How plans usually cover it
- Many employer plans exclude weight-loss medicines entirely, so check your formulary first.
- When covered, plans usually require prior authorization: a recorded BMI, weight-related conditions, and sometimes proof of a diet program.
- Renewals often require documented weight loss (commonly at least 5%) after the first 3 to 6 months.
- Medicare Part D can't cover drugs used only for weight loss under current law, but it can cover approved uses such as heart-risk reduction (Wegovy) or sleep apnea (Zepbound). Federal pricing and coverage announcements in late 2025 may have changed this for 2026; check Medicare.gov.
- Medicaid coverage for obesity varies by state.
