CMS Just Proposed Sunsetting Traditional MIPS: Here's Everything ACOs and MIPS Clinicians Need to Know About the CY2027 Rule

CMS proposes sunsetting traditional MIPS after 2028, making MVPs mandatory by 2029. New double-rate ACO modifiers (32% vs. 16%) reward ACO participation directly. MSSP benchmarking shifts to favor BASIC tracks, prior authorization eases in 2027 but doubles in 2028, and improvement activities gain a wellness focus. This is the biggest value-based care shakeup since MACRA began.
