MACRA and the future of value-based care.

The passage of Medicare Access and Children's Health Insurance Program Reauthorization Act of 2015 (MACRA) heralded a fundamental shift from volume-based to value-based payment for health care services in the United States. Beginning in 2019, neurologists will participate in 1 of 2 Medicare pathways: the Merit-Based Incentive Payment System or Alternative Payment Models. Both options represent an important change from the current fee-for-service payment models, and neurologists will need to be prepared well in advance of the MACRA launch. This article reviews the background, structure, uncertainties, and implications of MACRA on the practice of neurology, with recommendations for preparation.
