Medicare Shared Savings Program

Click to learn more about the NPRM Analysis!Background
The Medicare Shared Savings Program (MSSP) is the primary Medicare ACO program. The MSSP was derived from the Physician Group Demonstration Project, which started during the George W. Bush administration, and the MSSP was permanently authorized by the Patient Protection and Affordable Care Act. The MSSP began in 2012 with two participation options, Track 1 and 2. MSSP Track 3 was added in 2016 and the newest addition is Track 1+, which is detailed on this webpage. Track 1 has no downside risk and ACOs can only participate in Track 1 for a limited number of years. Tracks 1+, 2 and 3 all require certain levels of downside risk but have other benefits such as greater amounts of shared savings rewards and waivers from certain Medicare rules.
