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

The framework that applies to your appeal

Medicare Advantage plans follow a separate appeal track from commercial plans. Reconsideration must be requested within 60 days; if the plan misses its deadline, the case auto-forwards to the IRE (Maximus).

Humana-specific note: Heavily Medicare Advantage focused. MA-specific appeal track (42 CFR Part 422 Subpart M) applies — 60 days to request reconsideration, NOT the 180 days for commercial plans. Auto-forward to IRE (Maximus) if Humana misses deadline.

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

Cited policy: Humana Medicare Advantage — defers to CMS coverage and ASMBS / IFSO endorsement; SADI-S coverage variable

CMS NCD 100.1 covers RYGB, BPD/DS, sleeve, lap band at facilities meeting CMS conditions of coverage. SADI-S, OAGB historically not covered under NCD 100.1 — coverage variable by MAC.

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

Where Humana pushes back: 1) SADI-S / OAGB not under NCD 100.1; 2) Facility not at CMS-approved Center; 3) BMI / comorbidity threshold; 4) Supervised program documentation.

Counter-arguments that hold up: Cite ASMBS 2023 SADI-S Position Statement endorsing SADI-S as MBS option (SOARD 2023); IFSO 2018 BPD/DS endorsement. Document facility MBSAQIP accreditation (CMS recognized accreditation). For BMI cite ASMBS 2022 Indications (Eisenberg SOARD 2022). Document each NCD line-item where applicable. Coverage may also fall under part of Medicare Advantage plan addendum allowing extended bariatric procedures.
