OC Staff Am I Covered

Medicare covers weight loss surgery in most cases assuming you meet the coverage requirements. Not every weight loss procedure is covered either. If the criteria are met, Medicare covers Gastric Bypass, Lap Bands and Gastric Sleeve surgeries.

Medicare pre-approval requirements

The following criteria must be met in order for Medicare to cover your weight loss surgery:

  • BMI (body mass index) of 35 or greater – What’s your BMI?

    • i.e. sleep apnea, high blood pressure, diabetes, etc.
  • You must have documented evidence that you’ve been obese for the last 5 years.
  • Documented participation in a medically supervised weight loss program. Typically, you must show that you have participated and failed more than one program.
  • A letter from your physician recommending or supporting weight loss surgery.
  • Passed a psychological evaluation.
  • All other treatable medical diseases have been ruled out as a possible cause for your obesity. Adrenal, pituitary, or thyroid screening tests have been completed and are normal.
