Today’s announcement by the Center for Medicare & Medicaid Services on the 2020 performance of Medicare Shared Savings Program accountable care organizations is worthy of celebration. For the fourth consecutive year, the Medicare program realized net savings from MSSP, with this year totaling $1.9 billion. Through aligned incentives, MSSP ACOs were also winners, earning 2.3 billion in shared savings. Notably, these results occurred during a pandemic, showing how ACOs operate in a more resilient manner than fee-for-service medicine. The success of MSSP reflects its status as a permanent program that has been refined and improved over time; the program should serve as the foundation for advancing additional promising value transformation policies in the future. The Health Care Transformation Task Force applauds the ACOs whose commitment to MSSP has contributed to this impressive track record of success and advanced moving away from the antiquated fee-for-service system.
