Summary
The Illinois Department of Healthcare and Family Services 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.
Action Required
Immediately: Pharmacy billing teams 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 invoices for all drug products billed to Medicaid for audit purposes. Non-drug items like needles, syringes, and diabetic supplies can be dispensed regardless of labeler rebate agreements.
