Bariatric surgery denied by insurance — how to appeal

About Bariatric surgery

Bariatric surgery denials are typically based on the patient not meeting the plan's specific criteria — most often a documented medically-supervised weight-loss program of 6+ months, BMI thresholds (often 40 alone or 35+ with co-morbidities), and psychological clearance. The appeal supplies any missing pieces and frames the case under the plan's own criteria.

Common reasons Bariatric surgery gets denied

  • BMI threshold not met under plan rules
  • Required medically-supervised weight-loss program not documented
  • Plan excludes bariatric surgery
  • Co-morbidity documentation insufficient

Evidence that helps overturn a Bariatric surgery denial

  • BMI history
  • Medically-supervised weight-loss program documentation (typically 6+ months)
  • Co-morbidity documentation
  • Psych evaluation if required
  • ASMBS / Endocrine Society guideline citation
