Frequently asked questions
Is Humira covered by Medicare?
No, in most cases. All 8 Medicare Administrative Contractors list Humira (J0139) as a self-administered drug, so Part B does not pay for it. It is usually covered under Part D instead. Check your MAC's self-administered drug list before billing.
What diagnoses are covered for Humira (J0139)?
Medicare publishes no drug-specific covered-diagnosis list for J0139. The 22 ICD-10 codes here are the FDA-approved indications; an off-label use needs approved-compendium support (DrugDex, NCCN) to be payable.
Which Medicare policy covers Humira?
Each Medicare Administrative Contractor's self-administered drug (SAD) exclusion article decides whether Part B pays: excluded from part b as self-administered (all 8 macs). No drug-specific LCD or Billing & Coding Article exists for Humira.
Why was my Humira claim denied as not medically necessary?
The most common cause is a diagnosis the MAC doesn't consider medically necessary for J0139. Bill a covered/FDA-approved indication from the list below, document medical necessity, and confirm any local guidance with your MAC.
