Notes
These counts are based on certified Accountable Care Organization (ACO) Participant Lists and assignment methodology for each given performance year. Data are provided at the county level and aggregated to the state level. State ACO enrollment excludes ACO enrollment in counties where data was suppressed due to low enrollment counts (between 1 and 10 total assigned beneficiaries). Total counts do not include beneficiaries in U.S territories.
