How to appeal a Highmark gerd & severe reflux 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 gerd & severe reflux

Cited policy: BCBS Anti-Reflux Surgery — Nissen / Toupet Fundoplication

Objective GERD evidence (EGD erosive esophagitis >=LA-B OR pH-impedance abnormal off PPI). Failure / intolerance of medical therapy OR patient preference for surgical management with adequate response. Manometry to rule out achalasia / major motility disorder (avoid 360° Nissen in IEM — use Toupet instead).

How Highmark denies gerd & severe reflux — and how to counter it

Where Highmark pushes back: 1) More PPI trial required; 2) Patient is PPI-responder; 3) Manometry not done.

Counter-arguments that hold up: LOTUS JAMA 2011 + REFLUX UK BMJ 2008 — long-term surgical superiority for objective GERD with hiatal hernia. Spechler NEJM 1992 — surgery effective even in PPI-responders. Anatomic hiatal hernia is mechanical, not pharmacologic, problem. Submit DeMeester >14.72, EGD with hiatal hernia, manometry showing normal/IEM motility (Toupet for IEM).

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.
