Summary
The Illinois Department of Healthcare and Family Services has 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 drug acquisition source.
Action Required
Immediately: Pharmacy billing staff must download and review the updated alpha 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. Non-drug items (needles, syringes, diabetic testing supplies, lancets, ostomy items) may be dispensed regardless of labeler rebate agreement status.
