Physical Therapy Coverage in Medicare: What Part B Pays

Physical Therapy Coverage in Medicare: What Part B Pays

Medicare covers physical therapy when it is medically necessary. Original Medicare Part B helps pay for outpatient therapy, and after you meet the Part B deductible you pay 20% of the Medicare-approved amount. There is no dollar limit on what Medicare will pay in a calendar year for medically necessary outpatient physical therapy. The rules that matter are not about how many visits you get. They are about whether your therapy is ordered, documented and tied to a real medical need.

Below is how that works in practice, what you pay, how home therapy and rehab stays differ, and what changes if you have a Medicare Advantage plan.

TL;DR

• Part B covers medically necessary outpatient physical therapy. After the deductible, you pay 20% of the Medicare-approved amount.
• No yearly cap on what Medicare pays, but your therapist must show your care is necessary, and a higher spending level triggers extra documentation.
• Therapy at home requires you to qualify for Medicare home health, which includes being homebound.
• Inpatient rehab and skilled nursing stays fall under Part A, with different costs.
• Medicare Advantage plans must cover what Original Medicare does, but copays and networks vary by plan, so check yours before you book.

What Medicare means by physical therapy

Medicare Part B helps pay for medically necessary outpatient physical therapy if you are eligible. In everyday terms, that means treatment to restore or maintain function after an injury, surgery, illness or a condition such as arthritis, a stroke or a fall. Common examples are therapy after a knee or hip replacement, rehab after a shoulder injury, balance and gait training, and treatment for back or neck pain.

The key word is “necessary.” Medicare does not pay for therapy that is only about general wellness. Services related solely to general physical welfare or overall fitness are not covered. A gym-style program, or a set of exercises handed to everyone regardless of condition, will not qualify.

What makes therapy “medically necessary”

This is where most coverage questions are decided. Medicare’s billing guidance says services must be individualized to your specific medical needs, and that “packaged” or predetermined programs are not covered. In practice, a covered course of therapy usually has these parts:

1. A diagnosis or functional problem. Something specific, such as trouble walking after surgery or limited shoulder motion after an injury.
2. A plan of care. Your therapist sets goals and a schedule. Your doctor or another allowed provider must certify that you need the therapy.
3. Measurable goals. Under federal rules, goals must be measurable and relate directly to your illness or injury, backed by objective functional measurements. A goal like “walk 150 feet with a cane without stopping” works. “Feel better” does not.
4. Objective notes. Medicare’s billing guidance expects therapy notes to use things like pain scales or functional metrics and to be consistent with standard clinical practice.
5. Skilled care. The treatment must be complex enough that it needs a qualified therapist, or someone working under their supervision.

This documentation is mostly your therapist’s job, but it helps to know it exists. If a clinic tells you that your progress notes show a plateau, ask what the next measurable goal is and whether continued therapy is still expected to help.

Improvement is not the only test

Many people assume Medicare stops paying once you stop improving. The question is whether the skilled care of a therapist is still necessary to keep your condition from getting worse or to maintain function. Your therapist documents that need. If you are told coverage is ending, ask for the reason in plain terms and ask your doctor whether they agree.

Who has to order or oversee your therapy

Physical therapy must be ordered by a physician and provided by a qualified therapist or under their supervision. Outpatient physical therapy can be furnished in a few settings: a provider such as a hospital outpatient department or rehab agency, a therapist in private practice, or “incident to” a physician’s service under specific conditions.

When you choose a clinic, ask two questions before your first visit:

• Do you accept Medicare assignment?
• Will you bill Medicare directly?

If the answer to either is no, you could face higher bills or paperwork.

What you pay under Original Medicare

After your Part B deductible, Medicare pays its share of the approved amount and you pay 20%. There is no copay structure to learn beyond that for most office-based therapy. Here is how the pieces fit:

The coinsurance has no yearly ceiling in Original Medicare. Twenty percent of a long course of therapy adds up, and that is why many people pair Original Medicare with a Medicare Supplement (Medigap) plan. Medigap policies are sold by private insurers and can pay some or all of the 20% your Part B coverage leaves to you, depending on the plan letter. A plan that covers the Part B coinsurance can make a long course of therapy after a joint replacement far more predictable.

Hospital outpatient departments can cost more

Where you get therapy affects the bill. For outpatient hospital care, you usually pay 20% of the Medicare-approved amount for provider services plus a copayment to the hospital, and you may pay more than for the same service in a doctor’s office. If you have a choice between a hospital outpatient department and an independent clinic that takes Medicare, ask each for an estimate.

Is there a limit on physical therapy visits?

Not on the dollar amount Medicare pays. Medicare will pay for medically necessary outpatient therapy with no limit in a calendar year. There is also no fixed number of visits.

What does exist is a spending threshold that triggers extra scrutiny. Medicare administrators publish a per-beneficiary KX modifier threshold, which for 2026 is $2,480 for physical therapy and speech-language pathology combined. Once your therapy costs pass that point in the year, your therapist has to attach a modifier to the claim confirming the services are still medically necessary and documented. A separate medical review threshold of $3,000 stays in place through 2028 per the same page, and claims above it can be selected for review.

For you, this is not a cutoff. It is a signal that your therapist needs to show the record supports continued care. If you are in a long course of treatment, ask your clinic whether you are close to the threshold and whether the notes are ready.

When Medicare may not pay: the ABN

If a therapy provider believes Medicare will not consider a service medically necessary, they must give you an Advance Beneficiary Notice of Noncoverage (ABN) before they deliver it. If you sign and go ahead, you are responsible for the full cost.

A few rules of thumb:

• An ABN is not a denial. It is a warning that one may come.
• Ask what specifically makes the provider think the service will not be covered.
• You can decline the service, or accept it and ask the provider to still bill Medicare so you can appeal a denial.
• Never sign a blank ABN.

Physical therapy at home

Home therapy is covered through Medicare’s home health benefit, not as a general convenience. To qualify, you must be homebound, under the care of a doctor or allowed provider, and receive services under a care plan they establish and review. The provider must certify that you need physical therapy or another qualifying service, as Medicare’s home health booklet explains.

The therapy itself must be complex enough to need a qualified therapist, and be a specific, safe and effective treatment for your condition. Under federal rules, a qualified therapist must provide the therapy and reassess you at least every 30 calendar days.

If you can leave home without great effort, such as to drive to a clinic, you probably do not meet the homebound test. In that case, outpatient therapy is the usual route. Some outpatient clinics will treat you at home as a mobile service billed under Part B, so ask directly rather than assuming home health is the only way.

Therapy after a hospital stay: inpatient rehab and skilled nursing

The rules change when you are admitted.

Inpatient rehabilitation facility. Part A covers medically necessary inpatient rehabilitation care, including therapy in designated facilities or units. For 2026, beneficiaries pay a $1,736 deductible for days 1 to 60 of a benefit period, with $0 daily coinsurance for those days, according to the same Medicare page.

Skilled nursing facility (SNF). Therapy in a nursing facility after a hospital stay is a separate benefit with its own costs, and it generally depends on how you were classified in the hospital. A stay billed as “observation” rather than “inpatient” can change whether SNF care is covered at all. Our guide to observation versus inpatient status and SNF costs explains the difference and the question to ask the hospital before you leave.

If you or a parent is heading for a hospital stay, ask early: “Am I admitted as an inpatient or under observation?” It is one of the most useful questions a family can ask.

Original Medicare versus Medicare Advantage

Everything above describes Original Medicare. People with a Medicare Advantage plan must check with their plan for coverage details, because terms and provider networks may differ.

In practice, here is what to compare:

Neither is automatically better. If you expect a lot of therapy, a plan with a low per-visit copay and an out-of-pocket maximum can be cheaper than Original Medicare alone. Original Medicare with a Medigap plan gives you freedom to choose a therapist anywhere that accepts Medicare, with predictable costs. The better fit depends on your doctors, your health and how much you value a wider choice of providers. If you also qualify for Medicaid, costs shift again, which we cover in Medicaid versus Medicare costs.

How to check your therapy coverage before you start

1. Get the order. Ask your doctor for a referral or order that names the condition and the therapy needed.
2. Confirm the clinic takes Medicare. Ask if they accept assignment and bill Medicare directly.
3. Ask what a visit will cost you. After the deductible, that is 20% in Original Medicare. With Medicare Advantage, ask for the plan’s copay and whether you need prior authorization.
4. Ask about the goals. Request your therapist’s measurable goals and the expected length of care.
5. Watch for an ABN. Read it, ask questions, and do not sign anything blank.
6. Keep your own records. Save your Medicare Summary Notice and any plan statements so you can spot errors or appeal a denial.

FAQ

Is there a limit on physical therapy for Medicare?

There is no dollar limit on what Medicare will pay in a calendar year for medically necessary outpatient physical therapy. There is also no set number of visits. Your therapist does need to document that care is still necessary, especially once you pass the yearly KX modifier threshold.

How do I qualify for physical therapy at home?

You need to meet the home health requirements. You must be homebound, be under the care of a doctor or allowed provider, and have a care plan they establish and review. The provider must certify that you need physical therapy or another qualifying service. If you are not homebound, outpatient therapy is the usual route.

What do I pay for Medicare physical therapy?

In Original Medicare, you pay the Part B deductible first, then 20% of the Medicare-approved amount. Hospital outpatient departments can add a copayment. A Medigap plan can pay some or all of the 20%, and Medicare Advantage plans set their own copays.

How long will Medicare pay for inpatient rehab?

Medicare Part A covers medically necessary inpatient rehabilitation in designated facilities. In 2026, you pay a $1,736 deductible for days 1 to 60 of a benefit period, with no daily coinsurance during those days. Coverage depends on your care continuing to be medically necessary, so ask the facility to explain your expected length of stay.

Does Medicare Advantage cover physical therapy?

Yes, Medicare Advantage plans cover physical therapy, but the way they do it varies. Costs per visit, networks and prior authorization rules are set by your plan, so check your plan documents or call member services before you start treatment.
