Summary
Updated lists of pharmaceutical labelers with signed Medicaid Drug Rebate Agreements have been released by CMS. Pharmacies must use accurate 11-digit NDC numbers when billing and maintain invoices for audit purposes, with rebate requirements applying only to drugs (not medical supplies like needles, syringes, or diabetic testing supplies).
Action Required
Immediately: Pharmacy staff must download and reference the updated alpha and numeric lists of pharmaceutical labelers with signed rebate agreements from the policy notice. Ensure all drug claims use accurate 11-digit NDC numbers and maintain purchase invoices for all drug products billed to Medicaid for audit purposes. Non-drug items (needles, syringes, diabetic supplies, lancets, ostomy items) can be dispensed regardless of labeler rebate agreement status.
