Leavitt Partners is out with new numbers on the growth and distribution of accountable care organizations in the past year. The firm reports there were 221 ACOs identified through May 2012. Sponsoring organization headquarters were hospital systems in 118 of the ACOs, physician groups in 70, insurers for 29, and community-based groups for 4. However, ACOs can vary multiple ways in structure. Leavitt Partners has classified ACOs into 4 categories with the percentage each currently represents of the total:
- Single-provider [usually an integrated delivery system]: 67%
- Multiple-provider [such as a hospital and physician organization partnership]: 19%
- Insurer: 8%
- Insurer-provider [equal partnership]: 6%
There are ACOs in 45 states, but most are concentrated in urban areas. The Deep South and Appalachia continue to see only limited ACO development compared to other regions.
The report does not list the 221 individual ACOs identified.
