The Center for Medicare & Medicaid Services (CMS) announced that there will be 561 Accountable Care Organizations (ACO) in the Medicare Shared Savings program in 2018, an increase from 480 in 2017. The number of beneficiaries in these ACOs in 2018 is 10.5 million.
- Shared Savings ACOs receive a portion of any financial savings if they meet quality and cost benchmarks. Providers can also choose to share in losses in exchange for receiving a higher percentage of savings. For 2018, 101 ACOs have chosen these higher risk/reward payment tracks.
CMS also announced that 58 ACOs will participate in the Next Generation ACO model which gives participants the opportunity to take on even higher levels of financial risk, up to 100 percent. In exchange, Next Generation ACOs receive a greater share of potential savings.
The chart below outlines several ACO models, their main features, and the number of ACOs in each for 2018. For a list of all Shared Savings ACOs by state, go to the CMS page, "ACOs in Your State." It explains how to obtain detail on each organization.
