Summary
The Centers for Medicare and Medicaid Services has updated the alphabetic and numeric 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 the rebate program applying only to drugs (not supplies like needles, syringes, or testing supplies).
Action Required
Immediately: Pharmacy staff must download and reference the updated alphabetic and numeric lists of pharmaceutical labelers from the Illinois Department of Healthcare and Family Services. Ensure all drug claims use accurate 11-digit NDC numbers and maintain purchase invoices for all billed drug products for audit purposes. Verify that only drugs from labelers with signed rebate agreements are billed to Medicaid.
