Summary
Illinois has updated the lists of pharmaceutical labelers with signed Medicaid Drug Rebate Agreements. Pharmacies must use accurate 11-digit NDC numbers when billing and maintain invoices for audit purposes, with rebate requirements applying only to drugs (not supplies like needles, syringes, or diabetic testing supplies).
Action Required
Immediately: Pharmacy staff must download the updated alpha and numeric lists of pharmaceutical labelers from the Illinois HFS website. Ensure all drug claims use accurate 11-digit NDC numbers and maintain purchase invoices for all drug products billed to Medicaid for audit purposes.
