Specific requirements vary by your employer's plan. Check your Summary of Benefits or call member services to confirm.
Drugs typically on Medicare's preferred tier
These have the lowest copays. Non-preferred or excluded drugs cost significantly more.
Important note about Medicare
Federal law (Medicare Modernization Act of 2003) excludes drugs for weight loss from Part D coverage. Workaround: get the diabetes-indicated drug (Ozempic or Mounjaro) if you have a covered diagnosis.
What if Medicare denies your GLP-1?
- Request the denial letter in writing.It must list the specific criteria you didn't meet.
- Ask your prescriber to file a peer-to-peer appeal. Documenting BMI ≥30, comorbidities (sleep apnea, hypertension, prediabetes), and prior weight-loss attempts often reverses denials.
- If still denied, consider self-pay options: LillyDirect for Zepbound (from $349/mo), NovoCare savings card for Wegovy, or telehealth platforms like Hims, Ro, and Found ($199–$499/mo).
