Summary
The Illinois Department of Healthcare and Family Services has updated the lists of pharmaceutical labelers that have signed Medicaid Drug Rebate Agreements with CMS. Pharmacies must use accurate 11-digit NDC numbers when billing and be prepared to provide purchase invoices during audits.
Action Required
Immediately: Pharmacy staff must download and reference the updated alphabetic and numeric lists of pharmaceutical labelers with signed rebate agreements from the Illinois HFS website. Ensure all drug claims use accurate 11-digit NDC numbers. Maintain invoices for all drug products billed to Medicaid for audit purposes. Note that covered non-drug items (needles, syringes, diabetic testing supplies, lancets, ostomy items) can be dispensed regardless of rebate agreement status.
