CMS has developed a web page for information on the use of Medicaid data in the ACA Branded Prescription Drug Fee Program. By way of background, under the ACA, the Secretary of the Treasury determines the amount of the fee to be paid by each manufacturer according to the manufacturer’s share of branded prescription drug sales to specified government programs, including Medicaid. The CMS web page describes how CMS calculates Medicaid sales for reporting to the Treasury Department, and how manufacturers can dispute state utilization data prior to calculation of the sales fee, including tips for manufacturers to submit complete and responsive data in connection with a dispute.
