Summary
Illinois updated the lists of pharmaceutical labelers with signed Medicaid Drug Rebate Agreements. Pharmacies must use accurate 11-digit NDC numbers when billing and be prepared to provide purchase invoices during audits, regardless of the drug source.
Action Required
Immediately: Pharmacy staff must verify they are using the updated alpha and numeric lists of pharmaceutical labelers with signed rebate agreements from CMS. Ensure all drug claims use accurate 11-digit NDC numbers. Maintain invoices for all drug products billed to Medicaid for audit purposes, regardless of acquisition source. Non-drug items (needles, syringes, diabetic supplies, lancets, ostomy items) can be dispensed from any labeler.
