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 be prepared to provide invoices during audits for all drug products billed to Medicaid.
Action Required
Immediately: Pharmacy billing staff must download and reference the updated alpha and numeric lists of pharmaceutical labelers with signed rebate agreements. 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 supplies, lancets, ostomy items) may be dispensed regardless of labeler rebate agreement status.
