The number of Accountable Care Organizations (ACO) in the Medicare program continues to grow, along with the number of beneficiaries who receive care from ACO providers.
- Shared Savings ACOs: In 2018, 561 ACOs will participate in the Medicare Shared Savings Program, an increase from 480 in 2017. The number of assigned beneficiaries in such ACOs will increase to 10.5 million, up from 9 million in 2017 and 7.7 million in 2016. Shared Savings ACOs receive a portion of any financial savings if they meet quality and cost benchmarks. Providers that choose to share in potential losses can qualify to receive a higher percentage of savings.
- Next Generation ACOs: In 2018, 58 ACOs will participate in Medicare’s Next Generation ACO model, an increase from 45 in 2017. This ACO model gives providers the opportunity to take higher levels of financial risk than Shared Savings, up to 100 percent. In exchange, Next Generation ACOs receive a greater share of potential savings. CMS has not yet reported the number of beneficiaries in these ACOs in 2018.
