How to appeal a Cigna bariatric surgery — rygb, sleeve, duodenal switch, sadi-s, revision, esg 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.

Cigna-specific note: Sold its Medicaid Advantage book to HCSC in 2023. Express Scripts (PBM) is Cigna-owned. Frequent class-action litigation around mental health parity.

What Cigna's policy requires for bariatric surgery — rygb, sleeve, duodenal switch, sadi-s, revision, esg

Cited policy: Cigna coverage policy Obesity Surgery (Initial and Revisional)

Initial: BMI thresholds + supervised program + multi-D eval. Revisional: documented complication of prior bariatric (refractory GERD with erosive esophagitis post-sleeve, mechanical complication, severe nutritional complication, inadequate weight loss / weight regain with comorbidity persistence).

How Cigna denies bariatric surgery — rygb, sleeve, duodenal switch, sadi-s, revision, esg — and how to counter it

Where Cigna pushes back: 1) Revision rationale 'inadequate weight loss' considered insufficient without comorbidity; 2) GERD documentation not severe enough (no LA grade C/D); 3) Time interval from prior surgery; 4) SADI-S / BPD revision pathway labeled experimental.

Counter-arguments that hold up: For sleeve→RYGB cite ASMBS Revisional Bariatric Surgery Position. Document EGD with LA grade, DeMeester / pH study, manometry; UGI showing dilated sleeve; weight regain percentage of EWL; comorbidity recrudescence (HbA1c rebound, BP rise, weight-related disability). Cite SLEEVEPASS 10-yr (Salminen JAMA 2022) for sleeve durability data. For SADI conversion cite ASMBS 2023 SADI-S Position.
