GLP-1 Insurance & Prior Authorization: A Step-by-Step Guide

If your insurance might cover a GLP-1, it's worth fighting for — coverage can drop your cost from hundreds a month to a copay. The gatekeeper is usually a prior authorization (PA). Here's how to get through it.

Step 1: Find out if your plan covers it at all

Call the number on your insurance card and ask:

• "Is [Wegovy / Zepbound] on my formulary for weight management?"
• "Is a prior authorization required?"
• "What are the coverage criteria?" (e.g., BMI threshold, documented conditions)
• "What's my copay if approved?"

Many plans cover GLP-1 for obesity when BMI ≥ 30 (or ≥ 27 with a related condition like high blood pressure or type 2 diabetes). Criteria vary widely.

Step 2: Get your documentation ready

Your prescriber typically needs to submit:

• Your BMI and weight history
• Relevant diagnoses / comorbidities
• Records of prior weight-loss attempts (diet, programs, other meds) if your plan requires "step therapy"

The more complete the chart, the smoother the PA.

Step 3: Submit and follow up

Your clinic submits the PA to the insurer. Then:

• Ask for a reference number.
• Follow up in a few business days — PAs stall when no one chases them.

Step 4: If you're denied

A denial isn't the end:

1. Ask for the specific denial reason in writing.
2. File an appeal — your prescriber can submit a letter of medical necessity.
3. Check manufacturer savings cards to lower cost in the meantime.
4. Compare cash-pay options — in 2026 these dropped a lot ($150 oral pill, ~$350 direct-to-consumer).

A good clinic handles the paperwork

The PA grind is exactly what a strong telehealth clinic manages for you — some advertise a "prior-auth concierge." On TrimSoMo you can find clinics that take insurance and help with PAs. Browse clinics that accept insurance →
