MACRA replaced the SGR with a 0.5 percent annual rate increase through 2019 and a +/- 4 percent payment adjustment, based on 2017 performance. MIPS combines the Physician Quality Reporting System (PQRS), the  Value-based Payment Modifier, and  Meaningful Use into a single program.
Under MIPS, physicians will be paid based on success in four performance categories: quality, cost, improvement activities, and advancing care information through use of health information technology. The advancing care criteria is based on the government’s meaningful use program, which is used to decide whether doctors should be rewarded for using electronic health record technology. Medicare reimbursement for providers in 2019 will be based on how well doctors perform on metrics this year.
