100 ACOs to know | 2016

Becker's Hospital Review is pleased to highlight a variety of Medicare and commercial payer accountable care organizations, led by hospitals and health systems, physician groups and other organizations.

ACOs cover approximately 28.3 million lives, according to January 2016 data from Leavitt Partners. As value-based care matures, it has become clear that not all ACOs are created equal. CMS data from 2014 shows just one in four ACOs qualified for shared savings and several have left Medicare programs. Other research suggests growing pains are on the horizon. One study published in Health Affairs found physicians who participate in ACOs are more likely to practice in affluent areas — meaning value-based care has yet to touch some of the most vulnerable patient populations.

But for now, ACOs are still experiencing relatively unbridled growth. In January, an additional 100 organizations joined the ranks of MSSP ACOs and 21 were selected to join CMS' newest model, the Next Generation. Overall, Leavitt Partners estimates three-fourths of early Medicare ACO adopters are continuing in at least one of the Medicare programs. On top of that, hospitals and health systems continue to ink value-based care agreements with commercial payers, which account for approximately 60 percent of lives covered by ACOs, according to Leavitt Partners.

This is the fifth year Becker's Hospital Review has published its list of ACOs to know. ACOs were selected for inclusion based on a number of factors, including quality and cost performance, participation in CMS' Next Generation Model, the Pioneer Model, advanced tracks of the Medicare Shared Savings Program and if it has recently struck new commercial agreements. ACOs are presented in alphabetical order and are either listed by formal name of the ACO or, if the organization has several contracts, by name of the health system or provider group associated with those ACOs.

Note: ACOs are presented in alphabetical order and cannot pay for inclusion.
