Eligible commercially insured patients may pay as little as $0 per month, with an annual limit of $18,000. See www.eisaireimbursement.com/patient/halaven for complete eligibility requirements and terms and conditions.

The EAP can help you

  • Understand how your therapy may be covered by your insurance
  • Understand your out-of-pocket cost, which is the part you pay for and can include co-pays, co-insurance, or deductibles
  • Identify sources of potential coverage if you do not have insurance, including eligibility for the Eisai Patient Assistance Program (PAP)

Eisai cannot guarantee payment of any claim. Coding, coverage, and reimbursement may vary significantly by payor, plan and setting of care. Actual coverage and reimbursement decisions are made by individual payors following the receipt of claims.
