According to The Remington Report, more than half of the U.S. population lives in areas served by accountable care organizations (ACOs). Currently, 52 percent of U.S. patients live in primary care service areas served by ACOs. In August 2012, just 45 percent of the population lived ACO areas.
Additionally, at least 28 percent of U.S. patients live in areas served by two or more ACOs, up from 17 percent in August. All together, ACOs now cover 37 million to 43 million Medicare and non-Medicare patients. The expansion of coverage comes after CMS’ announcement of 106 new participants in the Medicare Shared Savings Program. There are now 259 Medicare ACOs.
