How to appeal a Highmark atopic dermatitis (ad / eczema) 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 atopic dermatitis (ad / eczema)

Cited policy: BCBS Ebglyss (Lebrikizumab) for AD PA

Age >=12 yr and >=40 kg per Sep 2024 label. Moderate-severe AD. Failure of topical therapy. Step-therapy through Dupixent typical; contraindication or AE accepted. Reauth 16 wk EASI-75 or IGA 0/1.

How Highmark denies atopic dermatitis (ad / eczema) — and how to counter it

Where Highmark pushes back: 1) Try Dupixent or Adbry first; 2) Insufficient evidence vs older biologics.

Counter-arguments that hold up: Ebglyss IL-13 high-affinity binding (distinct epitope from Adbry / Dupixent IL-4Rα). FDA Sep 13, 2024 ages 12+ supported by ADvocate-1 + ADvocate-2 (Silverberg NEJM 2023 — EASI-75 ~58% vs ~16% placebo at 16 wk monotherapy), ADhere (with TCS), ADore (12-17). AAD 2024 + ETFAD/EADV 2024 list IL-13 selective biologics as parallel options. Class switching after Dupixent AE (conjunctivitis, facial dermatitis) or partial response is rational.

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.
