MEDICARE DRUG BENEFITThe base rule
As of September 2026, the Medicare drug benefit still excluded medicines when they were used only for weight loss.
As of September 2026, Mounjaro for type 2 diabetes or Zepbound for sleep apnea could be eligible for ordinary Medicare drug coverage, but each plan could still apply its own list and review rules.

As of September 2026, a temporary Medicare program called the Medicare GLP-1 Bridge offered certain weight medicines for $50 a month through December 31, 2027.
It is for people with a Medicare drug plan who qualify. Ask your drug plan whether you do.

Ask the clinic which of the three it plans to prescribe.
