How to appeal an Aetna 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.

Aetna-specific note: Owned by CVS Health since 2018. CVS Caremark is the PBM. Aetna ASA administers self-funded ERISA plans. Meritain Health is Aetna's TPA brand.

What Aetna's policy requires for gerd & severe reflux

Cited policy: Aetna CPB on Branded PPI Step Therapy (Dexilant / Aciphex / Nexium Rx)

Trial of 2-3 generic PPIs at maximized doses x 4-8 weeks each. Documented intolerance or failure.

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

Where Aetna pushes back: 1) Generic available; 2) Insufficient generic PPI trial; 3) Duplicative therapy.

Counter-arguments that hold up: Dexilant dual delayed-release MR pharmacokinetics differ from generic. Document nocturnal acid breakthrough on pH study + intolerance (rash, headache, hyponatremia, C. diff). For shift-workers / erratic meal timing: dual-release advantage. Pregnancy: Cat B preferences for sucralfate or specific PPIs.

How to submit the appeal to Aetna

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 Aetna cited in the denial.
3. File the appeal through Aetna's portal (members: https://www.aetna.com ; providers: https://www.aetnaprovider.com). 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 CT, the state insurance department coordinates external review for fully-insured plans; ERISA self-funded plans use a federal external review through DOL/EBSA.
