What Highmark's policy requires for dental — medical necessity, oral surgery, tmj, cleft palate

Cited policy: BCBS plan-specific dental + Anthem clinical guideline (Orthognathic) + state cleft palate mandates

Highly state-specific. FEP BlueDental has separate riders. State mandates override (cleft, TMJ).

How Highmark denies dental — medical necessity, oral surgery, tmj, cleft palate — and how to counter it

Where Highmark pushes back: 1) Adult orthodontia cosmetic for cleft; 2) Cleft repair denied as 'dental not medical'; 3) FEP BlueDental cap exceeded.

Counter-arguments that hold up: Identify specific BCBS subsidiary policy. State cleft palate mandate (CA H&S §1367.68; NY/TX/FL/IL variants) — health insurer must cover medically necessary cleft care including orthodontia + implants. ACPA standards. Q35-Q37 ICD-10. FEP: cite OPM brochure + 5 CFR 890.105.
