Coverage Requirements


  • 35+ Body Mass Index (BMI)
  • Documentation of failed diet attempts
  • Psychological evaluation


Even if your insurance company covers bariatric surgery in some plans, that does not mean that your specific plan covers it. The obesity surgery approval requirements in this section assume that weight loss surgery is covered by your specific policy.

To confirm whether your specific policy covers bariatric surgery, click here to contact a surgeon and ask for a free insurance check.

  4. Documentation from the requesting surgical program that:
    • Documentation from the surgeon attesting that the patient has been educated in and understands the post-operative regimen, which should include ALL of the following components:
      1. Nutrition program, which may include a very low calorie diet or a recognized commercial diet-based weight loss program
      2. Behavior modification or behavioral health interventions
      3. Counseling and instruction on exercise and increased physical activity
      4. Ongoing support for lifestyle changes to make and maintain appropriate choices that will reduce health risk factors and improve overall health
    • Patient has completed an evaluation by a masters level or higher behavioral healthcare provider acting within the scope of their licensure under applicable state law, within the 12 months preceding the request for surgery. This evaluation should document:
      1. The absence of significant psychopathology that would hinder the ability of an individual to understand the procedure and comply with medical/surgical recommendations
      2. The absence of any psychological comorbidity that could contribute to weight mismanagement or a diagnosed eating disorder
      3. The patient’s willingness to comply with preoperative and postoperative treatment plans

Some of the Reasons for Denial

Even if you meet the 2 requirements outlined in this section, you will likely NOT be approved if any of the following apply to you:

  • Patients with mental handicaps that render a patient unable to understand the rules of eating and exercise and therefore make them unable to participate effectively in the post-operative treatment program (e.g., a patient with malignant hyperphagia [Prader-Willi syndrome], which combines mental retardation/intellectual disability with an uncontrollable desire for food)
  • Patients with portal hypertension, an excessive hazard with laparoscopic gastric surgery
  • Women who are pregnant or lactating
  • Patients with serious medical illness in whom caloric restriction could exacerbate the illness

Revision Requirements

Repeat/Revision of bariatric surgery: may be considered medically necessary (when specifically included as a benefit or covered service in the member’s benefit plan, summary plan description or contract) only when ALL of the following criteria are met:

  • Original surgery was considered a covered benefit of the member’s current plan, AND the repeat/revision of bariatric surgery is a covered benefit of the member’s current plan
  • For the original procedure, patient met all the screening criteria, including BMI requirements
  • The patient has been compliant with a prescribed nutrition and exercise program following the original surgery
  • Significant complications or technical failure (e.g., breakdown of gastric pouch, slippage, breakage or erosion of gastric band, bowel obstruction, staple line failure, etc.) of the bariatric surgery has occurred that requires take down or revision of the original procedure that could only be addressed surgically
  • Patient is requesting reinstitution of an acceptable bariatric surgical modality
  • NOTE: A Roux-en-Y procedure following a previously approved vertical banded gastroplasty or laparoscopic adjustable banded gastroplasty is not eligible for coverage for patients who have been substantially noncompliant with a prescribed nutrition and exercise program following the original procedure

If Your Policy Does NOT Cover It: Seek Partial Coverage

You may be able to get part of the costs paid for by insurance even if weight loss surgery isn’t covered. It’s all about how your doctor and hospital submit your claims to your insurance company.

For example, there are many non-bariatric surgery reasons for your doctor to recommend:

  • Cardiology exam
  • Lab work
  • Medically supervised diet program
  • Psychological exam
  • Sleep study

These are ordered for many reasons other than bariatric surgery and may be covered as a result. If your doctor submits one of these claims using a weight loss surgery CPT code (Current Procedural Terminology Code), your insurance is unlikely to cover it. But if your doctor uses a general CPT code, it probably will be covered.

While this may sound “sneaky”, it is an ethical practice. After all, these tests will be beneficial regardless of whether you move forward with surgery.
