Summary
The Illinois Department of Healthcare and Family Services has updated the lists of pharmaceutical labelers with signed Medicaid Drug Rebate Agreements. Pharmacies must use accurate 11-digit NDC numbers when billing and be able to produce invoices on audit for all drug products billed to the department.
Action Required
Immediately: Pharmacy staff must download and reference the updated alpha and numeric lists of pharmaceutical labelers with signed rebate agreements from the Illinois HFS website. Ensure all drug claims use accurate 11-digit NDC numbers and maintain invoices for all drug products billed to Medicaid for audit purposes. Non-drug items (needles, syringes, diabetic supplies) can be dispensed regardless of labeler rebate agreement status.
