Quarterly Average Manufacturer Price (AMP) Data for Drugs in the Medicaid Drug Rebate Program: Reported or Not Reported
In accordance with the terms of the National Drug Rebate Agreement and section 1927(b)(3)(A) of the Social Security Act (the Act), drug manufacturers participating in the MDRP are required to report AMP information to the Centers for Medicare & Medicaid Services (CMS) each quarter. A quarterly AMP must be reported for each active drug that the manufacturer has reported for inclusion in the MDRP. Failure to submit the required AMP data may result in penalties, such as the drug manufacturer’s termination from the rebate program or the issuance of civil monetary penalties by the Office of the Inspector General.
In an effort to improve the timeliness of the data CMS receives from drug manufacturers each quarter, CMS is posting the quarterly AMP reported or not reported file. This file contains the active drugs that have been submitted as of the most recent reporting period under the MDRP, along with an indication of whether or not the required AMP was reported for each drug. All drugs are identified in the file by the 11-digit NDC, product name, labeler name, and reported (R) or not reported (NR). Please note that, due to confidentiality provisions found in section 1927(b)(3)(D) of the Act, this file does not contain actual AMP values; rather, it simply notes whether or not CMS received an AMP for each drug included in the file. Further, the file only reflects AMP data that was received at the time that Medicaid drug rebates were calculated for the most recent reporting period. Finally, the only terminated drugs included in this file are those that are being terminated within the quarter represented in the file, or those with a termination date in the future.
