Insurance pre-check
Quick heuristic estimate. Not a guarantee — final approval is at your insurer's discretion based on your specific plan and prior-auth review.
Approval is plan-dependent. Some plans within this carrier cover; others don't. Verify with your specific plan's formulary or call the number on your insurance card before assuming.
Aetna's Wegovy policy (4774-C) approves adults with a baseline BMI of 30 or more, or 27 or more with a weight-related condition, after at least 6 months in a comprehensive weight management program. The first approval lasts 7 months. Whether your plan includes weight-loss drugs at all depends on your plan.

BMI is one screening tool. It doesn't measure muscle vs fat, and clinicians use additional criteria for GLP-1 eligibility.
BMI ≥ 27 is a common screening threshold for GLP-1 programs (with a comorbidity). Final eligibility is up to a clinician.
