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.

  3. Continued obesity despite trials of weight loss through lifestyle changes, diet modification and exercise evidenced by all of the following:

    • Documentation of active participation in a non-surgical weight reduction program supervised by a registered dietician, healthcare provider (e.g., physician, nurse practitioner), or an organized weight reduction program (e.g., Weight Watchers™, Jenny Craig™), for at least six consecutive months occurring within the last 18 months prior to the request for bariatric surgery
    • Monthly documentation of all of the following weight reduction program components:

      • Physical exercise unless medically contraindicated
      • Behavior modification or behavioral health interventions

    A Note About Weight Reduction Programs

    A physician’s summary letter is not sufficient documentation of active patient participation in a non-surgical weight reduction program. Documentation must include medical records and/or diet or weight-loss logs, and assessment of the patient’s progress throughout the programs course.

  4. Bariatric surgical consultation and recommendation by a trained and experienced bariatric surgeon associated with an institution that supports a comprehensive bariatric surgery program, which includes all of the following:
    • Psychological evaluation and clearance for bariatric surgery
    • Nutritional evaluation
    • Long-term monitoring and follow-up post surgery

Adolescents Requirements

  • BMI > 40.0 with at least one significant obesity-related disease complication which has failed to be controlled with medical management including, but not limited to:
    • Type 2 Diabetes Mellitus
    • Hypertension
    • Heart disease
    • Obstructive Sleep Apnea
    • BMI >/= 50.0 kg/m2 with less severe obesity-related complications

Revision Requirements

  • Revision surgery is considered medically necessary to address perioperative or late complications of a bariatric procedure. These include, but are not limited to:
    • Staple-line failure
    • Obstruction
    • Stricture Non-absorption resulting in hypoglycemia or malnutrition
    • Weight loss of 20% or more below ideal body weight
  • Revision of a primary bariatric procedure that has failed due to dilation of the gastric pouch (documented by upper gastrointestinal examination or endoscopy) is considered medically necessary when all of the following are met:
    • The initial procedure was successful in inducing weight loss prior to pouch dilation
    • The patient has been compliant with a prescribed nutrition and exercise program
    • The patient still meets BMI criteria for bariatric surgery

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.
