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

Cited policy: Anthem clinical guideline Bariatric Surgery (and BCBS medical policy Endoscopic Procedures for Obesity — typically labels ESG/balloon investigational)

Mostly mirrors NIH 1991 + ASMBS 2022 for surgical procedures (RYGB, sleeve, BPD/DS); endoscopic procedures (ESG, balloon, TORe) typically labeled investigational despite FDA clearance.

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

Where Independence Blue Cross pushes back: 1) ESG / balloon / TORe deemed 'investigational'; 2) BMI / supervised program; 3) Plan-level exclusion of bariatric.

Counter-arguments that hold up: For ESG cite MERIT trial (Abu Dayyeh Lancet 2022) — RCT supporting ESG vs lifestyle in BMI 30-40; FDA-cleared via Apollo OverStitch; ASMBS / ASGE 2022 Position. For intragastric balloon cite FDA approvals (Orbera 2015, ReShape 2015, Spatz 2021, Allurion 2023) and ASMBS / ASGE position. For TORe cite TWIN trial. Distinguish FDA-cleared from experimental — these are commercially available, FDA-cleared interventions.
