Most insurers require prior authorization for GLP-1 weight-loss drugs. Approval typically needs BMI documentation, comorbidities (hypertension, sleep apnea), failed diet attempts, and sometimes step therapy (metformin first). Denials are common — appeals work.
Prior auth checklist
- BMI ≥30, or ≥27 with comorbidity (plan-specific)
- 6–12 months documented weight management attempts
- Recent labs (A1C, lipids) if diabetes indicated
- Prescriber letter of medical necessity
- BMI requirements by plan
How long prior auth takes
3–14 business days typical. Start before your current supply runs out. If denied, see appeal guide.
Cost while waiting
