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.
