When the Medicare Part D drug benefit was created, Congress excluded several categories of drugs by statute — and "agents when used for weight loss" is one of them. That exclusion still stands in 2026. So even though Wegovy is FDA-approved and widely prescribed, a Part D plan generally cannot pay for it when the reason is weight management. This is a legal rule, not a medical-necessity judgment — which is why it applies across nearly every plan regardless of your doctor's documentation.
In 2024 the FDA approved Wegovy to reduce the risk of cardiovascular events (heart attack, stroke) in adults with known heart disease who are overweight or obese. Because that's not "weight loss," Medicare Part D can cover Wegovy for that specific indication — and that's largely what the small percentage of plans listing it are covering. If you have established cardiovascular disease, it's worth asking your plan and prescriber whether you qualify under that indication.
It comes down to the approved use, not the molecule. Ozempic (semaglutide — the same active ingredient as Wegovy) is approved for type 2 diabetes and is covered on roughly 99% of Part D plans. Mounjaro (tirzepatide, for diabetes) is similar. Their weight-loss-branded twins — Wegovy and Zepbound — are the ones that hit the statutory exclusion. See the Ozempic breakdown →

Look up a drug — freeOnly if the law changes. Proposals to let Medicare cover anti-obesity medications have been discussed but, as of 2026, the statutory exclusion for weight-loss drugs remains in place. Coverage today is limited to other approved uses like cardiovascular risk reduction.
It can. Following the 2024 FDA approval for cardiovascular risk reduction, some Part D plans cover Wegovy for that indication — typically on a high specialty tier with prior authorization. Ask your plan whether you qualify based on your cardiovascular history.
The list price runs well over $1,000 per month. If your plan won't cover it, ask your prescriber about manufacturer savings programs (often limited for people on Medicare), or whether a covered alternative fits your situation.
Yes — for type 2 diabetes, Ozempic is on roughly 99% of Part D plans, usually Tier 3 with prior authorization. More on Ozempic coverage →
