Medicaid Drug Rebate Program & Medicaid Drug Program File Formats, Data Definitions, and Communications

Medicaid Drug Rebate Program (MDRP) file formats are used by CMS, states, and manufacturers to transmit and receive various data required by the MDRP. CMS is currently building a new Medicaid Drug Program (MDP) system in which all the current MDRP file formats will be transitioned to MDP file formats on July 1, 2021.

Throughout 2020, CMS sent out several state and manufacturer emails introducing the updated MDP file formats. To ensure that all recipients receive this information, we are posting the current MDRP file formats, as well as the updated MDP MDRP file formats and state and manufacturer email communication to Medicaid.gov.
