Medicare Part D appeal guide

Medicare Part D Wegovy coverage appeal

Medicare Part D uses specific clinical-policy criteria for Wegovy. Most denials come from undocumented BMI history or missing step-therapy notes. Here is how to address both.

Medicare Part D prior authorization criteria for Wegovy

  • Anti-obesity use EXCLUDED by federal law (Social Security Act §1860D-2(e)(2)(A))
  • Diabetes use COVERED if Ozempic/Mounjaro/Rybelsus prescribed for T2D
  • Cardiovascular risk reduction with semaglutide (Wegovy, FDA-approved Mar 2024 for CV indication) is increasingly covered

Step-by-step appeal flow

  1. 1

    Pull your carrier policy bulletin

    Medicare Part D publishes its Wegovy coverage criteria. Read it first — every successful appeal cites it back to the reviewer.

  2. 2

    Document your medical necessity

    Anti-obesity use EXCLUDED by federal law (Social Security Act §1860D-2(e)(2)(A)) Diabetes use COVERED if Ozempic/Mounjaro/Rybelsus prescribed for T2D Cardiovascular risk reduction with semaglutide (Wegovy, FDA-approved Mar 2024 for CV indication) is increasingly covered

  3. 3

    Have your prescriber submit the PA

    Most Medicare Part D 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

    For Wegovy/Zepbound (weight-only): cannot appeal — federal law excludes. For Wegovy CV-risk indication: appeal citing FDA-approved cardiovascular indication + patient meets SELECT 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

How much does Wegovy cost without insurance?
List price runs ~$1,350/mo at retail. NovoCare Pharmacy cash-pay direct from Novo Nordisk is $499/mo for all dose strengths. The Wegovy Savings Offer caps copay at $0-$225/mo for commercially insured patients depending on coverage status (not a flat $225 for everyone).
Full evidence-graded answer
Is Ozempic the same as Wegovy?
Same active molecule (semaglutide), different FDA indications and maximum doses. Ozempic = type 2 diabetes, max 2 mg/week. Wegovy = chronic weight management, max 2.4 mg/week. Insurance pathways are very different.
Full evidence-graded answer
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.
Full evidence-graded answer
How does Wegovy compare to Saxenda?
Both are GLP-1 agonists from Novo Nordisk. Wegovy (semaglutide, weekly) produces ~15% mean weight loss; Saxenda (liraglutide, daily) produces ~6-8%. Wegovy is also cheaper per kg-lost, more convenient, and has cardiovascular outcome data (SELECT trial). Saxenda was first approved for adolescents (2020); Wegovy followed in 2022 — both are available for ages 12-17.
