Medicare Advantage

GLP-1 coverage under Medicare Part D and Advantage plans

Medicare's federal statute excludes weight-loss-only drugs from Part D — but T2D, cardiovascular risk reduction, and OSA indications are covered. Here is the practical 2026 reality plus the workarounds.

Quick fact: Zepbound for moderate-to-severe OSA in adults with obesity (FDA approval Dec 2024) is the first weight-loss-class drug covered by Medicare Part D after the indication was added.

What Medicare DOES cover

Ozempic (semaglutide) for type 2 diabetes — covered under Part D with PA. Mounjaro (tirzepatide) for type 2 diabetes — covered. Zepbound for OSA in adults with obesity — covered as of late 2024 with PA documenting AHI severity. Wegovy for MACE risk reduction in patients with established CVD + obesity — covered as of 2024 after the SELECT trial label expansion.

What Medicare DOES NOT cover

Wegovy or Zepbound for weight management without a qualifying medical indication. The federal Part D statute (42 U.S.C. §1395w-102) explicitly excludes drugs "used for cosmetic purposes or weight loss." Active legislative attempts to amend this have not yet succeeded.

Workarounds

Document a qualifying comorbidity (T2D, established CVD, OSA) — that pivots the medication to a covered indication. Some Medicare Advantage plans include supplemental wellness benefits; check your specific plan SBC. Cash-pay with manufacturer savings card is the last-resort path; $499/mo Wegovy is achievable for many.

Common questions

Will Medicare cover Wegovy for weight loss in 2026?

Not for weight loss alone. The Part D federal statute excludes weight-management indications. However, Wegovy IS covered for cardiovascular risk reduction in adults with established CVD and obesity (FDA approval 2024 after SELECT trial). Document the cardiovascular indication to qualify.

Does Medicare cover Zepbound for sleep apnea?

Yes — as of late 2024, Zepbound is covered under Part D for moderate-to-severe OSA in adults with obesity. PA requires sleep-study documentation of AHI severity. This was the first weight-loss-class drug covered by Medicare.
