Quick answer
Yes. Part B covers medically necessary outpatient physical therapy, and there is no yearly dollar cap on what Medicare pays. After the Part B deductible, you generally pay 20% of the approved amount. A doctor or other qualified practitioner must certify your plan of care, and Medicare Advantage plans may use copays, networks or prior authorization instead.

Start With the Question Medicare Asks: Is It Medically Necessary?
Medicare does not pay for physical therapy simply because it would be nice to have. It pays when the care is reasonable and necessary for a medical problem, and when it requires the skills of a therapist. That standard shows up everywhere in the rules, so it helps to understand it before anything else.
In practical terms, the therapy needs to be tied to a diagnosis or a loss of function. A knee replacement, a hip fracture, a stroke, a rotator cuff injury, back pain that limits walking, balance problems that put you at risk for falls, and the weakness that follows a long hospital stay are all common reasons. The therapist evaluates you, sets goals, and builds a plan. Medicare then looks at whether that plan and the visits that follow it make sense for your condition.
What Medicare generally will not cover is exercise for general fitness, a gym membership, or massage on its own. Those are different from skilled therapy even though they can feel similar on a sore day. If a service could be safely done by you or a family member without a therapist’s training, it often falls outside coverage.
What You Pay in Original Medicare
Outpatient physical therapy is a Part B service. Once you have met your annual Part B deductible, which is $283, you pay 20% of the Medicare-approved amount for each visit. Medicare pays the other 80%. There is no separate therapy copay in Original Medicare, and the 20% has no built-in ceiling, which is the same exposure you have with any Part B service.
That means the total depends on how many visits you need and how much Medicare approves for each. A short course of treatment adds up slowly. A long course of therapy, or therapy on top of other care in the same year, can add up faster than people expect. If you have a Medicare Supplement plan, it typically picks up some or all of that 20%, depending on the plan letter. Our pages on Medicare Supplement Plan G and Plan N explain how each one handles Part B coinsurance.
Where you get the therapy matters less for the basic rule than people expect. Outpatient therapy furnished by a hospital is generally paid under the same Medicare fee schedule as therapy in a private office or an outpatient rehabilitation clinic, with the same 20% coinsurance. But the amount Medicare approves, and whether the provider accepts Medicare’s approved amount as full payment, can vary from one provider to the next. If you have a choice, it is reasonable to ask the clinic how it will bill, and whether it accepts assignment, before your first appointment.
The Dollar Threshold You Might Hear About
You may have heard of a “therapy cap.” For years Medicare put a hard annual limit on outpatient therapy payments, and people had to appeal or use an exceptions process to go beyond it. Congress removed that hard cap in 2018. Medicare.gov now states that there is no limit on how much Medicare pays for medically necessary outpatient therapy in a calendar year.
What replaced the cap is a threshold. Once your therapy spending for the year passes a set dollar amount that Medicare adjusts annually, your therapist must add a code, called a KX modifier, to the claim to attest that the services are still medically necessary and documented. There is also a higher threshold at which Medicare may select claims for a closer look. Neither threshold stops your care. They are checkpoints, and they mostly affect your provider’s paperwork. But it is a good reason to make sure your therapist’s notes clearly explain why you still need skilled care as the weeks go on.
Certification and the Plan of Care
For Medicare to pay, three things need to line up, according to CMS’s benefit policy manual. First, there must be a written plan of care, which at a minimum lists your diagnoses, your long-term treatment goals, and the type, amount, duration and frequency of the therapy. The therapist who will treat you can write that plan, or a physician or other qualified practitioner can. Second, a physician or a qualified practitioner such as a nurse practitioner, physician assistant or clinical nurse specialist must certify the plan, which means signing off that you need the therapy and are under a doctor’s care. Third, the plan has to be recertified when it runs out or changes significantly, and a certification can cover up to 90 days at a time.
In real life this often happens quietly in the background. The clinic sends the plan to your doctor for a signature, and you may never see the form. The first certification is generally expected within 30 days after treatment begins. It can become a problem if the signature is missing or late, so if your claims are being denied or your therapist mentions paperwork, a short call to your doctor’s office can solve it.
Medicare’s manual says there is no Medicare requirement for a formal doctor’s order, although many clinics ask for one as a matter of routine. Some states also let you see a physical therapist without a referral. Whatever your state allows, Medicare payment depends on the plan of care being certified, so ask the clinic how it handles this before you book and you are not surprised later.
Maintenance Therapy Counts Too
A common belief is that Medicare stops paying once you stop improving. That is not the rule. As the result of a court settlement known as Jimmo v. Sebelius, CMS has made clear that coverage depends on whether you need skilled care, not on whether you are getting better. Skilled therapy can be covered to maintain your current condition or to slow decline, as long as a therapist’s skills are required to carry it out safely and effectively.
For someone with Parkinson’s disease, a long-term neurological condition, or chronic joint disease, this matters. If you have been told that Medicare will not pay because you have “plateaued,” it is worth asking the therapist to document why skilled care is still necessary, and, if a claim is denied, asking about your appeal rights. Our guide to what to do if you are denied describes how appeals work in Medicare Advantage, and Original Medicare has its own appeal process described on the denial notice.
Other Settings: Home, Facilities and Hospitals
| Where you get therapy | Which part of Medicare | What to expect |
|---|---|---|
| Therapist’s office or outpatient clinic | Part B | Deductible, then 20% of the approved amount |
| Hospital outpatient department | Part B | Generally the same 20% of the approved amount |
| At home through a home health agency | Home health benefit | Requires being homebound and a doctor’s certification |
| Skilled nursing facility after a qualifying hospital stay | Part A | Fully covered for the first 20 days, then daily coinsurance |
Physical therapy can happen in several places, and the part of Medicare that pays depends on where you are.
- Outpatient clinic or office: Part B, as described above.
- At home through a home health agency: Physical therapy is one of the skilled services that can qualify you for Medicare home health, but only when you meet the homebound requirement and a doctor certifies that you need it. Our post on Medicare and home health care walks through those requirements.
- Skilled nursing facility: After a qualifying inpatient hospital stay of at least three days, Part A can cover a stay in a skilled nursing facility, including therapy. The first 20 days are fully covered, and from day 21 to day 100 you pay a daily coinsurance, which is $217 per day. Note that time spent in the hospital under observation status does not count toward the three days, which is worth confirming with the hospital.
- Inpatient rehabilitation facility or hospital: Therapy is part of the overall Part A stay, and the Part A deductible of $1,736 applies per benefit period.
If you need therapy after a stroke or joint replacement, your care team will usually help you choose among these. Each setting has different cost-sharing and different eligibility rules, so ask the discharge planner what Medicare is expected to cover and for how long.
What Changes With Medicare Advantage
A Medicare Advantage plan has to cover everything Original Medicare covers, which includes medically necessary physical therapy. But the way you pay and the way you get access is different, and that is where people notice the contrast.
Instead of 20% coinsurance, most Advantage plans charge a flat copay per visit. That can feel more predictable. Advantage plans also have an annual out-of-pocket maximum, which is something Original Medicare does not have on its own. We explain that in our post on Medicare Advantage out-of-pocket maximums.
The trade-off is access rules. Many plans require you to use therapists in their network, and some require prior authorization before a course of therapy or after a set number of visits. A therapist you like may be outside the network. Before you start, check whether your clinic is in the network, whether you need approval, and whether there is a visit limit. Our guide on how to check a plan’s network shows how to do that.
Neither approach is automatically better. Original Medicare with a Medigap plan offers wide choice of providers and little cost per visit, in exchange for a monthly premium. Advantage can have low or no premium and a predictable copay, in exchange for network and authorization rules. Which fits depends on how often you expect to need care and how much flexibility you want. Some Advantage plans also include fitness benefits through a gym or senior program, though the details vary a lot by plan, so check the Evidence of Coverage.
Practical Steps Before Your First Appointment
A few questions up front can save you from billing surprises.
- Is the therapist enrolled in Medicare, and does the office accept Medicare payment as full payment?
- If you have Medicare Advantage, is the clinic in your network, and does the plan require authorization or limit the number of visits?
- Is the plan of care going to be certified by your doctor, and does the clinic handle sending it?
- Will any part of the bill fall outside Medicare’s approved amount, for example if the provider does not accept assignment?
- How many visits do they expect you to need, and what are the goals for ending or reducing therapy?
If you are also considering chiropractic care for back or neck pain, keep in mind that Medicare covers it in a much narrower way than physical therapy. Our post on Medicare and chiropractic care shows where the line is drawn.
Frequently Asked Questions
Is there a limit on how many physical therapy visits Medicare covers?
Original Medicare does not set a visit limit or a yearly dollar cap for medically necessary outpatient therapy. A dollar threshold triggers extra documentation from your therapist, but it does not stop coverage. A Medicare Advantage plan may have its own rules, so check your plan documents.
Do I need a referral to get physical therapy with Medicare?
Medicare requires that a physician or other qualified practitioner certify your plan of care. Some states let you see a therapist first, but the certification is still needed for Medicare to pay. The clinic usually handles this with your doctor.
How much does Medicare pay for physical therapy?
After you meet the Part B deductible, Medicare pays 80% of the approved amount and you pay 20%. A Medigap policy may cover some or all of that 20%. Medicare Advantage plans commonly use a copay instead.
Does Medicare cover physical therapy at home?
It can, in two ways. Home health physical therapy is covered if you are homebound and meet other requirements. Outpatient therapy can sometimes be provided at your home when you are not eligible for home health. Ask the therapist how the visit would be billed.
Will Medicare pay for therapy if I am not improving?
It can. Coverage depends on whether you need skilled care to maintain your condition or slow decline, not on whether you are improving. Your therapist needs to document why the skilled care is necessary.
