How Much Physical Therapy Will Medicare Pay For?
How Medicare Covers Physical Therapy Under Part B
Medicare Part B offers extensive coverage for medically necessary outpatient physical therapy (PT) services. Unlike earlier years, there is no strict Medicare physical therapy limit in terms of session numbers per year. As long as your therapy is prescribed by your physician or a qualified health care provider, and meets Medicare’s criteria for medical necessity, you can continue receiving outpatient PT. Covered locations include doctor’s offices, clinics, outpatient hospital departments, skilled nursing facilities (under outpatient rules), and even your home-if you do not also qualify for standard home health benefits.
Under Part B, after you satisfy the annual deductible-set at $257 in 2025-Medicare pays 80% of the Medicare-approved amount for outpatient therapy. You are responsible for the remaining 20%, known as Medicare coinsurance. This cost-sharing applies regardless of where you receive therapy. If you have a Medigap plan, such as those discussed in Medicare Supplement Plans in Mississippi for 2026, some or all of your out-of-pocket payments may be covered.
Physical Therapy in Other Medicare Parts
When therapy is provided as part of an inpatient hospital stay (Medicare Part A), costs and rules change. Coverage generally includes $0 copays for the first 60 days, then daily copays starting at day 61. For skilled nursing facilities, PT is bundled with other rehab services for qualified stays.
What Happened to the Medicare Therapy Cap?
The longstanding Medicare therapy cap on outpatient services ended in 2018 with the Bipartisan Budget Act. Previously, beneficiaries were restricted to an annual dollar limit for PT and related therapies before coverage stopped. This cap, often referred to as the Medicare therapy cap, created barriers to care for many patients requiring extensive rehabilitation.
Now, Medicare uses an annual therapy threshold (sometimes called the Medicare therapy cap threshold) to monitor high utilization. If you exceed the monetary threshold for outpatient PT and speech-language pathology (SLP) services combined or occupational therapy (OT), your care can continue-but stricter documentation rules apply. This modernized approach better aligns coverage with medical necessity.
Annual Therapy Thresholds: 2024, 2025, 2026 Updates
Rather than limiting the number of sessions, Medicare reviews the total cost of therapy each year using set thresholds, which increase according to the Medicare Economic Index (MEI). Exceeding the therapy threshold triggers specific reporting and documentation requirements-but it does not mean your coverage ends if care remains medically necessary.
| Year | PT/SLP Combined Threshold | OT Threshold | Notes |
|---|---|---|---|
| 2024 | $2,330 | $2,330 | Annual update |
| 2025 | ~$2,410 | ~$2,410 | Increase based on MEI |
| 2026 | $2,480 | $2,480 | KX modifier required beyond this threshold |
The KX modifier is essential for claims that surpass the threshold-for example, when your combined PT/SLP visits cost more than $2,480 in 2026. This signals to Medicare that your therapy continues to be medically required. Notably, the Targeted Medical Review (TMR) threshold-set at $3,000 until 2028-may prompt additional claim review and documentation requests for especially high-cost cases, but therapy itself does not automatically cease at that point.
Understanding the KX Modifier and Medical Necessity
The KX modifier is critical for ongoing Medicare coverage beyond the annual PT or OT spending limit. When total billed charges for outpatient PT and SLP services (or OT) exceed the current year’s threshold, providers must append this modifier to each subsequent claim. In doing so, they are attesting that the care being provided continues to meet medical necessity requirements for diagnosis or treatment according to Medicare’s standards.
Medical necessity is defined as care that is reasonable and required to treat a specific illness, injury, disease, or symptom-and it includes certain types of skilled maintenance therapy aimed at slowing functional decline (such as degenerative neurological conditions).
- 8-Minute Rule: For accurate billing, Medicare uses the “8-minute rule.” Providers can report 1 unit of timed therapeutic services (e.g., manual therapy, exercise) for every 8 minutes performed. Untimed codes-such as supervised modalities-are billed separately.
- Medicare Physical Therapy Documentation: After passing therapy thresholds, documentation intensifies. Every visit must reflect ongoing assessment, progress, and justification for continued care to support claim payment and compliance if reviewed.
If a service goes beyond what Medicare covers or is not considered medically necessary, the provider may offer an Advance Beneficiary Notice (ABN) and bill the claim with a GA modifier. This allows you to decide whether to proceed and pay privately should Medicare deny the claim.
When Does Medicare Trigger a Targeted Medical Review?
Once your billed charges for PT/SLP or OT services reach the separate $3,000 Targeted Medical Review (TMR) threshold, Medicare may flag your claims for extra scrutiny. Providers could be asked to submit detailed records supporting the necessity, complexity, and duration of your therapy, especially if your case is atypically complex, prolonged, or costly.
This review process does not automatically interrupt or end your care. If your documentation is thorough and demonstrates need, coverage continues without interruption. Therapy providers, especially those experienced with Medicare billing, proactively monitor all patients approaching or surpassing these review triggers.
Beneficiaries can help by keeping open channels with their providers and being aware of their progressing therapy costs and utilization. For further guidance on how these rules intersect with broader Medicare coverage, review related benefits, such as those detailed in How Often Will Medicare Pay for a Hospital Bed?.
What Will I Pay for Physical Therapy With Medicare?
Most outpatient PT services are covered at 80% of Medicare’s approved amount, leaving you responsible for 20% coinsurance after your Part B deductible. For 2025, the deductible is scheduled to be $257. Your actual out-of-pocket cost per session typically falls in the $50-$100 range, depending on geography and provider contracts.
- If your provider is not enrolled in Medicare, or you receive services not considered medically necessary, you may have to pay full price.
- An appropriate Medicare Supplement (Medigap) plan may cover all or some of your coinsurance obligations.

It’s important to verify whether your provider participates in Medicare and to request cost estimates in advance, especially if approaching or exceeding therapy thresholds.
Exceptions, Requirements, and Important Modifiers
Continued therapy above the threshold is supportable only with documentation of medical necessity. This is strictly required for Medicare payment, and ambiguous records can prompt claim denials or audits. For example, Medicare does not cover non-skilled services such as gym memberships or general fitness training. Only therapy aimed at restoring or maintaining function, or treating a diagnosed condition under a professional plan of care, qualifies.
- GA Modifier: If your therapist believes Medicare may deny a service, your Advance Beneficiary Notice (ABN) outlines potential non-coverage-and the GA modifier accompanies your claim indicating you have been notified and agree to be responsible for costs if Medicare denies payment.
- Medicare does not cover non-professional, purely supportive services like massages or exercises not tied to a specific plan of care.
- Providers should adhere to the documentation requirements substantiating every visit, including goals, progress, and outcomes.
Original Medicare vs. Medicare Advantage Coverage
| Aspect | Original Medicare (A/B) | Medicare Advantage (Part C) |
|---|---|---|
| PT Coverage | 80% after deductible; no session cap with KX modifier. | At minimum, matches A/B. May include gym, wellness, or expanded rehab. Check plan specifics for costs or session caps. |
| Out-of-Pocket Costs | 20% coinsurance after deductible. | Copays may be lower or structured differently. Plans include out-of-pocket max protections. |
| Provider Choice | Any Medicare-certified provider. | Plan network restrictions often apply. |
Medicare Advantage (Part C) plans must provide, at the least, the same outpatient PT benefits as Original Medicare, but may offer additional features or cost differences. Many plans offer gym memberships, wellness visits, or enhanced rehabilitation options but may restrict access to in-network providers or place administrative limits on therapy utilization. If considering switching or disenrolling, review How Do I Disenroll from Medicare Advantage Plan in 2026? for important enrollment period rules and steps.
Key Takeaways: Staying Informed on Medicare Physical Therapy Limits
- There is no hard Medicare physical therapy limit on session numbers. Annual dollar thresholds (the “therapy cap”) now simply trigger modifier and documentation requirements.
- For 2024, 2025, and 2026, expect outpatient therapy thresholds of $2,330, ~$2,410, and $2,480, respectively. Surpassing these limits requires the use of the KX modifier and strong ongoing documentation of medical necessity.
- The Targeted Medical Review threshold is $3,000-claims above this may be audited but are not automatically denied.
- Medicare covers 80% of approved outpatient therapy charges; you owe 20% plus any deductible, unless you have supplemental coverage (e.g., Medigap).
- Stay proactive-confirm your provider participates in Medicare, and monitor your therapy costs as you approach annual thresholds.
- Coverage, deductibles, coinsurance, and documentation practices update yearly. Rules and amounts may differ for those with higher income or additional Medicare taxes, so verify with Medicare.gov or your insurer for personalized information.
By understanding annual updates, the role of the KX modifier, and your cost-sharing obligations, you can ensure ongoing access to the Medicare-covered therapy you need without unnecessary denial or interruption.
