Accountable Care Organizations (ACOs): Lessons from the Medicare Shared Savings Program
November 13, 2015


Sally Coberly, PhD


The Medicare Shared Savings Program (MSSP), enacted as part of the Patient Protection and Affordable Care Act of 2010, created financial incentives for health care providers to form accountable care organizations (ACOs) to better coordinate care for beneficiaries in traditional fee-for-service Medicare. The goal of the program is to improve quality and reduce costs. As of January 2015, over 400 MSSP ACOs were providing care to more than 7.3 million Medicare beneficiaries. Results have been mixed, with about one-quarter of ACOs performing well enough to share savings with Medicare. This Forum Session provided an overview of the program including recent changes, reviewed performance results to date, and looked in-depth at the experiences of three MSSP ACOs.
