Does Medicare Cover Humira?

Drug Coverage · Autoimmune & Skin

Humira (adalimumab) is used for rheumatoid arthritis, psoriasis, Crohn’s, and more.

Does Medicare cover Humira?

Yes — Part D covers Humira (and its biosimilars) for approved autoimmune conditions. Covered for approved diagnoses like rheumatoid arthritis, psoriatic arthritis, plaque psoriasis, and Crohn’s. Self-injected pens are Part D; biosimilars may be preferred.

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 for biologics, and plans often prefer a biosimilar first (step therapy).

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

If cost is high, biosimilars can be cheaper, and manufacturer/foundation grants help many people. Ask us to compare.
