Before You Start: Verify Your Coverage

Check Your Plan Type and Benefits

First, confirm whether Sylvant is covered under your medical benefit (Part B) or pharmacy benefit. Since Sylvant is administered by IV infusion, it's typically covered under the medical benefit and billed using HCPCS code J2860.

Call the member services number on your insurance card to verify:

  • Your current formulary tier for Sylvant
  • Whether step therapy requirements apply to your specific plan
  • Your in-network infusion center options
  • Your estimated out-of-pocket costs after prior authorization

Confirm Your Diagnosis Meets Coverage Criteria

UnitedHealthcare covers Sylvant specifically for patients with idiopathic multicentric Castleman disease (iMCD) who are:

  • HIV-negative (documented lab results required)
  • HHV-8-negative (documented lab results required)
  • Age 18 or older
  • Free from active clinically significant infections
