Medicare covers physical therapy at home, but only under specific conditions and through a formal plan ordered by your doctor.

Medicare Part B pays for home physical therapy when a doctor determines you are homebound or have a medical reason you cannot travel to a clinic. The therapy must be medically necessary — ordered as part of a treatment plan for a condition like stroke recovery, joint replacement, or arthritis. Medicare does not cover maintenance therapy or therapy aimed at general fitness.

The process starts with your doctor. They must document that you need skilled physical therapy and cannot reasonably leave home without medical information. Your doctor then refers you to a home health agency that is Medicare-certified. The agency handles the paperwork, schedules the visits, and bills Medicare directly.

Key Takeaways

  • Your doctor must order home physical therapy and state in writing that you are homebound or medically unable to travel to an outpatient clinic.
  • Medicare Part B covers 80 percent of the cost after you meet your annual deductible; you pay the remaining 20 percent.
  • The physical therapist must work through a Medicare-certified home health agency, not as an independent contractor.
  • Coverage ends when your doctor determines the therapy is no longer medically necessary or you no longer meet the homebound requirement.

How Medicare Determines You Are Homebound

Medicare uses a specific definition: you are homebound if leaving home requires supportive information, medical equipment, or considerable and taxing effort due to your condition. This does not mean you never leave home — it means leaving for therapy would be medically risky or require help you do not have available.

Your doctor documents this in the referral. They explain why you cannot attend an outpatient clinic. Common reasons include recent surgery with mobility restrictions, severe arthritis that makes transportation painful, neurological conditions affecting balance, or recovery from a fall or stroke. Medicare reviewers look at the medical record, not your word alone.

If you can leave home for other activities — groceries, church, social visits — Medicare may still cover home therapy if your doctor documents that the effort required for therapy specifically would be harmful. The standard is whether therapy outside the home is medically contraindicated, not whether it is inconvenient.

What Physical Therapy Services Medicare Covers at Home

Medicare covers skilled physical therapy — meaning therapy that requires a licensed physical therapist and is tied to a specific medical condition. This includes range-of-motion exercises after joint replacement, gait training after stroke, balance work to prevent falls, and therapeutic exercises prescribed for arthritis or other diagnoses.

Medicare does not cover therapy that is purely maintenance or preventive. If you have recovered from your condition and the therapist is now working to keep you from declining, that is maintenance therapy and Medicare stops paying. The therapy must be aimed at improvement or restoration of function, not preservation of current ability.

The home health agency coordinates with your doctor to set a treatment plan. The plan states the diagnosis, the specific therapy goals, how many visits per week you will receive, and the expected duration. Medicare reviews this plan and may deny coverage if the goals are not specific enough or the frequency seems excessive for your condition.

How Much Medicare Pays and What You Pay

Medicare Part B covers 80 percent of the approved cost for home physical therapy after you have met your annual Part B deductible. You pay the remaining 20 percent, called coinsurance. The deductible for 2024 is $240, though this amount changes yearly.

The "approved cost" is what Medicare determines is reasonable for your area and condition, not what the home health agency charges. If the agency bills more than the approved amount, they cannot bill you for the difference — that is called balance billing, and it is illegal for Medicare providers.

If you have a Medigap or Medicare Advantage plan, your out-of-pocket costs may be lower. Medigap plans often cover the 20 percent coinsurance. Medicare Advantage plans have their own cost structures and may require copayments instead. Check your plan documents or call your plan to learn your exact cost before therapy begins.

How to Start Home Physical Therapy Through Medicare

The first step is talking to your doctor. Tell them you are having difficulty with mobility, strength, or function, and ask whether home physical therapy might help. Your doctor examines you, reviews your medical history, and decides whether therapy is medically necessary and whether you meet the homebound requirement.

If your doctor agrees, they write a referral and order to a Medicare-certified home health agency. You can ask your doctor which agencies they work with, or you can choose one yourself — your doctor's office can send the referral to any certified agency you select. The agency then contacts you to schedule an initial evaluation.

During the evaluation, the physical therapist assesses your condition, tests your strength and range of motion, and discusses your goals. They develop a treatment plan and submit it to Medicare for review. Medicare typically responds within a few days. Once approved, therapy begins on a schedule your therapist and you agree on.

When Medicare Stops Covering Home Physical Therapy

Medicare coverage ends when your doctor determines that further therapy will not improve your condition, or when you no longer meet the homebound requirement. This is called reaching "plateau" — the point where continued therapy is unlikely to produce meaningful progress.

Your therapist and doctor communicate regularly about your progress. If you are improving steadily, therapy continues. If progress slows or stops, your doctor may discharge you from therapy. You will receive notice before this happens, and you have the right to ask your doctor to reconsider if you believe you can still improve.

If you become able to leave home safely and attend an outpatient clinic, you may no longer meet the homebound requirement. At that point, Medicare will not cover home therapy, though you could pursue outpatient therapy instead if your doctor orders it.

What Happens If Medicare Denies Coverage

If Medicare denies your claim or stops covering your therapy, the home health agency must notify you in writing. The notice explains the reason — usually that the therapy is not medically necessary, you do not meet the homebound requirement, or the goals in your treatment plan are not specific enough.

You have the right to appeal. The home health agency can resubmit the claim with additional medical information from your doctor. Your doctor can write a letter explaining why therapy is still medically necessary or why you remain homebound. This often resolves the denial.

If the appeal is denied, you can request a formal review through Medicare's appeals process. The home health agency can guide you through this, or you can contact Medicare directly at 1-800-MEDICARE. An independent reviewer will examine your medical record and the denial reason.

Frequently Asked Questions

Can I choose any physical therapist, or does it have to be through a home health agency?

It must be through a Medicare-certified home health agency. Medicare does not pay for physical therapy from an independent therapist working alone, even if they are licensed. The agency handles billing, documentation, and coordination with your doctor.

How many visits per week can Medicare cover?

There is no fixed limit, but the number must be medically justified and documented in your treatment plan. Typical ranges are two to three visits per week, though some conditions warrant more frequent therapy. Your doctor and therapist determine the frequency based on your diagnosis and progress.

What if I have a Medicare Advantage plan instead of Original Medicare?

Medicare Advantage plans must cover home physical therapy under the same rules as Original Medicare, but they may have different copayments, require prior authorization, or limit which home health agencies you can use. Contact your plan before starting therapy to learn your costs and any approval steps.

Do I have to be discharged from the hospital to get home physical therapy?

No. You can receive home physical therapy whether you were recently hospitalized or not. Your doctor can order it for any condition where you are homebound and therapy is medically necessary. Hospital discharge is common but not required.

What if my doctor says I am not homebound but I still cannot get to therapy?

Medicare's definition of homebound is specific and medical, not based on transportation difficulty or inconvenience. If your doctor does not document a medical reason you cannot leave home, Medicare will not cover home therapy. You would need to pursue outpatient therapy or discuss with your doctor whether your condition truly prevents travel.
