Medicare covers physical therapy, but the number of visits depends on which part of Medicare you have and whether your therapy is medically necessary

Medicare Part B covers outpatient physical therapy at a rate of 80 percent after you meet your yearly deductible. You pay the remaining 20 percent. There is no set limit on the total number of visits Medicare will cover in a year — instead, Medicare requires that each visit be medically necessary, meaning your doctor has ordered it to treat a specific condition and your therapist documents that you are making progress toward a functional goal.

If you have Original Medicare (Part A and Part B), you can receive physical therapy at a clinic, hospital outpatient department, or your home. If you are in a Medicare Advantage plan (Part C), your coverage works differently: your plan sets its own visit limits and may require you to use in-network providers. The amount you pay out of pocket varies by plan.

Key Takeaways

  • Original Medicare Part B covers physical therapy with no annual visit cap, but each visit must be medically necessary and documented as making progress toward a functional goal.
  • You pay 20 percent of the Medicare-approved amount for each visit after meeting your Part B deductible, which changes yearly.
  • Medicare Advantage plans set their own visit limits and copays, so you must check your plan documents to know what you will owe.
  • Your doctor's order and your therapist's progress notes are what determine whether Medicare continues to cover your visits, not a predetermined number.
  • If Medicare denies coverage for a visit, you have the right to appeal the decision within 120 days.

How Original Medicare Part B Counts Physical Therapy Visits

Original Medicare does not say "you get 30 visits" or "you get 60 visits." Instead, it uses a medical necessity standard. Your physical therapist must document that you are working toward a specific, measurable goal — such as regaining the ability to walk after a hip replacement, or improving balance to prevent falls. Medicare reviews these notes to confirm the therapy is helping you improve.

In practice, this means the number of visits you receive depends on your condition and your progress. Someone recovering from knee surgery might need 12 visits over six weeks. Someone managing chronic arthritis might receive ongoing therapy over several months. The key is that your therapist must show improvement or maintenance of function with each visit. If you stop making progress, Medicare may deny further visits.

Your doctor does not have to request a specific number of visits upfront. Instead, your therapist works with your doctor to adjust the treatment plan as you improve. If your therapist believes you need more visits, they can request them; if Medicare denies the request, your therapist can appeal on your behalf.

What You Pay Under Original Medicare

After you meet your yearly Part B deductible (the amount changes each year), Medicare pays 80 percent of the approved amount for each physical therapy visit. You pay the remaining 20 percent. The approved amount is set by Medicare, not by the therapist's full charge, so your out-of-pocket cost is based on Medicare's rate, not the clinic's bill.

If you see a therapist who does not accept Medicare assignment, you may owe more. A therapist who accepts assignment agrees to charge only the Medicare-approved amount. A therapist who does not accept assignment can charge up to 15 percent more than the approved amount, and you are responsible for that difference on top of your 20 percent coinsurance.

To avoid surprise bills, ask your therapist's office whether they accept Medicare assignment before your first visit. You can also search for in-network providers on the Medicare website or call Medicare directly at 1-800-MEDICARE.

Medicare Advantage Plans and Physical Therapy Coverage

If you are enrolled in a Medicare Advantage plan, your physical therapy coverage is determined by your specific plan, not by the rules above. Some plans cover a set number of visits per year — for example, 20 or 30 visits. Others use the same medical necessity standard as Original Medicare. Some plans require prior authorization, meaning your doctor or therapist must get approval from the plan before you start therapy.

Your plan documents spell out the details. You can find this information in your plan's Summary of Benefits and Coverage, which was mailed to you when you enrolled. You can also call the customer service number on your insurance card and ask: "How many physical therapy visits does my plan cover per year?" and "Do I need prior authorization?"

Copays for physical therapy in Medicare Advantage plans vary widely. Some plans charge a flat copay per visit (for example, $25 or $40). Others charge coinsurance, meaning you pay a percentage of the cost. A few plans cover physical therapy with no copay. Check your plan documents or call your plan to find out what you will owe.

Physical Therapy in a Hospital, Clinic, or at Home

Medicare covers physical therapy in three settings: an outpatient hospital department, an outpatient clinic, and your home. The coverage rules are the same across all three settings — Medicare pays 80 percent after your deductible, and you pay 20 percent — but the approval process differs slightly.

If you receive therapy in a hospital outpatient department or clinic, your therapist submits claims to Medicare directly. If you receive therapy at home, your doctor must order home health services, and a home health agency coordinates your care. Home health therapy is covered under Part A (if you are homebound) or Part B, depending on your situation. Ask your doctor which route is right for you.

Some people may have access to for therapy in a skilled nursing facility after a hospital stay. This therapy is covered under Part A as part of your skilled nursing care, not as a separate service. You pay a copay per day for the facility, not per therapy visit.

When Medicare Stops Covering Physical Therapy Visits

Medicare will stop covering your physical therapy visits if your therapist documents that you are no longer making progress toward your functional goal. This does not mean you have to improve dramatically with each visit — it means your therapist must show that therapy is still helping you, even if the improvement is small.

If Medicare denies a visit or stops covering your therapy, your therapist will send you a notice called an Advance Beneficiary Notice (ABN). This notice tells you that Medicare may not cover the next visit and explains why. You can choose to continue therapy and pay out of pocket, or you can stop. If you disagree with Medicare's decision, you have 120 days to file an appeal.

To appeal, you can ask your therapist to submit additional documentation showing that you are still making progress, or you can contact Medicare directly. Your therapist can help you with this process. Many appeals are successful, especially if your therapist can show concrete improvements in your function.

How to Find Out Your Specific Coverage

The best way to know exactly how many visits you can receive is to contact Medicare or your plan before you start therapy. If you have Original Medicare, call 1-800-MEDICARE and ask: "How many physical therapy visits will Medicare cover for my condition?" Be ready to describe your condition and what your doctor ordered.

If you have a Medicare Advantage plan, call the number on your insurance card and ask the same question. Ask whether you need prior authorization and whether the therapist you want to see is in-network. If you are considering a specific clinic or therapist, ask the office staff to verify your coverage — they do this regularly and can often tell you within a day or two.

You can also check your coverage online. Original Medicare beneficiaries can log into Medicare.gov and search for providers. Medicare Advantage members can use their plan's website or app to search for in-network therapists and see copay amounts.

Frequently Asked Questions

Does Medicare cover physical therapy for arthritis or chronic pain?

Yes, if your doctor orders it and your therapist documents that it is helping you maintain or improve your function. Medicare covers therapy for chronic conditions, but the visits must still meet the medical necessity standard. If you have not improved or maintained your baseline after several visits, Medicare may deny further coverage.

What if my physical therapist charges more than Medicare approves?

If your therapist accepts Medicare assignment, you owe only your 20 percent coinsurance based on Medicare's approved amount. If your therapist does not accept assignment, they can charge up to 15 percent more, and you are responsible for that extra amount. Always ask whether a therapist accepts assignment before your first visit.

Can I switch physical therapists if I do not like mine?

Yes. You can change therapists at any time. Your new therapist will need a new order from your doctor, and they will start documenting your progress from that point forward. Switching therapists does not reset your visit count under Original Medicare, since there is no annual limit — but it may affect your progress documentation if you are in a Medicare Advantage plan with a visit cap.

What happens if I reach my visit limit in a Medicare Advantage plan?

If your plan has a visit cap and you reach it, Medicare will not cover additional visits unless your plan allows an exception. Some plans allow your doctor to request additional visits if you are still making progress. Ask your plan whether exceptions are possible, and have your therapist submit a request if you need more visits.

Do I have to pay for physical therapy out of pocket if Medicare denies it?

No, you do not have to pay. If Medicare denies coverage, your therapist will send you an Advance Beneficiary Notice before the visit. You can choose to stop therapy, or you can pay out of pocket if you want to continue. You are not obligated to pay for a visit Medicare has denied.
