Prior authorization is a coverage review, not a prescription by itself
A GLP-1 prior authorization asks the health plan to review whether a branded medication fits its coverage rules. The plan may ask for diagnosis, BMI, weight-related conditions, A1C history, previous therapy, contraindications, or chart notes. That coverage step is different from the clinician deciding whether semaglutide or tirzepatide is medically appropriate for the patient.
- Wegovy and Zepbound are labeled for chronic weight-management uses; Zepbound also has an obesity-related obstructive sleep apnea indication. Ozempic and Mounjaro are labeled for type 2 diabetes care, not general cosmetic weight loss.
- Insurance plans can cover, deny, require step therapy, exclude weight-loss drugs, or ask for more records even when a clinician would consider treatment reasonable.
- Compounded semaglutide or tirzepatide discussions should be kept separate from branded FDA-approved product coverage; compounded finished products are not FDA-approved.
