Cigna Occupational Therapy Denied? How to Appeal Successfully

Occupational therapy helps people perform the essential activities of daily life after illness, injury, or disability. When Cigna denies OT coverage — whether for a stroke survivor relearning to dress and cook, a post-surgical patient rebuilding hand function, or a child developing sensory processing skills — the denial affects independence and safety. Cigna's Clinical Policy Bulletin 0325 governs these decisions, and when paired with the right clinical evidence and legal arguments, most occupational therapy denials can be successfully overturned.

Why Insurers Deny Occupational Therapy Claims

Cigna denies occupational therapy under several recurring rationales, all governed by Clinical Policy Bulletin (CPB) 0325, publicly available at cigna.com/healthcare-professionals.

"Maximum functional improvement reached": Cigna reviewers apply this when therapy appears to have plateaued. This denial ignores the Jimmo standard — the 2013 settlement in Jimmo v. Sebelius established that skilled care is covered when needed to maintain function or prevent deterioration, even without measurable improvement. Cigna's CPB 0325 explicitly includes maintenance therapy when skilled care is required, but reviewers frequently ignore this provision.

"Skilled care not required": This argument fails when the OT's clinical record documents the specific professional judgments and assessments made at each visit — standardized ADL assessments, treatment plan modifications, expert technique instruction. A visit involving clinical reasoning and expert guidance constitutes skilled care, not custodial service.

"Visit limit exceeded": For ACA essential health benefit plans, habilitative OT services are a required benefit under 42 USC 300gg-26. Challenge visit cap denials on EHB grounds for pediatric and habilitative claims. Applying a hard cap to habilitative therapy may violate the ACA's essential health benefits requirement.

"Home program sufficient": Counter with documentation of why the clinical complexity of the patient's needs requires ongoing skilled assessment — specifically what professional judgments does the OT make that a caregiver at home cannot perform?

How to Appeal

Step 1: Request CPB 0325 and Identify the Specific Criterion Cited

Obtain Cigna's Clinical Policy Bulletin 0325 and compare your clinical documentation against every criterion. Identify exactly which threshold Cigna claims you fail to meet before building your appeal arguments.

Step 2: Obtain Standardized ADL Functional Scores

Document baseline and current scores using recognized instruments: FIM (Functional Independence Measure), Barthel Index, AMPS (Assessment of Motor and Process Skills), or COPM (Canadian Occupational Performance Measure). FIM scores below 6 on any item, or Barthel scores below 60, directly demonstrate significant functional dependence supporting continued skilled OT.

Step 3: Get an OT Letter of Medical Necessity

Your OT should write a detailed letter addressing each CPB 0325 criterion: current functional deficits, specific clinical goals tied to activities of daily living, why skilled OT is required, and clinical consequences of discontinuing care. For maintenance therapy, the letter must document the specific skilled assessments the OT provides that a caregiver cannot perform.

Step 4: File Level 1 Internal Appeal Within 180 Days

Include CPB 0325, the relevant AOTA Clinical Practice Guideline for your diagnosis, current and baseline ADL scores, and your OT's letter of medical necessity. Reference Jimmo v. Sebelius explicitly if Cigna cited the improvement standard.

Step 5: Request Peer-to-Peer Review

Your OT or referring physician can request a direct conversation with Cigna's medical reviewer. Peer-to-peer review is particularly effective for OT denials because the clinical specifics — what skilled assessments occur at each visit — are best communicated in a clinical conversation.

Step 6: Pursue External Independent Review: Complete Guide" class="auto-link">External Review and File a State Complaint if Needed

Request a reviewer with OT specialty expertise. If visit caps violate ACA essential health benefit requirements, file a concurrent complaint with your state insurance department.

What to Include in Your Appeal

• CPB 0325 from cigna.com/healthcare-professionals, with the specific criterion at issue highlighted
