The Interoperability and Patient Access final rule (CMS-9115-F) includes policies that require states to exchange Buy-In and MMA files with CMS daily. Increasing these file exchanges will improve the experience of dually eligible individuals by helping states, providers, and payers improve the coordination of eligibility, enrollment, and benefits for this population. States are required to implement MMA and Buy-In daily exchanges with CMS starting April 1, 2022.
