MACRA combines several existing quality programs into the new MIPS program or allows participation in Advanced APMs. MIPS has four performance categories (quality, advancing care information, improvement activities, and cost). In 2017, physicians will submit baseline data for these categories to determine 2019 payment adjustments. Physicians have options to fully participate, partially participate, or test MIPS requirements. Those in Advanced APMs may receive a 5% incentive payment. Over 50% of physicians are estimated to be exempt from MIPS requirements.
