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 maintain invoices for audit purposes, with reminders that non-drug items like needles and testing supplies are not subject to rebate agreement requirements.
Action Required
Immediately: Pharmacy staff must download the updated alpha and numeric lists of pharmaceutical labelers from the Illinois HFS website. Ensure all Medicaid drug claims use accurate 11-digit NDC numbers. Maintain invoices for all drug products billed to demonstrate purchase records for potential audits. Non-drug items (needles, syringes, diabetic supplies, lancets, ostomy items) may be dispensed regardless of labeler rebate agreement status.
