconception: Skilled Nursing Facility Coverage After a Hospital Stay

This is where I see people get genuinely hurt financially. Not because the rules are hidden, but because they’re confusing and the hospital doesn’t always explain them clearly.

Here’s the mistake: people assume that any stay in a skilled nursing facility (SNF) for rehab is automatically covered by Medicare. It’s not. You have to meet a very specific requirement first. You must have had a qualifying inpatient hospital stay of at least three days (not counting the day you’re discharged). That’s three full days as a formal inpatient admission, not under “observation status.”

Observation status is the landmine here. If your hospital classifies you as under observation, even if you’re sleeping in a hospital bed for four nights, you don’t have a qualifying stay. You cannot then get Medicare to pay for skilled nursing rehab. I’ve seen this happen to people after hip replacements, after falls, after cardiac events. They thought they were covered. They weren’t, and the bills were devastating.

If Medicare does cover your SNF stay, here’s what the 2026 numbers look like: Medicare pays 100% for days 1-20. For days 21-100, there’s a daily coinsurance of $209.50. After day 100, Medicare pays nothing. Plan G and Plan N both cover that daily coinsurance fully for days 21-100, which is where Medigap really earns its premium for people who need extended rehab.

Ask about your admission status at the hospital. Actually ask. Don’t assume inpatient status. It’s one of the few things I tell everyone regardless of their situation.

Home Health Therapy: A Different Animal

If you’re homebound and a doctor orders physical therapy at your home, Medicare Part A or Part B can cover home health services, including physical and occupational therapy. Interestingly, this is one area where Medigap has limited direct impact, because Medicare typically pays 100% for covered home health visits with no coinsurance required from you.

The catch is the definition of “homebound.” Medicare defines this strictly. You have to have a condition that makes leaving home require considerable effort. If you’re walking around the neighborhood or driving to appointments regularly, you likely don’t qualify for home health benefits. Medicare audits home health claims aggressively.

There is a 20% coinsurance for durable medical equipment sometimes associated with home therapy, and your Medigap plan does cover that. But for the therapy visits themselves, you’re often not paying out of pocket anyway, which is genuinely good news if you qualify.

Bottom Line

For most people who want solid protection against the costs of physical therapy and rehab, Plan G is the right call. It eliminates almost all out-of-pocket exposure once you’ve paid the annual Part B deductible, and it covers both the outpatient therapy coinsurance and the skilled nursing facility daily charges that can otherwise run into the tens of thousands. If you’re choosing between plans and you have any reason to expect significant therapy needs, don’t let a slightly lower Plan N premium talk you into absorbing per-visit copays that add up faster than you’d think.

Frequently Asked Questions

Does Medicare cover physical therapy with no limit on sessions?

There’s no annual session limit anymore. Medicare covers medically necessary outpatient therapy without a cap on the number of visits. Once costs exceed $2,330 (2026 threshold) for PT and speech therapy combined, providers have to document medical necessity more explicitly, but coverage doesn’t stop.

Will my Medigap plan cover therapy if Medicare denies the claim?

No. If Medicare denies a therapy claim, your Medigap plan won’t cover it either. Medigap only pays for costs that Medicare has already approved. That’s why the medical necessity documentation from your provider matters so much. If a claim is denied, you can appeal, and it’s often worth doing.

What happens if I need rehab in a skilled nursing facility for more than 100 days?

Medicare stops paying entirely after day 100 in a benefit period. No Medigap plan covers SNF costs beyond day 100. For extended care, you’d be looking at Medicaid (if you qualify) or paying out of pocket. This is one of the legitimate gaps in standard Medigap coverage that people should plan around separately.

Does Medigap cover gym-based or wellness physical therapy?

Generally not. If a physical therapist is providing medically necessary treatment that Medicare approves, your Medigap plan covers its share. But general fitness programs, maintenance exercise classes, or gym memberships aren’t covered by Medicare or Medigap, even if a doctor recommended exercise for your health. The line is medical necessity, and maintenance exercise usually doesn’t meet that bar under Medicare’s definitions.

What Plan M Actually Covers (And Where It Cuts Corners)

Plan M is one of the lesser-known standardized Medigap plans, and that’s partly because it occupies a strange middle ground that doesn’t work for everyone. It covers most of what Plan G covers, but with two significant gaps: it only pays half of the Medicare Part A hospital deductible, and it doesn’t cover the Part B deductible at all.

Here’s the full picture of what Plan M does and doesn’t cover:

Benefit	Plan M	Plan G (for comparison)
Medicare Part A coinsurance and hospital costs	Yes	Yes
Medicare Part B coinsurance or copayment	Yes	Yes
Blood (first 3 pints)	Yes	Yes
Part A hospice care coinsurance or copayment	Yes	Yes
Skilled nursing facility coinsurance	Yes	Yes
Part A deductible (2026: $1,676 per benefit period)	50% only	100%
Part B deductible (2026: $257)	No	No
Part B excess charges	No	Yes
Foreign travel emergency (up to plan limits)	80%	80%

That Part A deductible is the big one to pay attention to. In 2026, it’s $1,676 per benefit period, not per year. If you get hospitalized twice in a year under separate benefit periods, you’d owe $838 each time with Plan M, while a Plan G holder pays nothing. That adds up faster than most people expect.

The Part B deductible not being covered isn’t a dealbreaker for most people. At $257 in 2026, you pay it once per year before Medicare starts covering your outpatient care. That’s annoying but manageable. The Part A cost-sharing is the real exposure here.

What Plan M Costs and How the Math Works

Plan M premiums run meaningfully lower than Plan G premiums, typically 15 to 25 percent less depending on your insurer, state, and age. For a 65-year-old woman in a mid-size market, you might see Plan G at around $130 to $160 per month and Plan M in the $100 to $130 range. The gap varies a lot by location.

Let’s run the numbers honestly. Say you’re paying $130/month for Plan G versus $108/month for Plan M. That’s a $264 annual savings on premiums. In exchange, you’re taking on up to $838 in potential out-of-pocket costs from your half of the Part A deductible, plus the $257 Part B deductible.

If you don’t get hospitalized, Plan M wins. If you have one hospitalization, you’re roughly breaking even or slightly behind. Two hospitalizations in a year and Plan M has cost you more than Plan G would have.

The question isn’t just math, though. It’s also about your risk tolerance. Some people sleep better knowing their hospital bills are covered completely. Others genuinely prefer lower monthly premiums and are willing to absorb the occasional out-of-pocket cost. Neither preference is wrong, but you need to go in with clear eyes about what you’re trading.

One more thing: Plan M premiums are set by each insurer individually, even though the benefits are standardized by federal law. Two different companies can charge very different prices for identical Plan M coverage. Always compare multiple quotes in your area before you buy.

The Biggest Misconception About Plan M

I’ve seen a lot of people assume Plan M works like a high-deductible plan where you’re gambling that you’ll stay healthy. That’s not quite right, and the confusion leads people to either dismiss Plan M unfairly or choose it for the wrong reasons.

Plan M is not a high-deductible plan. There’s a separate product called Plan G High Deductible that has a $2,870 deductible in 2026 before your coverage kicks in. Plan M has no annual deductible of its own. You only pay cost-sharing on the specific items that Plan M leaves partially or fully uncovered, which is primarily that 50% of the Part A hospital deductible.

The other misconception I run into constantly is that people think the Part B deductible not being covered is a bigger deal than it is. I understand why: anything labeled a “gap” sounds alarming when you’re trying to fill gaps. But $257 once a year is genuinely not a significant financial exposure. You’d pay that from your wallet without it stressing your budget. The Part A deductible is a different story because it can hit multiple times in a year.

Also, Plan M does cover Part B excess charges on some policies depending on the insurer’s offering, but in the standardized federal definition, Plan M does not include excess charge protection. Don’t assume you’re covered for that. Always read the policy summary, not just the plan name.

Who Plan M Is Actually Right For

Here’s where I’ll be direct with you, because too many articles dodge this question.

Plan M makes the most sense for people who are genuinely healthy, have a solid emergency fund to cover a surprise hospital bill, and are primarily motivated by keeping their monthly premium down without dropping to a less protective plan entirely. A 67-year-old in Ohio who’s never been hospitalized, sees her doctor three or four times a year for routine visits, and has $10,000 sitting in savings she could tap if needed? Plan M could be a smart choice for her.

It’s also worth considering if you live in a state where Plan G premiums are especially high. In some markets, the premium difference between Plan G and Plan M is large enough that the savings are hard to ignore even with the added risk.

Plan M is probably not right for you if:

• You have a chronic condition that leads to frequent hospitalizations
• You’re on a fixed income where a surprise $800 bill would genuinely cause hardship
• You hate the idea of having any cost-sharing exposure after paying monthly premiums
• The premium difference in your area between Plan M and Plan G is less than $15 to $20 per month

That last point matters more than people realize. If the savings are only $10 or $12 a month, you’re not saving enough to justify taking on any additional risk. The math just doesn’t work in your favor.

How Plan M Compares to Plan N (The Other “Middle Ground” Option)

If you’re looking at Plan M, you should almost certainly also look at Plan N before you decide. They’re both positioned as lower-premium alternatives to Plan G, and they attract a similar type of buyer.

Feature	Plan M	Plan N
Part A deductible coverage	50% (you pay ~$838 in 2026)	100% covered
Part B deductible	Not covered	Not covered
Part B excess charges	Not covered	Not covered
Office visit copays	None	Up to $20 copay
Emergency room copay	None	Up to $50 (waived if admitted)
Typical premium vs. Plan G	15-25% lower	15-20% lower

In my experience, Plan N tends to be the better deal for most people who want lower premiums. Here’s why: Plan N covers 100% of the Part A deductible, which is your biggest financial exposure. Yes, you’ll pay up to $20 for some office visits and up to $50 for emergency room trips, but if you’re only seeing your doctor four or five times a year, those copays add up to maybe $80 to $100 annually. That’s usually less exposure than carrying half the Part A deductible.

That said, if you’re a frequent outpatient visitor who rarely ends up in the hospital, Plan M’s structure might actually work better. This is one situation where your personal health history genuinely matters. Think about how you actually use healthcare, not how you hope you’ll use it.

Bottom Line

Plan M is a legitimate option, but it’s not the first plan I’d recommend to most people. For healthy, financially stable Medicare beneficiaries who want meaningful savings on their monthly premium and can absorb occasional cost-sharing, it’s worth a serious look. For most people, though, Plan N offers a cleaner trade-off because it eliminates your biggest out-of-pocket risk (the hospital deductible) while still delivering lower premiums than Plan G. Compare both side by side with real quotes from your state before you decide anything.

Frequently Asked Questions

Is Plan M available in all states?

Plan M is a federally standardized plan, which means insurers are allowed to offer it, but they’re not required to. In practice, Plan M isn’t available from many carriers in most states, which is part of why it flies under the radar. You may find only one or two insurers in your area offering it. Always use a quote tool that checks multiple carriers, because availability varies significantly by ZIP code.

Can I switch from Plan M to Plan G later if I want more coverage?

Possibly, but it’s not guaranteed. After your initial Medigap open enrollment period ends, insurers in most states can use medical underwriting to decide whether to cover you. If you’ve developed a health condition since you first enrolled, you might be denied or charged more. Minnesota, Connecticut, and Massachusetts have different rules, but in most states, switching plans later carries real risk. Don’t count on being able to upgrade later just because you can afford to then.

Does Plan M cover emergency care when I travel outside the U.S.?

Yes. Plan M includes foreign travel emergency coverage at 80% after a $250 deductible, up to a lifetime limit of $50,000. That matches what Plan G offers for foreign travel. It’s not unlimited, and it only applies to emergencies, not routine care abroad. If you’re a frequent international traveler, look closely at those limits and consider whether supplemental travel insurance might fill any remaining gaps.

What happens if I see a doctor who doesn’t accept Medicare assignment with Plan M?

If a provider charges more than Medicare’s approved amount (called excess charges), Plan M does not cover those extra costs. You’d owe the difference out of pocket, which can be up to 15% above Medicare’s approved rate. This is the same situation as Plan N buyers. If you see specialists who don’t accept Medicare assignment, this is a real exposure. The fix is simple: ask whether your doctors accept Medicare assignment before you enroll in any plan that doesn’t cover excess charges.

The Short Answer: Yes, But Don’t Count On It Being Easy

You can try to switch Medicare supplement plans any time of year. The problem is that most insurers don’t have to accept you, and most of the time, they won’t if you have health issues. That’s the part nobody tells you upfront, and it trips up a lot of people who assume Medicare’s open enrollment rules work the same way for Medigap as they do for other types of insurance.

Here’s the thing. Medigap is private insurance sold by private companies. Outside of a few protected windows, those companies can run you through medical underwriting, ask about your health history, and flat-out deny your application or charge you significantly more. In most states, this applies whether you’re switching plans in January, July, or any other month.

So yes, mid-year switches are possible. But whether you’ll actually get approved, and at what price, depends almost entirely on your health status and which state you live in.

How Medical Underwriting Works Against You When You Switch

When you first signed up for Medicare Part B, you had a six-month window called the Open Enrollment Period. During that window, insurers had to sell you any Medigap plan at standard rates, no questions about your health. That window is gone now. It doesn’t come back just because you want a different plan.

Outside of that initial window, insurers in most states can ask you questions like: Have you been hospitalized in the past two years? Do you have diabetes, heart disease, COPD, or cancer? Are you currently taking blood thinners? If the answers raise flags, they can decline your application entirely.

I’ve seen people get rejected for conditions they considered minor. A history of atrial fibrillation, a knee replacement from three years ago, even some mental health diagnoses have caused denials. The underwriting standards vary by insurer, but they’re real, and they bite people who weren’t expecting them.

This is why the timing of a switch matters so much. If you’re in good health right now and your current plan’s premiums are climbing, switching mid-year might make perfect financial sense. If you’ve had health events recently, you may be stuck where you are until a protected window opens up for you.

Situations Where You Have the Right to Switch Without Underwriting

There are specific situations where you’re legally protected and insurers must accept you, no health questions. These are called Guaranteed Issue rights, and they’re worth knowing because they’re the only reliable path to switching if your health isn’t perfect.

• Your insurer leaves your area or goes bankrupt. If your current Medigap insurer stops doing business in your state, you have 63 days to switch to another plan without underwriting.
• You have employer coverage that’s ending. If you delayed Medigap and had employer group health coverage that’s now ending, you may have a guaranteed issue window.
• You enrolled in a Medicare Advantage plan and want to switch back. If you moved from Original Medicare plus Medigap to a Medicare Advantage plan, and within the first year you decide Advantage isn’t for you, you can switch back to a Medigap plan with guaranteed issue rights.
• Your Medicare Advantage plan leaves your area or ends. Same principle: you get a protected window to pick up Medigap coverage without health screening.

Outside of these situations, you’re in underwriting territory. Which means your health, not the calendar, controls whether a mid-year switch is realistic for you.

The Misconception That Kills People’s Plans: Assuming Lower Premiums Means a Better Deal

This is the mistake I see most often, and it’s an expensive one. Someone calls around, finds a Plan G with a premium that’s $40 a month cheaper than what they’re currently paying, and starts celebrating. They apply, get approved (or assume they will), and cancel their existing coverage. Then something goes wrong in the process, and suddenly they’re either uninsured for a period or stuck paying both premiums.

A few things people get wrong here:

1. They cancel their current plan before the new one is confirmed. Never do this. Keep your existing Medigap coverage active until you have written confirmation that your new plan is in force. Insurers can rescind applications. Processing delays happen.
2. They don’t account for the timing of premium billing. If you switch mid-month, you may owe partial premiums to both insurers. That’s fine, but factor it into your math.
3. They compare premiums without comparing rate increase histories. A plan that’s $30 cheaper today might have raised rates 12% last year, while your current plan raised rates 4%. Chasing the current lowest premium without looking at the trajectory is short-sighted.

Here’s a comparison of what matters when evaluating a mid-year switch:

Factor	What Most People Focus On	What You Should Actually Compare
Premium	Current monthly cost	3-5 year rate increase history
Benefits	Plan letter (G, N, etc.)	Identical across all insurers for same plan letter
Pricing method	Often ignored	Community-rated vs. issue-age vs. attained-age
Insurer stability	Often ignored	A.M. Best rating, years in Medicare market
Underwriting requirements	Often ignored	Whether you’ll actually get approved

The benefits for a given plan letter are standardized by federal law. A Plan G from Aetna pays exactly the same claims as a Plan G from Mutual of Omaha. So the only things you’re really comparing are price, price stability, and whether the insurer will accept you. Don’t overcomplicate it.

State Exceptions That Actually Give You More Freedom

A handful of states have passed their own rules that give residents more switching flexibility than federal law requires. If you live in one of these states, your options are genuinely better.

California has a Birthday Rule: during the 60 days following your birthday each year, you can switch to a plan with equal or lesser benefits from any insurer without underwriting. So if you’re a 69-year-old in California with health issues, you have a real annual window to shop.

Oregon has a similar Birthday Rule with the same 60-day window.

Idaho and Nevada also have Birthday Rule provisions, though the specific rules differ slightly, so verify the current details for your situation.

Missouri, Illinois, and a few others have anniversary rules or other consumer protections worth looking into.

Connecticut, Maine, Massachusetts, and New York have guaranteed issue year-round, meaning insurers in those states can’t deny you based on health at any point. If you live in one of these states, mid-year switching is as easy as finding a lower premium and filling out an application. It’s genuinely that simple there.

If you’re not in one of these states and you’re in decent health, the best time to switch is when you find a better deal and can pass underwriting. Don’t wait for an imaginary “right time” that doesn’t exist in most states.

The Real Financial Math on Switching Mid-Year

Let’s make this concrete. Say you’re a 67-year-old in Ohio on Plan G, currently paying $178 a month. You find another Plan G from a highly-rated insurer at $139 a month. That’s a $39 monthly difference, or $468 a year.

If you pass underwriting, switching is almost certainly worth it. The 2026 Plan G benefits are identical either way: you’re covered for everything Medicare Part A and Part B cover, except the Part B deductible (which is $257 in 2026). Same hospital coverage, same Part A deductible ($1,676 per benefit period in 2026), same coinsurance. The check you get when you need care looks exactly the same. The only variable is what you pay monthly.

Now factor in whether the new insurer uses attained-age pricing (rates go up as you age) vs. community-rated (everyone pays the same regardless of age). If the cheaper plan uses attained-age pricing, that $39 gap might disappear in two or three years and reverse after that. This is worth a direct conversation with the insurer or an independent broker before you switch.

That said, for a healthy person in a state without special protections, I’d still recommend switching when the savings are meaningful and the insurer is financially stable. Waiting costs you real money while you deliberate.

Bottom Line

If you’re in good health and you’ve found a lower-priced Plan G or Plan N from a reputable insurer, switch. Don’t wait for a specific time of year, because there’s no special mid-year window that helps you in most states. Apply, get approved in writing, then cancel your old coverage. If your health has changed significantly since you first enrolled, or you’ve had recent hospitalizations or diagnoses, talk to an independent broker who can tell you which underwriters in your state are most likely to approve you before you apply anywhere.

Frequently Asked Questions

Is there a Medigap open enrollment period each year like there is for Medicare Advantage?

No. This is one of the most common points of confusion. The annual October 15 through December 7 enrollment period applies to Medicare Advantage and Part D drug plans, not Medigap. Your one guaranteed Medigap open enrollment window is the six months after you first enroll in Part B. After that, you’re subject to underwriting in most states.

Can I have two Medigap plans at once during a switch?

Technically you can overlap briefly, but you won’t get benefits from both. You can only have one active Medigap policy covering you at a time. It’s fine to keep the old plan active until the new one confirms, but cancel promptly once you have written confirmation of the new coverage to avoid unnecessary double premiums.

What happens to my Medigap coverage if I’m hospitalized while I’m switching plans?

This is exactly why you should never cancel your current plan before the new one is confirmed in writing. If you’re between plans when a hospitalization happens, you could face significant out-of-pocket costs. The 2026 Part A deductible is $1,676 per benefit period, and that’s just the starting exposure. Keep coverage active through the transition.

My premiums went up 15% this year. Should I switch even though I have some health issues?

It depends on the nature of those health issues. Mild, well-controlled conditions sometimes pass underwriting. Serious or recent conditions often don’t. Before you apply anywhere and create a record of a denial, talk to an independent Medigap broker who knows which carriers in your state are more lenient. Some insurers are stricter than others, and applying to the wrong one first can make your situation harder. If you’re in California, Oregon, or one of the guaranteed-issue states, none of this applies: shop freely.

Yes, Medigap Covers Ambulance — But It Works in Layers

Medicare supplement plans do cover ambulance services, but not in the way most people expect. You don’t just hand over your Medigap card and walk away with no bill. It’s a two-step process, and if you don’t understand both steps, you’re going to be confused when you get the explanation of benefits.

Here’s how it actually works. Original Medicare (Part B) covers medically necessary ambulance transport at 80% after you meet your deductible. That leaves you with the remaining 20% coinsurance, which is where your Medicare supplement kicks in. Depending on which plan you have, Medigap pays some or all of that 20%.

For 2026, the Part B deductible is $257. Once you’ve met that for the year, Medicare pays its 80% share on an approved ambulance claim. Your Plan G, Plan N, or whatever plan you carry then steps in behind Medicare to cover what’s left.

That leftover 20% isn’t small. An average ground ambulance transport runs $1,200 to $2,000 before Medicare discounts. After Medicare’s 80%, you could still be looking at $240 to $400 out of pocket on a single ride — and that’s assuming the ambulance company accepts Medicare assignment. If they don’t, costs can be significantly higher.

What “Medically Necessary” Actually Means for Ambulance Coverage

This is where a lot of people get blindsided. Medicare doesn’t cover ambulance transport just because you called 911 or because your doctor said you needed it. Medicare covers ambulance transport when it’s medically necessary AND when other transportation would be contraindicated for your condition.

In plain terms: if you could have safely ridden in a car or wheelchair van, Medicare can deny the ambulance claim entirely. That means your Medigap plan has nothing to pay, because Medigap only pays what Medicare approves first.

Examples that typically qualify as medically necessary:

• You’re unconscious or in active cardiac arrest
• You need to be immobilized due to a fracture or spinal injury
• You require oxygen or IV medications during transport
• Your condition requires monitoring that only trained EMTs can provide

Examples that often don’t qualify:

• Routine transport to dialysis (there are specific rules here — see below)
• Non-emergency transport to a doctor’s office when you could sit in a car
• Convenience-based ambulance use, even if you feel unwell

Dialysis is a special case worth knowing about. Medicare does cover ambulance transport to and from dialysis for patients who are bed-confined, but not just because someone needs dialysis. The patient has to meet the medical necessity standard on top of needing dialysis. I’ve seen people assume dialysis automatically means covered ambulance rides, and that’s not accurate.

How Each Major Medigap Plan Handles Ambulance Costs

Not all Medicare supplement plans work the same way here. The differences come down to how much of that Part B coinsurance (the 20%) and the Part B deductible they cover.

Medigap Plan	Part B Deductible (2026: $257)	Part B Coinsurance (20%)	Your Out-of-Pocket on Ambulance
Plan G	You pay it once per year	Medigap pays 100%	$257 first use of year, then $0
Plan N	You pay it once per year	Medigap pays 100%	$257 first use of year, then $0
Plan F (pre-2020 enrollees only)	Medigap pays it	Medigap pays 100%	$0
Plan K	You pay it once per year	Medigap pays 50%	$257 deductible + 10% of approved charge
Plan L	You pay it once per year	Medigap pays 75%	$257 deductible + 5% of approved charge
High-Deductible Plan G	Applied to your deductible	Applied to your deductible	Up to $2,870 (2026 deductible) before coverage kicks in

If ambulance use is a realistic concern for you — you have a heart condition, you’re recovering from a stroke, you live alone in a rural area where an emergency is more likely to require transport — Plan G or standard Plan N gives you the cleanest coverage once that annual deductible is met.

The Mistake That Costs People Real Money

I’ve seen this happen more times than I can count: someone gets taken by ambulance, the ambulance company is out-of-network, and the person assumes their Medigap plan will cover the gap the same way it does for in-network care. It doesn’t always work that way, and here’s why.

Original Medicare has an “approved amount” for ambulance services. If the ambulance company accepts Medicare assignment, they agree to take that approved amount as payment in full (minus your cost-sharing). But if the company doesn’t accept assignment, they can charge you up to 15% more than Medicare’s approved amount on top of your 20% coinsurance. That extra 15% is called the Part B excess charge.

Here’s the catch: Plan N does not cover Part B excess charges. Plan G does cover them. So if you have Plan N and you’re transported by a non-participating ambulance provider, you could owe that 20% coinsurance plus the 15% excess charge, all at once.

In a rural area, this is particularly relevant. Rural ambulance providers are more likely to be independent companies that haven’t signed Medicare assignment agreements. If you’re 68 years old, living 40 minutes from the nearest hospital, and your area has one ambulance service that doesn’t take assignment, you want Plan G. Not Plan N, not a high-deductible plan. Plan G.

There’s another misconception I want to address head-on: some people think that because their Medicare Advantage plan “covers ambulance,” they don’t need to think carefully about this. Medicare Advantage handles ambulance differently than Original Medicare plus Medigap. With MA plans, you’re subject to whatever copays and network rules that specific plan has. Some MA plans charge $250-$300 per ambulance trip regardless of the situation. If you’re comparing Medigap to Medicare Advantage, ambulance coverage is one of the areas where traditional Medicare plus a solid Medigap plan often wins.

Air Ambulance: The Coverage Gap Nobody Talks About

Ground ambulance is relatively straightforward once you understand the rules. Air ambulance is a different beast, and I’d be doing you a disservice if I didn’t flag this separately.

Medicare Part B does cover medically necessary air ambulance transport under the same 80/20 structure as ground transport. Your Medigap plan covers that 20% the same way. The problem is that air ambulance providers have historically been among the most aggressive non-participating providers in the country.

Before the No Surprises Act (which took effect in 2022), air ambulance companies could bill you astronomically above Medicare rates, and Medigap only covered the Medicare-approved portion. The No Surprises Act improved protections for people with private insurance, but Medicare beneficiaries operate under different rules. You’re protected from the worst abuses, but air ambulance billing disputes do still happen.

If you live somewhere that air transport is realistically possible in an emergency (mountainous areas, rural regions, areas with major trauma centers far away), ask your Medigap insurer specifically how they handle air ambulance claims and whether your plan covers Part B excess charges. Get it in writing.

Bottom Line

For most people, Plan G is the right call when ambulance coverage matters to you. It covers the 20% coinsurance, it covers Part B excess charges from non-participating providers, and after you pay the 2026 deductible of $257 once in January, you’re protected for the rest of the year. If you’re in a rural area, have a cardiac history, or live alone, don’t let a $20-40/month premium difference between Plan G and Plan N push you toward a plan that leaves you exposed to excess charges when it matters most.

Frequently Asked Questions

Does Medicare supplement cover non-emergency ambulance transport?

Only if Original Medicare covers it first. Medigap doesn’t override Medicare’s medical necessity rules. If Medicare denies the ambulance claim because the transport wasn’t medically necessary, your Medigap plan pays nothing. The determination of medical necessity is made by Medicare based on the documentation from the ambulance provider and your medical records.

What if the ambulance takes me out of state?

Medicare Part B covers medically necessary ambulance transport regardless of state lines, as long as it meets the medical necessity criteria. Your Medigap plan follows the same rules. Unlike Medicare Advantage, Medigap plans work anywhere in the country that accepts Medicare, so crossing a state line doesn’t change your coverage.

Will Medigap cover ambulance if I’m taken to an out-of-network hospital?

Yes. This is actually one of the big advantages of Original Medicare plus Medigap over Medicare Advantage. There’s no network restriction for Medigap. If the ambulance takes you to a hospital that accepts Medicare (which is virtually all hospitals), your Medigap plan covers the applicable cost-sharing regardless of which hospital it is.

I have Plan N. Am I really exposed to extra costs for ambulance?

Potentially, yes. Plan N doesn’t cover Part B excess charges. If your ambulance provider doesn’t accept Medicare assignment and bills the 15% excess charge, you’ll owe that out of pocket on top of your 20% coinsurance. In most urban and suburban areas, this is rare because most ambulance companies do accept assignment. But if you’re in a rural area or somewhere with limited provider options, it’s a real risk worth knowing about before you need a ride.
