Start with the plan’s own answer
Ask for the plan’s list of medicines it covers. That list is called a formulary. The plan may also have to approve payment before the prescription can be filled by the pharmacy. That step is called prior authorization.
Medicare’s usual prescription-drug plan may pay when a medicine treats a condition such as diabetes, rather than weight loss alone. The exact medicine must still meet your plan’s coverage and approval rules.

Medicare has a usual rule and a separate programme
As of September 2026, medicine solely for weight loss is not covered by the usual Medicare prescription-drug plan.
CMS · usual prescription rulesA separate temporary programme offers certain weight medicines to people who qualify, under terms checked in September 2026. Their share of the bill, called a copay, is $50 each month.
CMS · Medicare GLP-1 BridgeThat programme begins in July 2026, with December 2027 as its closing month. The usual Medicare drug plan caps your spending on covered prescriptions each year. Money paid for the temporary programme does not bring you closer to that limit; it is an extra cost.
CMS · programme dates and payment termsThe government page sets out who qualifies. Ask the prescriber and plan which route applies to your situation.
A savings card has its own rules
As checked in September 2026, the branded GLP-1 savings cards for prescription copays require private health insurance. Those cards cannot be used by people covered through Medicare, Medicaid or a military plan.
Dated price record · savings-card termsPeople with government coverage can use some medicine-maker cash offers by paying the price themselves. A cash offer has its own rules, separate from the savings card.
