Why occupational therapy denials happen so often
Occupational therapy (OT) helps patients regain or develop the ability to perform activities of daily living (ADLs) and instrumental ADLs - dressing, bathing, feeding, fine motor tasks, return to work, sensory processing, cognitive rehabilitation following stroke or traumatic brain injury, and pediatric developmental therapy. Like physical therapy, OT is regularly denied by commercial and Medicare payers either through a hard annual visit cap or through 'no further benefit' termination after a small number of visits. Pediatric OT is denied more often than adult OT because plans frequently exclude services they characterize as 'developmental' or 'educational' rather than 'medically necessary,' a line that the ACA's habilitative essential health benefit, the IDEA framework, and state autism mandates have all narrowed in recent years. The appeal strategy mirrors PT in its evidence requirements but differs in which clinical outcome measures are appropriate (Canadian Occupational Performance Measure, AMPS, FIM self-care subscores) and which clinical policies the payer is likely citing.
Why OT gets denied
Annual visit cap reached under the plan contract
No measurable functional improvement documented (similar to PT 'plateau' denials)
Service characterized as 'developmental' or 'educational' rather than medically necessary - common in pediatric OT
Sensory integration therapy denied as experimental or investigational by some plans
Plan of care not certified by physician within Medicare's 30-day window
Documentation lacks objective ADL or IADL outcome measures
Concurrent billing with PT denied without separate skilled rationale
Hand therapy denied as not requiring a Certified Hand Therapist (CHT) when the plan policy required one
Federal and state protections for OT
Occupational therapy receives the same essential-health-benefit protection as physical therapy under 45 CFR section 156.115 (rehabilitative and habilitative services). The Jimmo v. Sebelius settlement (D. Vt. 2013) applies to OT as well as PT and SLP - Medicare may not deny solely on lack-of-improvement grounds when skilled maintenance care is required. State autism-coverage mandates in over 45 states (e.g. New Jersey's autism benefit law, California Mental Health Parity Act extensions) often require OT for autism-related sensory or motor needs. The Mental Health Parity and Addiction Equity Act (MHPAEA, 29 USC section 1185a) limits non-quantitative treatment limitations - if your plan applies stricter visit caps to behavioral-health-adjacent OT than to medical/surgical OT, that is a parity violation and DOL has been actively enforcing.
Evidence checklist for your appeal
- OT plan of care with goals, frequency, and duration, signed by certifying physician within Medicare's 30-day window when applicable
- Objective outcome measures: Canadian Occupational Performance Measure (COPM), Assessment of Motor and Process Skills (AMPS), Sensory Profile, FIM self-care subscores
- Daily treatment notes documenting skilled intervention (not just protected play or supervised practice)
- For pediatric appeals: developmental milestones table comparing current function to age-appropriate norms
- Letter of medical necessity addressing why the OT is medically necessary, not educational or developmental support that schools should provide
- If sensory integration is denied as experimental: peer-reviewed literature (Schaaf et al., American Journal of Occupational Therapy)
- For autism-related OT: state autism mandate citation specific to your state

Insurer-specific patterns and tactics
UnitedHealthcare's Optum unit applies the same musculoskeletal review program to OT as it does to PT, with similar visit-frequency thresholds. Aetna Clinical Policy Bulletin 0250 covers occupational therapy and is the document to cite in Aetna appeals. Anthem and Blue Cross plans frequently route pediatric OT through behavioral health if the diagnosis includes autism, sensory processing disorder, or ADHD - which then triggers MHPAEA parity scrutiny. Cigna excludes 'sensory integration therapy' under specific circumstances; the appeal should distinguish skilled OT that uses sensory-based interventions from a pure SI program.
