Does Medicare cover Zepbound or Wegovy?
Not for weight loss through a normal Part D drug plan, because federal law bars Medicare from covering weight-loss drugs. But from July 1, 2026 to December 31, 2027, Medicare’s GLP-1 Bridge covers Wegovy (semaglutide) and the Zepbound (tirzepatide) KwikPen for weight, at $50 a month, for people who meet its criteria.
- GLP‑1 medicines are prescription-only in the US. Coverage rules decide who pays, not whether a medicine suits you.
- Medicare rules here come from CMS, Medicare.gov and KFF, checked October 12, 2026. They are temporary and may change.
Why don’t Medicare drug plans cover weight-loss drugs?
KFF, a health-policy research group, says “Medicare has been prohibited by law from covering medications when used specifically for weight loss.”1
The rule comes from a list in federal law of drugs that “may be excluded from coverage”, which includes “agents when used for anorexia, weight loss, or weight gain”.2 Part D’s legal definition of a covered drug leaves out the drugs on that list.7
The ban applies to weight-loss use. Part D plans can cover GLP‑1s for type 2 diabetes, to lower heart risk, and for sleep apnea, says KFF.1 So a plan may cover Wegovy for someone with heart disease, or Zepbound for obstructive sleep apnea, under its usual rules.
What does the Medicare GLP-1 Bridge cover?
The Bridge is a temporary CMS program, from July 1, 2026 to December 31, 2027, with a $50 copay for a 28- or 30-day supply.3,4
It covers Foundayo tablets, Wegovy injection and tablets, and the Zepbound KwikPen only. CMS says “the single-dose Zepbound pen and Zepbound vials are NOT covered.”5
It runs outside Part D. The $50 doesn’t count toward your Part D deductible or the yearly out-of-pocket cap, $2,100 in 2026, and Extra Help (the Low-Income Subsidy) doesn’t apply to it.1 Who can use it is in Who qualifies for the Medicare GLP-1 Bridge?, and how prescriptions and coverage work is in Guide 6.
What if you have diabetes, sleep apnea or fatty liver disease?
Then the Bridge isn’t for you: CMS sends people with type 2 diabetes, moderate-to-severe sleep apnea or MASH to their own Part D plan instead.5
Your plan applies its own formulary and prior authorization rules. People who already get a GLP‑1 through their Part D plan can’t switch to the Bridge either.5
After 2027 the picture is unclear. CMS says its longer-term BALANCE Model will not launch in Part D in 2027.6 KFF says it is uncertain how people will keep Medicare coverage of these medicines for weight after the Bridge ends, pending further action from CMS.1 You can check your eligibility at Medicare.gov/glp1bridge or on 1-800-MEDICARE (1-800-633-4227).4
