How to appeal a Highmark pediatric therapy denial

The framework that applies to your appeal

Federal law gives you the right to a full and fair internal appeal, then an external review by an independent third party.

Highmark-specific note: Operates BCBS in PA (western), WV, DE, NY (western). Owns Allegheny Health Network.

What Highmark's policy requires for pediatric therapy

Cited policy: Anthem Clinical UM Guideline clinical guideline (ABA) / clinical guideline (Speech) / clinical guideline (OT/PT)

Hard visit caps on speech/OT/PT (e.g., 20-30 visits/yr combined); 'No further functional gains expected' standard.

How Highmark denies pediatric therapy — and how to counter it

Where Highmark pushes back: 1) Hard visit caps; 2) 'No further functional gains expected'; 3) Dual-therapy denials.

Counter-arguments that hold up: Habilitative EHB argument — pediatric habilitation is NOT rehabilitation; visit caps designed for adult rehab are inappropriate. APTA Pediatric and AOTA peds practice guidelines endorse longitudinal care for developmental conditions. State mandate; EPSDT for Medicaid.

How to submit the appeal to Highmark

1. Read the denial letter — note the exact denial reason code and the appeal deadline (180 days from the date on the letter).
2. Gather supporting documentation: physician letter of medical necessity, relevant clinical notes, peer-reviewed citations supporting the treatment for your indication, and the policy or coverage document Highmark cited in the denial.
3. File the appeal through Highmark's portal (members: https://www.highmark.com ; providers: https://www.highmark.com/provider). Standard decision returns within 30 days; expedited urgent appeals return within 72 hours.
4. If denied again, request external review by an independent reviewer within 4 months of the final internal denial. In PA, the state insurance department coordinates external review for fully-insured plans; ERISA self-funded plans use a federal external review through DOL/EBSA.
