How to appeal a Premera Blue Cross specialty biologics 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.

Premera Blue Cross-specific note: BCBS licensee for Washington and Alaska (~2.4M members). Express Scripts PBM. WA OIC oversight. WA has strong mental health parity enforcement and surprise-billing protections that pre-date federal NSA.

What Premera Blue Cross's policy requires for specialty biologics

Cited policy: Anthem/Elevance Clinical UM Guideline clinical guideline - Adalimumab and Biosimilars

Moderate-severe disease + conventional therapy failure + TB/Hep B/C screening. Most BCBS plans now require biosimilar adalimumab first (2024-2026 adoption wave).

How Premera Blue Cross denies specialty biologics — and how to counter it

Where Premera Blue Cross pushes back: 1) Drug non-formulary; 2) Step therapy: failure of two preferred TNFi biosimilars required; 3) Lab work older than 12 months; 4) Missing rheumatologist/dermatologist/gastroenterologist attestation.

Counter-arguments that hold up: Identify the specific BCBS subsidiary and cite its named policy by number — generic appeals are weaker. For BCBS FEP: governed by FEHB; appeals to OPM after internal exhaustion (5 CFR 890.105). State external review under NAIC Model Act timelines. For self-funded ERISA BCBS plans: demand full claim file under 29 CFR 2560.503-1(h)(2)(iii).
