What is an ACO?

Founded in 2011 by the Centers for Medicare and Medicaid Services (CMS), ACOs, or accountable care organizations, are groups of healthcare providers that work together to care for certain patient populations. ACOs deliver coordinated care that helps healthcare providers—like hospitals and physicians—improve patient satisfaction, improve population health, and reduce per capita healthcare costs.

What is the Medicare Shared Savings Program?

The Medicare Shared Savings Program (MSSP) enables suppliers and healthcare providers to establish an ACO and deliver high-quality, efficient, affordable, and coordinated care to patient populations.

When did the Medicare Shared Savings Program start?

The Medicare Shared Savings Program (MSSP) program started in 2012, one year after ACOs were created. The MSSP initially started with two tracks, Track 1 and Track 2. In 2016, Track 3 was added, followed by Track 1+ in 2018. These tracks represent levels of participation that reflect the amount of risk an ACO takes on in caring for an assigned Medicare fee-for-service population.

Medicare Shared Savings Program results

As supported in our table above, many ACOs that participate in the MSSP are successful in saving earnings. Across the top 10 list, the ACOs collectively saved more than $350 million, with an average savings of $35,466,442 per ACO.
