Practical note
Ask why the answer was no
Was the product excluded, the diagnosis not covered, the paperwork incomplete, or a different product preferred? The next question depends on which answer the plan gives.
Coverage sheet
Coverage follows the reason for treatment
A plan may pay for an ingredient under one diagnosis and refuse it under another. “Is the drug covered?” is only half the question.
Rules checked: September 2026.
For private insurance
Ask your insurance plan about the exact brand, injection or tablet, and the reason written on the prescription. Then ask whether the plan must approve it before you fill it (called prior authorization), what records it needs, and which pharmacy it prefers. A benefit summary may not show those details.
For Medicare
As of September 2026, federal law still excludes a medicine from the basic Medicare drug benefit when it is used for weight loss.
Medicare may cover that very drug if the prescription is written for a different accepted purpose, type 2 diabetes for example, but the plan’s own list of covered drugs (its formulary) and its approve-first rules still apply.
Separately, Medicare is running a temporary trial program. From July 2026 through December 2027, people who qualify and have Medicare drug coverage are charged $50 monthly for selected GLP-1 weight-loss drugs, in injection or tablet form.
Ask your Medicare drug plan whether you qualify before you pay full price.
