Why physical therapy denials happen so often
Physical therapy (PT) is one of the most frequently denied outpatient services in commercial and Medicare insurance, not because the underlying value is contested but because payers routinely reduce coverage by capping visits, requiring re-authorization every few visits, or terminating coverage when the patient stops showing measurable functional improvement. If your PT was approved at 8 or 12 visits and then cut off because 'no further benefit is expected,' or if your plan has a hard annual visit cap that doesn't match what your physical therapist documented as medically necessary, the denial is almost always appealable. The legal framework actually favors the patient: the Medicare Benefit Policy Manual (Pub. 100-02), Chapter 15 explicitly recognizes maintenance therapy as a covered Medicare benefit following the Jimmo v. Sebelius settlement (D. Vt. 2013), and the ACA's essential-health-benefit rules require commercial plans to cover habilitative and rehabilitative services. The challenge is producing the documentation that meets the payer's specific 'medically necessary' criteria for continuation.
Why PT gets denied
Visit cap reached - the plan's annual or per-condition visit limit has been hit
Lack of measurable functional progress - 'no further benefit is expected' is the most common Medicare denial language
Maintenance therapy denied as 'custodial' (despite Jimmo v. Sebelius settlement clarifying maintenance is covered)
Documentation does not include objective functional outcome measures (e.g. Berg Balance Scale, Oswestry, FIM scores)
Treatment plan not signed by the physician within the certification window (Medicare requires plan certification within 30 days)
Use of unskilled modalities (hot packs, ultrasound alone) without skilled intervention documented
Concurrent or duplicate billing with occupational therapy without separate skilled rationale
PT delivered in the home without home-health certification
Federal and state protections for PT
Under the Affordable Care Act, rehabilitative and habilitative services are essential health benefits that non-grandfathered individual and small-group plans must cover (45 CFR section 156.115). For Medicare Part B outpatient therapy, the prior 'therapy cap' was eliminated by the Bipartisan Budget Act of 2018; what remains is a 'targeted medical review' threshold ($2,410 in calendar year 2025 for combined PT and SLP services, separate amount for OT) that triggers extra review but not automatic denial. The Jimmo v. Sebelius settlement (Civil No. 5:11-cv-17, D. Vt. Jan. 24, 2013) prohibits Medicare from denying skilled therapy on the sole basis that the beneficiary has 'plateaued' or is not improving - maintenance and prevention of decline are covered when skilled care is required to perform them safely. ERISA plans must provide a full and fair review of any visit-cap or medical-necessity termination under 29 CFR section 2560.503-1.
Evidence checklist for your appeal
- Physical therapist's plan of care signed and dated by the certifying physician within the past 30 days
- Objective functional outcome measures from initial evaluation, midpoint, and most recent re-assessment (FOTO, Oswestry, DASH, Berg Balance, TUG times)
- Daily treatment notes documenting skilled intervention - hands-on manual therapy, neuromuscular re-education, gait training - not unskilled modalities alone
- Quote from the Jimmo v. Sebelius settlement if denial cites lack of progress or plateau
- Letter from the referring physician confirming continued medical necessity and risk of decline without continued skilled care
- Comparison of current functional status to documented goals showing remaining gap
- If the visit cap is the issue: the plan's specific contract language and a citation to the ACA habilitative/rehabilitative essential health benefit if applicable

Insurer-specific patterns and tactics
UnitedHealthcare commonly delegates PT prior authorization and concurrent review to Optum's musculoskeletal program, which applies tighter visit thresholds than the underlying plan. Anthem uses AIM Specialty Health (now Carelon) for advanced imaging and some musculoskeletal programs. Aetna's clinical policy bulletin 0325 (Physical Therapy) is the document to quote when contesting an Aetna PT denial. Cigna applies its own outpatient therapy clinical policy, frequently denying after 12-20 visits. For Medicare Advantage, the October 2024 Senate PSI report documented that PT and other post-acute services are denied at higher rates by MA plans than by traditional Medicare. Cite the report in MA appeals.
