What the reviewers wrote

Excerpts from the independent reviewers’ published findings — the actual reasoning, quoted, not summarised.

Where the denial was overturned

Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: The patient requested authorization and coverage for Wegovy solution auto-injector.The U.S. Food and Drug Administration (FDA) has approved Wegovy for the treatment of patients with obesity or overweight with one or more related medical conditions. In the STEP 1 randomized controlled trial, 1961 patients with overweight or obesity but without diabetes were treated with either Wegovy or a placebo in addition to lifestyle intervention. The authors found that the mean weight loss was greater in the group treated with Wegovy than in the group treated with a placebo. The STEP 4 trial was a randomized, double-blind, 68-week phase 3 trial of weight maintenance with semaglutide (Wegovy) at 2.4 mg weekly.

Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: The patient requested authorization and coverage for the Zepbound solution auto-injector.The U.S. Food and Drug Administration (FDA) approves tirzepatide, under the brand name Zepbound, for weight management in patients who are overweight, defined as a BMI of 27 kg/m² or greater, with at least one weight-related comorbidity, or who are obese, defined as a BMI of 30 kg/m² or greater. In this case, the records document that the patient has a BMI of over 40 kg/m². The authors reported that treatment with tirzepatide led to substantial, sustained weight loss, with a mean percentage change in body weight at week 72 greater than 20% in subjects on the maximum dosage of 15 mg weekly.

Where the denial was upheld

Worth reading too — these show what an appeal has to overcome.
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for bariatric surgery with Orbera intragastric balloon (CPT 43999). The records provided for review document that this patient has Class III obesity with a body mass index (BMI) of 47.2 kg/m2. The provider has recommended the Orbera intragastric balloon, which is U.S. Food and Drug Administration (FDA) approved for the treatment of obesity in patients with a BMI of 30-40 kg/m2 (Courcoulas, et al.; Vyas, et al.). The Orbera intragastric balloon lacks data supporting its use in patients with a BMI over 40 kg/m2. In addition, the guidelines from the American College of Cardiology (ACC), American Heart Association (AHA), and the Obesity Society do not recommend intragastric balloon therapy for long-term obesity therapy (Jensen, et al.).
