How do I appeal a Wegovy insurance denial?

Most commercial insurance Wegovy denials are reversible with a well-documented appeal. First, request the specific denial reason in writing — common reasons include missing prior auth, BMI not documented, no comorbidity recorded, or step-therapy requirement (try another drug first). Your prescriber then submits a letter of medical necessity addressing the denial reason directly. The letter should include: documented BMI with date measured, list of weight-related comorbidities with diagnosis codes, prior weight-management attempts (lifestyle modification, prior medications, prior surgical evaluation if applicable), and a statement of medical necessity. Commercial-plan internal appeal turnaround is typically 30 days; expedited appeals (for urgent medical need) are 72 hours. If the internal appeal fails, you can pursue external review through your state's insurance department. Run NovoCare self-pay in parallel while waiting — appeals can take weeks and you don't want to interrupt treatment.
