What documentation do I need for GLP-1 prior authorization?

Typical prior authorization documentation for GLP-1 medications includes: current BMI calculation, documentation of obesity-related comorbidities (sleep apnea, hypertension, type 2 diabetes, etc.), proof of participation in supervised weight management programs, lab work showing metabolic markers, and sometimes documentation of failed attempts with other weight loss treatments. Your provider must complete the insurer's specific prior authorization form.

Additional documentation may include medication history, previous weight loss attempts with lifestyle interventions or other medications, and letters of medical necessity explaining why the specific GLP-1 is appropriate for your case. Some insurers require ongoing documentation for continued coverage, including regular weight checks and lab monitoring. Having complete documentation upfront can reduce denial rates and speed up approval.
