CMS provides state Medicaid agencies with multiple data exchanges and data sharing programs to support coordination and program operations for people who are dually eligible for Medicare and Medicaid. CMS’s five data sharing programs support the following datasets: Medicare Modernization Act (MMA) File Exchange, Buy-In File Exchange, Territory Beneficiary Query (TBQ) File, Enrollment Database (EDB) File, and the Medicare-Medicaid Data Sharing Program.
In 2019, CMS reviewed these data sharing programs and the accompanying agreements. As part of this review, CMS developed an agreement to streamline redundancies across all the agreements currently governing the data programs. CMS’s goal is to provide states with one agreement that covers all available data sharing programs.
