Is stelara covered by medicare part b?

Short answer: it depends on how Stelara (ustekinumab) is given.

- If Stelara is administered by a clinician in a medical setting (for example, an initial IV infusion or injections given in a doctor’s office or infusion center), Medicare Part B typically covers it.
- If you self-administer Stelara injections at home (maintenance doses after a clinician’s prescription, such as subcutaneous injections every 8 weeks), this is usually covered under Medicare Part D (your prescription drug plan), not Part B.

Coverage can vary by your specific plan (Part D plan details, whether you have a Medicare Advantage plan, etc.), so it’s best to confirm with:
- Your Medicare Part B plan or the plan’s beneficiary services
- The medical provider or infusion center billing for Stelara
- Medicare (1-800-MEDICARE) or Medicare Plan Finder for your exact coverage
- Your prescriber or pharmacy to see how they bill for your situation

If you want, tell me your plan type (Part B vs Part D, or Medicare Advantage) and how Stelara will be administered (clinic vs home self-injection), and I can help you interpret the likely coverage.
