In April 2015, Congress established a new framework for Medicare Part B physician payments through the passage of the Medicare Access and CHIP Reauthorization Act of 2015 (“MACRA”), which the Centers for Medicare & Medicaid Services ("CMS") has implemented through the Quality Payment Program (“QPP”). MACRA allows Medicare Part B clinicians to take part in the QPP in one of two ways: through the Merit-Based Incentive Payment System or through Advanced Alternative Payment Models. The first performance period is currently underway for clinicians subject to the Medicare Part B physician payment reforms enacted under MACRA.
