Does Medicare Cover Zepbound?

Drug Coverage · Weight & Metabolic

Zepbound (tirzepatide) is used for chronic weight management (and obstructive sleep apnea).

Does Medicare cover Zepbound?

Usually not — Medicare generally does not cover drugs used for weight loss alone. By law, Part D generally excludes drugs used only for weight loss, so Zepbound for weight management is typically not covered. Coverage may be possible when it’s prescribed for a separately approved condition (for example, obstructive sleep apnea) — this area is evolving.

Which part of Medicare covers it?

If covered for an approved non-weight-loss use, it would be Part D. Weight-loss-only use is generally excluded.

Typical formulary tier

Not typically on a formulary for weight loss. Your exact tier — and copay — depend on the plan you choose, which is why matching the formulary to your medications matters.

Prior authorization & plan rules

When any coverage applies, expect prior authorization confirming an approved, non-weight-loss diagnosis.

If it isn’t covered (or costs too much)

Talk with your doctor about whether an approved diagnosis applies, ask the manufacturer about savings programs (note: many exclude people with government insurance), and consider covered alternatives.
