Just over half of accountable care organizations (ACOs) said they would consider leaving the Medicare Shared Savings Program (MSSP) if required to take on more downside risk, revealed a study published in Health Affairs.
Thirty-two percent of ACOs said they are extremely or very likely to leave, and 19 percent believe they are moderately likely to leave.
In 2018, there were more than 600 ACOs managing care for nearly 12 million Medicare beneficiaries, the researchers said.
The majority of Medicare ACOs participate in Track 1 of the Medicare Shared Savings Program under a one-sided arrangement, also known as an upside-only structure. About 25 percent of Medicare ACOs were in two-sided or downside risk arrangements in 2018, including MSSP Track 1+, Tack 2, Track 3, and next generation ACOs.
