MGMA joined the American Medical Association and more than 100 physician specialty and state medical organizations in a letter urging Congress to ensure smooth implementation of Medicare payment policies under the Medicare Access and CHIP Reauthorization Act (MACRA). In particular, MGMA and the medical community call for a three-year extension of program flexibility to ensure physician practices are able to successfully participate in the new Merit-Based Incentive Payment System (MIPS) while CMS finalizes cost measures, improves data feedback, and provides tools to improve performance. Among other refinements, the letter requested clarification that Medicare Part B drugs are outside the scope of MIPS payment adjustments.
