Medicare covers physical therapy, but only when ordered by a doctor for a medical condition — not for general fitness or wellness.

Medicare Part B pays for physical therapy (PT) when a doctor refers you for treatment of an injury, surgery recovery, or a condition like arthritis or stroke. The therapy must be medically necessary, meaning it treats a specific problem rather than maintains overall health. You pay 20% of the cost after you meet your Part B deductible; Medicare pays the rest.

The catch is that Medicare limits how many visits you can have per year and sets a dollar cap on what it will spend. Those limits change, and they vary depending on whether you're getting therapy in an outpatient clinic, at home, or in a hospital setting. Your doctor and the therapy clinic will know the current limits and whether your condition fits within them.

Key Takeaways

  • Your doctor must order physical therapy for a medical condition; Medicare does not cover it for general fitness or prevention.
  • You pay 20% of the approved cost after meeting your Part B deductible; the rest is covered by Medicare.
  • Medicare sets an annual dollar limit on outpatient PT, and the therapy clinic must track your spending toward that cap.
  • Home-based physical therapy and therapy in other settings may have different limits and approval rules.
  • Your doctor and the therapy provider can tell you upfront whether your condition and number of visits will be covered.

When Medicare Pays for Physical Therapy

Medicare covers PT when a licensed physician — your primary care doctor, a specialist, or a hospital doctor — orders it as treatment for a medical condition. Common reasons include recovery from hip or knee surgery, stroke rehabilitation, arthritis management, balance problems that increase fall risk, and weakness after hospitalization.

The therapy must be medically necessary, which means it treats the condition rather than maintains fitness. If you want PT to stay active or prevent future problems, Medicare will not pay. But if your doctor documents that PT is needed to restore function after an injury or illness, it qualifies.

The physical therapist will evaluate you and create a treatment plan. That plan goes to Medicare for review. If Medicare approves it, you can begin therapy. If Medicare denies it, the clinic will tell you and explain why — usually because the condition does not meet their coverage rules or because the number of visits requested seems excessive for that diagnosis.

How Much You Pay Out of Pocket

After you meet your Part B deductible for the year, you pay 20% of Medicare's approved amount for each PT visit. Medicare pays the remaining 80%. The approved amount is set by Medicare, not by the clinic's full charge, so your 20% is based on that lower figure.

In addition to the per-visit cost, Medicare sets an annual dollar limit on outpatient PT. That limit applies to all outpatient therapy combined — physical therapy, occupational therapy, and speech-language pathology together. The limit changes each year. Your therapy clinic tracks your spending and will tell you when you are approaching the cap. Once you hit it, Medicare stops paying until the next calendar year begins.

If you have a Medigap or Medicare Advantage plan, your out-of-pocket costs may be lower. Medigap plans can cover your 20% coinsurance. Medicare Advantage plans have their own rules and may cover more visits or have different limits. Check your plan documents or call the plan to understand your coverage before you start therapy.

Annual Visit and Dollar Limits

Medicare does not publish a straightforward "you get X visits per year" rule. Instead, it sets a dollar cap on what it will spend on outpatient PT in a calendar year. The cap applies to all outpatient therapy — PT, occupational therapy, and speech therapy combined. The dollar amount changes annually and varies by region slightly, so the clinic must look it up for your specific situation.

The clinic is responsible for tracking your spending toward that cap. They will tell you how many visits you have used and how much of your annual limit remains. If your doctor prescribes 30 visits but the dollar cap would be reached after 20 visits, Medicare will only pay for those 20 unless you request a manual review.

Home-based PT and therapy in other settings (like a hospital or skilled nursing facility) may have different limits or no limit at all. Ask your provider which setting your therapy will be in and what the spending rules are for that setting.

Getting Your Doctor's Referral

You cannot start PT on your own; your doctor must order it. During an office visit, tell your doctor about the problem — pain, weakness, balance issues, or difficulty after surgery — and ask whether PT might help. If your doctor agrees, they will write an order that includes the diagnosis, the type of therapy needed, and how many visits they think you will need.

Bring that order to the physical therapy clinic. The clinic will schedule an evaluation, and the physical therapist will assess you and create a treatment plan. That plan is sent to Medicare for approval. Most approvals come back within a few days, though some take longer if Medicare needs more information.

If Medicare denies the plan, the clinic will contact you and your doctor. Your doctor can appeal the denial or modify the plan to fit Medicare's rules. You have the right to request a manual review if you believe the denial is wrong.

Physical Therapy in Different Settings

Where you receive PT affects which Medicare rules explore. Outpatient PT at a clinic or hospital outpatient department is subject to the annual dollar cap. Home health PT is covered under Medicare Part A (if you are homebound and meet other requirements) and does not count toward the outpatient cap. Skilled nursing facility PT is covered as part of your stay if you were hospitalized first and meet Medicare's criteria.

If you are in a hospital or rehabilitation facility as an inpatient, PT is included in your hospital bill and is not billed separately. Once you are discharged, any PT you receive as an outpatient goes back under the outpatient rules and dollar cap.

Ask your doctor and the therapy clinic which setting makes sense for your situation. Home-based therapy can be convenient if you have mobility problems, but it requires that you be homebound or have difficulty leaving home. Outpatient clinic therapy gives you access to more equipment and may allow more flexibility in scheduling.

What Is Not Covered

Medicare does not cover PT for general fitness, wellness, or prevention — even if your doctor thinks staying active is good for you. If you want to work with a physical therapist to improve balance, build strength, or stay flexible without a specific medical diagnosis, you pay out of pocket.

Medicare also does not cover PT ordered by a non-physician provider, such as a nurse practitioner or physician assistant, in most cases. The order must come from a licensed physician. Some states allow certain advanced practice providers to order PT, but the rules vary, so check with your clinic.

If you reach your annual dollar cap, Medicare stops paying for additional outpatient PT visits that year. You can pay out of pocket to continue, or you can wait until January 1 when the new annual limit begins.

Frequently Asked Questions

Do I need a referral from my primary care doctor, or can a specialist order PT?

Any licensed physician can order physical therapy — your primary care doctor, a cardiologist, an orthopedic surgeon, or any other MD or DO. The order just needs to come from a doctor, not from a nurse or therapist. If you see a specialist for your condition, they can write the PT order directly.

What happens if I use up my annual dollar limit before the year ends?

Once you reach the annual cap, Medicare stops paying for outpatient PT visits. You can continue therapy and pay the full cost yourself, or you can stop and resume in January when the new year's limit begins. Your doctor and therapist can discuss whether it makes sense to pause or continue out of pocket.

Does Medicare Advantage cover physical therapy differently than Original Medicare?

Medicare Advantage plans must cover at least what Original Medicare covers, but many plans offer more visits or lower out-of-pocket costs. Check your plan's coverage documents or call the plan to find out your specific limits and copays before you start therapy.

Can I get physical therapy at home if I am not homebound?

Home-based PT through Medicare's home health benefit requires that you be homebound or have a doctor document that leaving home is medically contraindicated. If you are not homebound, you would receive outpatient PT at a clinic instead, and the outpatient dollar cap would explore.

What if my doctor prescribes more visits than Medicare's dollar limit allows?

The therapy clinic will track your spending and let you know when you are approaching the cap. If your doctor believes more visits are medically necessary, they can request a manual review from Medicare, which may approve additional visits in some cases. Otherwise, you can continue therapy out of pocket or wait for the new calendar year.
