Illinois has updated the lists of pharmaceutical companies with signed Medicaid drug rebate agreements. Pharmacies must use accurate 11-digit NDC numbers when billing and maintain invoices for audit purposes, while non-drug medical supplies can be dispensed regardless of rebate agreements.
Action Required
Immediately: Pharmacy staff must ensure all Medicaid drug claims use accurate 11-digit NDC numbers from the updated pharmaceutical labeler lists. Download and reference the current alpha and numeric lists from the Illinois Department of Healthcare and Family Services. Maintain invoices for all drug products billed to Medicaid for audit purposes. Non-drug items (needles, syringes, diabetic supplies, lancets, ostomy items) can be dispensed from any labeler regardless of rebate agreement status.
