Step-by-step appeal flow

  1. 1

    Pull your carrier policy bulletin

    Express Scripts (PBM) publishes its Mounjaro coverage criteria. Read it first — every successful appeal cites it back to the reviewer.

  2. 2

    Document your medical necessity

    PA criteria set by sponsoring plan, not Express Scripts directly Standard: BMI ≥30 + lifestyle documentation

  3. 3

    Have your prescriber submit the PA

    Most Express Scripts (PBM) PAs go through CoverMyMeds or the carrier portal. Your prescriber attaches BMI history, comorbidities (with ICD-10 codes), lifestyle program participation, and prior weight-loss attempts.

  4. 4

    If denied — file the appeal within 60 days

    Express Scripts is the pharmacy benefit manager — the underlying plan's PA criteria apply. Check the plan's coverage document; Express Scripts processes the appeal but doesn't set the criteria.

  5. 5

    Submit external review if internal appeals fail

    After two internal appeals, you can request external review through your state insurance commissioner. ERISA plans go through the federal external-review process.

Common questions readers ask

Can I still get compounded GLP-1 in 2026?
For semaglutide: no — FDA declared the shortage resolved February 21, 2025 and 503A compounding is no longer broadly permitted. For tirzepatide: shortage resolved October 2024 (re-affirmed December 2024), with a wind-down enforcement window that ended in 2025. Some clinics still market "compounded" formulations with added ingredients (B12, glycine) as personalized prescriptions; the legal status is contested.

Why do GLP-1 medications cost so much in the US?
List prices ($1,100-$1,350/mo) reflect manufacturer pricing, US-specific lack of price negotiation (until IRA implementation), and high R&D recovery on patent. Cash and PAP programs now bring effective prices to $349-$499/mo (NovoCare Pharmacy, Lilly Direct).
