CMS made a profit from the Medicare Shared Savings Program last year as more accountable care organizations (ACOs) moved to risk-based contracts and gained experience, new federal data show. About 60 percent of the 472 Medicare ACOs generated a total of $1.1 billion in savings in 2017, according to the CMS data set released Thursday. CMS paid $780 million in bonuses to the ACOs, but the agency still scored a $313.7 million gain from the program. The announcement of substantial savings comes just weeks after CMS proposed overhauling the program, claiming it wasn't generating enough savings.
