In Nov. 2018, the Centers for Medicare & Medicaid Services (CMS) finalized changes to the Merit-based Incentive Payment System (MIPS) and Alternate Payment Models (APMs), which are generally effective on Jan. 1, 2019. This resource provides a quick overview of the differences between the 2018 and 2019 requirements. In response to MGMA recommendations, the third year of MIPS continues an on-ramp to participation and increases flexibility for medical groups. MGMA will continue to advocate on behalf medical groups by calling on CMS to improve the MIPS program.
