Physical Therapy and Medicare Coverage: What You Pay in 2026

Yes, Medicare covers physical therapy when it is medically necessary. Under Original Medicare, Part B helps pay for outpatient physical therapy if your doctor or another allowed provider certifies that you need it. After you meet the Part B deductible, you pay 20% of the Medicare-approved amount. There is no yearly dollar limit on what Medicare will pay for care that is medically necessary.

That is the short version. The details decide your bill: where you get therapy, which part of Medicare pays, what “medically necessary” means on paper, and whether you have a Medicare Advantage plan or a Medigap policy. This guide walks through each one, written for people in Bend and across Central Oregon who are on Medicare or about to be.

TL;DR

  • Part B covers medically necessary outpatient physical therapy. You pay 20% of the Medicare-approved amount after the annual Part B deductible.
  • Medicare’s old annual “therapy caps” were repealed in 2018. A 2026 threshold of $2,480 now triggers extra documentation, not a cutoff.
  • Part A covers therapy during an inpatient rehab stay or a qualifying skilled nursing facility stay. Home health therapy requires that you be homebound.
  • Medicare Advantage plans must cover what Original Medicare covers, but copays, networks and prior authorization rules can differ.
  • Wellness, general fitness or maintenance exercise without a treatment goal does not meet Medicare’s definition of necessary therapy.

What Medicare means by “medically necessary” physical therapy

Medicare does not pay for physical therapy just because it would be good for you. It pays when the therapy treats an illness or injury and your care team can show it.

The federal rules spell this out. Covered therapy must relate directly to a treatment plan designed to treat an illness or injury, with measurable, objective goals recorded in your clinical record. Services aimed at general physical welfare or overall fitness, rather than a specific condition, do not count as necessary therapy.

In practice, these situations usually qualify:

  • Recovery after a hip, knee or shoulder replacement
  • Rehabilitation after a stroke, fall or fracture
  • Treatment for back or neck pain tied to a diagnosed condition
  • Therapy to manage a chronic condition when the therapist’s skills are needed to do it safely and effectively

Two things must be in place. First, a doctor or an allowed provider such as a nurse practitioner, clinical nurse specialist or physician assistant must certify that you need therapy. Second, the care must be delivered by a qualified physical therapist, or an appropriately supervised assistant, under a written plan of treatment. The therapist writes the plan, and your doctor or allowed provider reviews and certifies it.

A practical tip: ask your therapist, before the first visit, what your goals are and how progress will be measured. Those goals are what Medicare looks for if a claim is ever questioned.

Which part of Medicare pays, by setting

Where you receive therapy decides which part of Medicare is billed. Here is the overview.

Setting Medicare part Key condition What you pay (2026)
Outpatient clinic or therapist’s office Part B Certified as medically necessary Part B deductible, then 20% of the approved amount
Inpatient rehabilitation facility Part A Admitted to a hospital rehab unit or facility $0 for days 1 to 60, then daily amounts
Skilled nursing facility Part A Qualifying hospital stay of at least 3 consecutive days $0 for days 1 to 20, $217 per day for days 21 to 100
Your home Home health benefit Under a doctor’s care and homebound See our home health guide

Outpatient therapy under Part B

This is what most people mean by physical therapy: appointments at a clinic, a hospital outpatient department or a therapist’s office. Part B pays 80% of the approved amount once you meet the deductible. You pay the other 20%. The 2026 Part B deductible is $283, and the Part B premium comes out of your monthly Social Security check or is billed separately. Our guide to the 2026 Part B premium explains how that works.

One point trips people up. “Approved amount” is what Medicare has decided the service is worth. If your therapist accepts assignment, they agree to that amount. If they do not, they can charge more, and you may face extra costs. Our explainer on Medicare excess charges covers what that costs and how to avoid it. Always ask a clinic whether it accepts Medicare assignment before you book.

Inpatient rehabilitation under Part A

If you are admitted to a hospital-based inpatient rehabilitation facility or unit, therapy is part of that inpatient stay. Part A pays, subject to the 2026 deductible of $1,736 per benefit period. After that, you pay $0 a day for days 1 to 60, $434 a day for days 61 to 90, and $868 per lifetime reserve day for days 91 to 150. After day 150 you pay all costs. Our Part A coverage guide explains benefit periods in plain terms.

Skilled nursing facility therapy

Many people do their first weeks of rehab in a skilled nursing facility after surgery or a hospital stay. Part A covers therapy there when the services are reasonable, necessary and ordered by a doctor, and after a qualifying hospital stay of at least 3 consecutive days. In 2026 you pay $0 for the first 20 days and $217 per day for days 21 to 100, and all costs after day 100. One detail matters a lot: time spent in the hospital under “observation” status may not count as an inpatient stay. Ask the hospital which status you have. Our guide to skilled nursing coverage goes through the numbers.

Therapy at home

Medicare’s home health benefit covers physical therapy if you are eligible, under a doctor’s care and homebound. CMS also stresses that skilled therapy at home is covered only when your condition is complex enough that a qualified therapist or assistant must perform it to keep it safe and effective. If you can easily get to a clinic, outpatient Part B therapy is the usual route. For the full rules, see our home health coverage guide.

A worked example: what 20% looks like

Say you have knee replacement surgery and your therapist recommends outpatient therapy twice a week. Suppose Medicare’s approved amount for a visit is a round $100. This is an illustration only, since real approved amounts vary by service and location.

  • If you have already met your Part B deductible for the year, Medicare pays $80 and you owe $20 per visit.
  • Twelve visits would mean $240 from you and $960 from Medicare.
  • If you have not met the deductible, you pay the full approved amount until you do, then 20% after that.

Some services in a single visit are billed together. When you receive more than one “always therapy” service on the same day, a 50 percent reduction applies to the practice expense part of the second and later services. It affects how the clinic is paid, and it is built into the approved amount, so you do not need to calculate it yourself.

Because Part B has no out-of-pocket maximum under Original Medicare, 20% of a long course of treatment adds up. That is where supplemental coverage matters, which we cover below.

A worked example: what 20% looks like

Therapy caps: what happened to them

You may have heard about a dollar limit on Medicare therapy. It did exist, and it caused real trouble for people who needed long rehab. The Bipartisan Budget Act of 2018 repealed the therapy caps. Today, there is no limit on how much Medicare pays in a calendar year for medically necessary outpatient therapy.

What remains are thresholds. They work as checkpoints for paperwork, not as ceilings:

  • $2,480 in 2026. Once your therapy claims pass this amount for physical therapy and speech-language pathology combined, your provider must add the KX modifier to claims to attest that the services are medically necessary. Occupational therapy has its own $2,480 threshold.
  • $3,000. Claims above this amount can be selected for a targeted medical review rather than every claim being reviewed automatically.

CMS describes these thresholds as markers for required medical necessity documentation rather than financial limits. If you cross $2,480, you do not lose coverage. Your therapist simply has to document why continued care is necessary. Medical review is a familiar idea in other insurance settings too, and this overview of utilization review shows how reviewers weigh documentation against treatment decisions.

What an ABN means for you

Sometimes a therapist believes Medicare may not pay for a service. In that case, the provider must give you an Advance Beneficiary Notice of Noncoverage before the service. Providers must issue an ABN before services that are not considered medically necessary. Without one, they generally cannot bill you for those services.

An ABN is not a way to pass costs to you just because you reached a threshold. Medicare says the notice is strictly for services considered not medically necessary. If you are handed one, read it, ask what specifically is not covered and why, and decide whether to proceed. You can still receive the service and appeal later.

Physical therapy with Medicare Advantage

If you have a Medicare Advantage (Part C) plan, the plan covers physical therapy, but the rules can look different from Original Medicare. Plans may have different out-of-pocket costs, network requirements and prior authorization rules for therapy. In practice, that often means:

  • A fixed copay per visit instead of 20% coinsurance
  • A network of therapists you must use, or pay more to leave
  • Prior authorization or a referral before therapy starts, or after a set number of visits

Before you start therapy under a Medicare Advantage plan, check your plan’s Evidence of Coverage, call the number on your member card, and confirm that your therapist is in network. Open enrollment is also a chance to change plans if therapy access is a problem. Our Medicare Advantage open enrollment guide explains the window and the rules.

Paying less: Medigap and plan reviews

With Original Medicare, the 20% coinsurance is the main cost that adds up during therapy. Many people use a Medicare Supplement (Medigap) policy to help with cost sharing. If you have a Medigap plan, ask the carrier how your plan treats Part B coinsurance before you start a long course of therapy. You can see how the plan types are organized on our Medicare Supplement plans page.

If you are paying a lot for a Medigap policy you bought years ago, it may be worth a fresh look. Oregon has rules that let some people change Medigap plans without a new medical review, and we help people in Central Oregon check whether they qualify. A yearly Medicare plan review is the easiest time to do that, since your health needs, such as ongoing therapy, may have changed.

Perspective

Most of the physical therapy questions we hear in Bend start the same way: a neighbor had surgery, a knee gave out on a ski season, or a spouse took a fall, and suddenly there is a stack of paperwork. People worry about a limit on visits. Usually, the real issue is smaller and more fixable: whether the clinic takes Medicare assignment, whether a plan needs prior authorization, or whether the 20% will catch them off guard.

Our approach is education first. We explain how Parts A, B, C and D fit together, we point out the deadlines that matter, and we let you decide. A consultation with us costs nothing, and it is much easier to ask about therapy coverage before a surgery than after the first bill arrives.

If your plan no longer fits the care you need, we can walk through your options with you in person or remotely, without pressure.

Questions to ask before you start therapy

A few checks up front prevent most billing surprises:

  1. Does the therapist accept Medicare assignment? If not, ask what you could be charged beyond the approved amount.
  2. Who certified the plan of care? Your doctor or an allowed provider must sign off.
  3. What are my measurable goals? They should be written in your record.
  4. Do I have a Medicare Advantage plan? If yes, confirm network status and any prior authorization.
  5. Is any part of this service likely not covered? If so, ask for the ABN in advance and ask what is not covered.
  6. Do I have supplemental coverage? Check how it handles Part B coinsurance.

Keep your Medicare Summary Notices. If a claim is denied, you have the right to appeal, and the notice explains how.

Physical therapy often comes alongside other care. If you also see a chiropractor, our guide to Medicare chiropractic coverage explains what Part B does and does not pay for. If a fall or injury sends you to the hospital first, see how ambulance rides and emergency room visits are billed. If you are still deciding when to enroll, our step-by-step guide for turning 65 lays out the timeline.

FAQ

Does Medicare cover 100% of physical therapy?

No. For outpatient therapy under Original Medicare, you pay 20% of the Medicare-approved amount after the Part B deductible. A Medigap policy or other supplemental coverage may help with that share, depending on the plan. Inpatient rehab and skilled nursing stays are billed under Part A with different cost sharing.

How many physical therapy sessions will Medicare pay for?

Medicare sets no fixed number of visits and no yearly dollar limit for medically necessary outpatient therapy. Your therapist must document that care is still needed. Once claims pass the $2,480 threshold in 2026, the provider adds the KX modifier to confirm medical necessity.

Do I need a referral or a doctor’s order?

Your doctor or an allowed provider, such as a nurse practitioner or physician assistant, must certify that you need therapy and review your plan of care. Some Medicare Advantage plans also require a referral or prior authorization, so check with your plan before booking.

Does Medicare cover physical therapy at home?

Yes, under the home health benefit, if you are under a doctor’s care and homebound, and your condition requires the skills of a therapist. If you can get to a clinic with reasonable effort, outpatient therapy under Part B is usually the route.

Are Medicare therapy caps still in effect?

No. Congress repealed the annual therapy caps in 2018. Today there are payment thresholds that require extra documentation and can lead to targeted medical review, but they do not stop Medicare from paying for necessary care.
