There were 428 total accountable care organizations in the US as of January 10, 2013, according to Leavitt Partners’ Center for Accountable Care Intelligence. Every state but Delaware had at least one ACO. This count includes both Medicare and private ACOs.
The Center also reports that physician group-led ACOs increased the most over the past year and are now more numerous, though generally smaller, than hospital-run ACOs. Insurers or community-based groups sponsor some ACOs as well, but there are fewer of them.
While Medicare ACOs have similar structures, the private ACOs have a wider range of payment models – full or partial capitation, bundled payments, retainer agreements, in-kind services and subsidies, and pay-for-performance incentives.
