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.
