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 be prepared to provide invoices on audit, but non-drug items like needles, syringes, and diabetic supplies can be dispensed regardless of labeler rebate agreements.
Action Required
Immediately: Pharmacy staff must download and review the updated alpha and numeric lists of pharmaceutical labelers with signed rebate agreements. Ensure all pharmacy claims use accurate 11-digit NDC numbers. Maintain invoices for all drug products billed to Medicaid for audit purposes, regardless of acquisition source.
