Does Medicare Part B Cover Physical Therapy?
How Medicare Part B Covers Physical Therapy
Medicare Part B physical therapy coverage is a crucial benefit for beneficiaries seeking rehabilitation for injuries, chronic illnesses, or post-surgical recovery. Under current Medicare guidelines, outpatient physical therapy Medicare coverage means that, once you meet the annual Part B deductible of $257 for 2025, Medicare pays 80% of the Medicare-approved amount for covered therapy services. You are responsible for the remaining 20% as physical therapy coinsurance Medicare, unless you have additional coverage such as Medigap or a Medicare Advantage plan.
To be eligible for coverage, your therapy must be ordered or prescribed by a doctor, nurse practitioner, or physician assistant. The provider certifies it as medically necessary physical therapy and develops a written plan of care. This care plan must be reviewed regularly by your provider to maintain ongoing coverage, ensuring that your treatment remains appropriate and effective for your diagnosis or condition.
It’s important to note that while Medicare covers outpatient physical therapy in various settings, the actual out-of-pocket expense may differ based on the therapy location, whether your provider accepts Medicare assignment, and if you have supplemental coverage.
What Qualifies as Medically Necessary Physical Therapy?
For therapy to be covered under Medicare, it must be deemed medically necessary. Medically necessary therapy Medicare services are those considered appropriate for diagnosing and treating an injury, illness, surgery recovery, or managing chronic health conditions such as stroke aftermath, Parkinson’s disease, or joint replacement rehabilitation.
- The therapy must require the skills and expertise of a licensed physical therapist or qualified provider.
- Care must be based on an individual, written treatment plan, clearly outlining therapy goals, the specific procedures, the frequency and anticipated duration of treatments, and expected improvement or maintenance goals.
- Ongoing therapy medical necessity documentation must be supported by objective measurement of functional limitations-this could include strength testing, mobility assessments, or pain scales.
Services like routine massages, gym memberships, or non-specific wellness exercises are not covered, as they do not meet the criteria for medical necessity and are not documented as impactful for the patient’s recovery or functional improvement.

Coverage Limits and Documentation Requirements
Since 2018, there is no annual therapy cap Medicare for outpatient physical therapy services. However, Medicare continues to monitor therapy use with annual thresholds to ensure appropriate usage:
| Threshold | Amount (2025 estimated) | Requirement |
|---|---|---|
| KX Modifier | $2,410 (PT/SLP); $2,480 (OT) | Provider certifies ongoing medical necessity with detailed documentation |
| Medical Review Potential | $3,000 (PT/SLP & OT) | Targeted review by Medicare for improper payments; coverage continues if justified |
These thresholds apply across all outpatient therapy settings-doctor’s office, hospital outpatient departments, skilled nursing facilities (as an outpatient), rehabilitation clinics, and home health agencies (if you do not qualify for Part A home health coverage). The amounts are combined for physical therapy and speech-language pathology and reset each year.
After reaching $2,410 in combined physical therapy and speech-language pathology services, providers must use the “KX” modifier on billing claims to certify that therapy remains medically necessary. If your costs reach $3,000, Medicare may select your case for targeted review to ensure compliance and prevent improper payments. Despite these checks, there is still no cap on covered sessions as long as you meet documentation criteria.

Where Is Physical Therapy Covered Under Medicare?
The setting in which you receive physical therapy can affect your coverage, costs, and billing methods. Under Medicare, coverage is divided primarily into Part A (inpatient) and Part B (outpatient):
Outpatient Settings (Medicare Part B)
- Physician’s office
- Therapist’s private practice or group practice
- Hospital outpatient departments
- Independent outpatient rehabilitation facilities
- Skilled nursing facility (when receiving outpatient therapy but not meeting criteria for a Part A stay)
- Your home, if supplied by a Medicare-certified home health agency and you do not qualify for Part A home health care
Each setting must meet specific Medicare certification standards, and the providers must accept Medicare assignment for you to pay the lowest possible rate. If you require assistive devices for therapy-such as a hospital bed at home-see the guide How Do I Get a Hospital Bed from Medicare? for more on qualifying criteria and coverage details.
Inpatient Settings (Medicare Part A)
- Acute care hospitals
- Skilled nursing facilities (after a qualifying 3-day hospital stay)
- Inpatient rehabilitation hospitals or facilities
Coverage here is typically bundled with other Part A inpatient services during your hospital or facility stay.
Medicare Advantage and Supplement Coverage for Therapy
In addition to Original Medicare, many beneficiaries opt for a Medicare Advantage physical therapy plan (Part C) or a Medigap outpatient therapy policy for supplemental coverage. Each works differently:
Medicare Advantage (Part C)
These private insurance plans are required to offer at least the standard Medicare therapy benefits outlined by Parts A and B, but most add value with reduced copays, expanded provider networks, or additional benefits (such as fitness programs or certain telehealth options, though telehealth physical therapy is generally not covered by Original Medicare as of the latest update). Be sure to review each plan’s terms, as some may require referrals, prior authorization, or restrict you to network providers to access lower costs or extra services.
Medigap (Medicare Supplement)
Medigap policies, purchased from private insurers, help pay your share of therapy costs not covered by Original Medicare-primarily your 20% coinsurance and sometimes the Part B deductible. They do not expand the range of services covered but can significantly lower your out-of-pocket liability during extended or intensive therapy.

Key Considerations Before Starting Physical Therapy
- Doctor Referral & Written Plan: Obtain a detailed care plan and signed referral from your physician, nurse practitioner, or physician assistant.
- Provider Participation: Confirm your therapist accepts Medicare assignment to avoid balance billing or unexpected costs.
- Advance Beneficiary Notice (ABN): If your provider believes a service may not be covered, you should receive an Advance Beneficiary Notice ABN explaining your financial responsibility if you choose to proceed.
- Cost Tracking: Keep track of your expenses as you approach the therapy thresholds ($2,410/$3,000 in 2025). Discuss out-of-pocket costs with your provider and assess the value of supplemental coverage options.
- Settings Matter: Recognize that facility type affects both how therapy is billed to Medicare and your cost-sharing responsibility (hospital outpatient vs. therapist office vs. home health agency).
- Telehealth Physical Therapy: Virtual PT is not included in standard Medicare outpatient coverage, though some Medicare Advantage plans may offer it as an enhancement.
- Personal Data Updates: Make sure your contact and address details are current to avoid claim delays. For how to update these, reference How to Change Address with Social Security and Medicare.
