Medicaid accountable care organizations (ACOs) are becoming increasingly prevalent in state Medicaid delivery systems. States see ACOs as an effective way to improve patient outcomes and control costs by shifting accountability for risk and quality to providers.

Since 2012, the Center for Health Care Strategies’ (CHCS) Medicaid ACO Learning Collaborative has assisted 16 states and the District of Columbia in developing and launching their Medicaid ACO programs through interactions with federal and state policymakers and subject matter experts, technical assistance, and discussion of common successes and challenges in developing these initiatives. To date, eight state participants have instituted Medicaid ACO programs, with more expected to launch programs in the near future.

The current phase of the collaborative, phase IV, builds on the successes of phases I – III to help additional states design and launch their own programs. CHCS is currently assisting Medicaid agencies from the District of Columbia, LouisianaMassachusettsMaryland, North CarolinaRhode Island, Virginia, and Washington in developing payment models, quality measurement strategies, and data and analytic capacity to put their Medicaid ACO programs into place. CHCS is also working with these states to help determine how these models can work in conjunction with a Medicaid managed care environment.

Resources generated from the collaborative will be shared broadly to inform other states looking to pursue their own Medicaid ACO models, and are posted below.
