Top 25 ACOs by gross savings
The Patient Protection and Affordable Care Act (ACA) created accountable care organizations (ACOs) to accomplish two goals: 1) deliver high-quality, coordinated care to specific patient bases and 2) reduce unnecessary expenses—while enabling ACOs to share in those savings via reimbursement through the Medicare Shared Savings Program.
An ACO’s gross savings/losses is a calculation of its total benchmark expenditures minus total aligned beneficiary expenditures. This metric shows the total amount saved or lost by the organization and represents the total savings (or losses) to be split between the ACO and the Centers for Medicare and Medicaid (CMS).
Check out our list of the top 25 ACOs in the U.S. according to their gross generated savings/losses below.
