Does Medicare Cover Dupixent?

Drug Coverage · Autoimmune & Skin

Dupixent (dupilumab) is used for eczema, asthma, and COPD.

Does Medicare cover Dupixent?

Yes — Part D covers Dupixent for approved conditions, with criteria. Covered for approved uses like moderate-to-severe eczema, certain asthma, and COPD. Self-injected, so it’s a Part D drug.

Which part of Medicare covers it?

Part D. These are self-administered prescriptions, so they fall under your Part D drug plan (or the drug coverage built into a Medicare Advantage plan), not Part B.

Typical formulary tier

Specialty tier (typically Tier 5). 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

Prior authorization is standard; plans usually require documentation of severity and prior treatments.

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

Your doctor can appeal; manufacturer and foundation programs assist many patients.
