Short answer
It depends on the drug and why it is prescribed.
The Congressional Research Service says Medicare Part D does not cover GLP-1 drugs when used for weight loss, because of a long-standing statutory exclusion. It says Part D does cover them for medically accepted indications, such as type 2 diabetes, cardiovascular risk reduction, and obstructive sleep apnea. Separately, CMS says a new short-term demonstration called the Medicare GLP-1 Bridge will give eligible Part D beneficiaries access to certain weight-management GLP-1 drugs from July 1, 2026 through December 31, 2027, for a flat monthly copay processed outside Part D.

Plain answers first. Sources stay below for checking details.
For weight loss alone?
The CRS says Part D excludes GLP-1 drugs used only for weight loss.
For type 2 diabetes?
The CRS says Part D covers them for diabetes (Ozempic, Mounjaro, Rybelsus).
For heart or sleep-apnea reasons?
Covered: Wegovy for cardiovascular risk, Zepbound for sleep apnea.
Is there a new program?
Yes. CMS says the GLP-1 Bridge runs July 2026 to December 2027.

Bridge copay
Flat monthly

The real question is not whether Medicare covers GLP-1 drugs, but which drug, for which diagnosis, through which pathway.
Neutral landscape
The shape of the question
The Congressional Research Service is the main source for the rules because it summarizes the statutory weight-loss exclusion and the covered medical indications.
Source trail: Congressional Research Service
The covered uses come next, since the CRS says Part D covers GLP-1 drugs for type 2 diabetes and cardiovascular risk reduction.
Source trail: Congressional Research Service
The new pathway is the Bridge, which CMS describes as a short-term demonstration for certain weight-management GLP-1 drugs.
Source trail: CMS
The diagnosis routing matters because the CMS Bridge form sends diabetes, cardiovascular, sleep-apnea, and MASH cases to the Part D plan.

The forks people face
Most retirement questions hide a few smaller decisions. These are the practical pieces that change the plan.
What is the diagnosis behind the prescription?
Why it matters: A medical indication like diabetes is covered by Part D; weight loss alone is not.
In real life: This fork decides which pathway applies.
What to look at: What to look at: the CRS summary of covered indications.
Which drug is it?
Why it matters: Each brand has its own approved uses, so the brand changes the answer.
In real life: This fork narrows it to the exact drug.
What to look at: What to look at: the brand-specific coverage pages.
Are you looking at the Bridge?
Why it matters: The Bridge is a separate, time-limited pathway for certain weight-management drugs.
In real life: This fork is the new July 2026 option.
What to look at: What to look at: the CMS GLP-1 Bridge page.

How this page is curated
This page uses the Congressional Research Service summary of Medicare GLP-1 coverage, the CMS GLP-1 Bridge page and prior authorization form, the CMS BALANCE Model page, and the CMS drug-price-negotiation announcement. It separates the weight-loss exclusion, the covered medical indications, and the new Bridge because each is governed differently.
