If you need physical therapy and you’re on Medicare, the short answer is this: Medicare Part B generally covers outpatient physical therapy as medically necessary care, and you typically pay 20% of the Medicare-approved amount after your deductible. There’s no hard annual cap on how many visits you can receive, but there is a soft spending threshold that triggers extra paperwork. Original Medicare and Medicare Advantage handle therapy coverage differently, so where you get your coverage matters.
How Much Does Medicare Cover For Physical Therapy?
Medicare Part B covers outpatient physical therapy at 80% of the approved amount. You pay the remaining 20%, plus your annual deductible, which is $240 in 2024.
This applies to therapy you receive from a Medicare-enrolled provider. The therapist must accept assignment, meaning they agree to charge no more than Medicare’s approved rate. Most physical therapists do accept assignment, but it’s worth confirming before your first appointment.
What counts as “medically necessary” is the key phrase here. Medicare covers therapy that treats a specific condition or helps you recover function after injury, surgery, or illness. It does not cover therapy to maintain a general level of fitness or to prevent future problems when no current medical need exists.
Your doctor or treating provider must certify that you need skilled therapy and that your condition is expected to improve, or that you need therapy to maintain function after a decline. The specifics of that certification process have evolved, but the core requirement — documented medical necessity — has not changed.
Does Medicare Limit How Many Physical Therapy Visits You Can Have?
There is no fixed cap on the number of physical therapy visits Medicare will cover. Congress removed the hard annual dollar limits on therapy services years ago. What replaced them is a soft threshold.
When your therapy costs exceed a certain amount in a calendar year — $2,330 in 2024 — your provider must add a modifier code to the claim indicating the services are medically necessary. This triggers a review process. It does not mean coverage stops. It means Medicare wants documentation that the therapy is still justified.
In practice, most people never hit this threshold. Those who do are typically receiving intensive or long-term therapy. If you’re approaching it, your therapist will likely discuss it with you.
The bigger limiting factor is medical necessity, not visit count. If your therapist documents that you’re making progress or that continued therapy is needed to maintain function, Medicare generally continues to pay. If progress stalls and the therapy becomes maintenance care with no skilled need, coverage may end.
Does Medicare Advantage Cover Physical Therapy Differently?
Yes, and the differences can be significant. Medicare Advantage plans are required to cover everything Original Medicare covers, but they can add their own rules.
Many Medicare Advantage plans require prior authorization before you start physical therapy. Some limit the number of visits they’ll approve at a time — often 12 to 20 — and require your therapist to request more. Others may have different copays, which can range from $0 to $50 or more per visit depending on the plan.
The 20% coinsurance that applies to Original Medicare doesn’t necessarily apply to Medicare Advantage. Your cost-sharing depends entirely on your specific plan’s benefit design.
This is where Medicare Advantage can either save you money or cost you more, depending on your plan and how much therapy you need. A plan with a $10 copay per visit is cheaper than 20% coinsurance if the approved amount is $150 per session. A plan with a $40 copay is not.
If you’re on Medicare Advantage and your therapist recommends ongoing treatment, expect the plan to review your case periodically. Approval for 12 visits doesn’t guarantee approval for the next 12.
What About the Part B Deductible and Medigap?
You pay the full cost of physical therapy until you meet your Part B deductible. In 2024, that deductible is $240. After that, Medicare pays 80% and you pay 20% of the approved amount.
If you have a Medigap supplement plan, it may cover your 20% coinsurance and your deductible. Medigap Plan G, for example, covers the Part B coinsurance after you pay the deductible. Plan F, which is no longer available to new enrollees but still exists for some, covers both.
This matters for therapy because the 20% can add up. If your therapist charges $150 per session and you go twice a week for six weeks, that’s 12 sessions at $30 each — $360 out of pocket. Over a longer course of therapy, the numbers climb.
Medigap plans vary in what they cover, so check your specific plan’s benefits. Not all supplement plans cover the Part B deductible.
When Does Medicare Stop Covering Physical Therapy?
Coverage ends when the therapy is no longer considered skilled and medically necessary. This is a clinical judgment, not a fixed timeline.
Medicare defines skilled therapy as care that requires the skills of a licensed therapist. If your condition has plateaued and you can safely perform exercises on your own, continued visits may be considered maintenance therapy. Original Medicare generally does not cover maintenance therapy when no skilled care is needed.
This is a common point of confusion. Some people assume Medicare covers therapy indefinitely as long as a doctor orders it. That’s not how it works. The therapist’s documentation must show that your condition is improving, or that you need skilled intervention to prevent decline.
There’s also a practical limit: if you stop making progress, your therapist may recommend discharge. That doesn’t mean you can’t return later if your condition changes. You can restart therapy with a new referral if a new medical need arises.
What You’ll Actually Pay: A Realistic Look
The 20% coinsurance sounds simple, but the actual dollar amount depends on what Medicare approves for each service. Medicare publishes fee schedules that vary by geographic area and by the specific therapy codes billed.
As a rough illustration — not a quote for your situation — if Medicare approves $100 for a therapeutic exercise session and $120 for manual therapy, and you receive both in one visit, the approved amount might be $220. Your 20% would be $44 for that visit.
Your therapist’s actual charge may be higher than the approved amount. If they accept assignment, they can only bill you for the 20% of the approved amount, not the difference between their charge and what Medicare pays. If they don’t accept assignment, they can charge you up to 15% more than the approved amount, subject to certain limits.
Most physical therapists accept assignment because it simplifies billing and ensures they get paid. But it’s always worth asking.
Does Medicare Cover Physical Therapy in a Skilled Nursing Facility or at Home?
Yes, but the coverage rules differ by setting.
If you’re in a skilled nursing facility after a hospital stay, Medicare Part A may cover your therapy as part of your skilled nursing benefit. This typically requires a qualifying hospital stay of at least three consecutive days as an inpatient, and admission to the facility within 30 days of discharge. Coverage is generally for up to 100 days per benefit period, with cost-sharing that increases after day 20.
If you receive therapy at home, Medicare Part B covers it under the home health benefit if you meet certain criteria: you must be homebound, need skilled care, and have a plan of care ordered by a doctor. The home health benefit has different cost-sharing rules than outpatient therapy.
Outpatient therapy — the kind you get at a clinic — falls under Part B and follows the 80/20 rule described above. The setting matters because the benefit and the cost-sharing are different.
What to Check Before You Start Therapy
Before your first appointment, confirm a few things. Ask if the provider accepts Medicare assignment. If you’re on Medicare Advantage, ask if prior authorization is required and how many visits are approved. If you have a Medigap plan, check whether it covers the Part B deductible and coinsurance.
You can also ask your therapist what the approved amount is for the services they plan to provide. They may not know the exact figure, but they can usually give you a range based on their experience with Medicare billing.
If cost is a concern, ask about a payment plan or whether the clinic offers financial assistance. Some do. Some don’t. It doesn’t hurt to ask.
The bottom line: Medicare covers physical therapy when it’s medically necessary, and your share is typically 20% after the deductible. The visit limit isn’t a number — it’s a clinical judgment about whether you still need skilled care. Understanding that distinction helps you plan both your treatment and your budget.
Frequently Asked Questions
Does Medicare pay for physical therapy in full?
No. Original Medicare pays 80% of the approved amount after you meet your Part B deductible, and you pay the remaining 20%. Some Medicare Advantage plans may have different cost-sharing, including flat copays.
Is there a limit on how many physical therapy visits Medicare covers?
There is no hard cap on visits, but there is a soft spending threshold — $2,330 in 2024 — that triggers a medical necessity review. Coverage continues as long as your therapist documents that skilled care is still needed.
Does Medicare Advantage require prior authorization for physical therapy?
Many Medicare Advantage plans do require prior authorization before you start therapy, and some limit the number of visits approved at a time. Check your specific plan’s rules before your first appointment.
What happens if Medicare denies my physical therapy claim?
You have the right to appeal. The denial usually means Medicare determined the therapy was not medically necessary or was maintenance care. Your therapist can provide documentation to support an appeal.
