Accountable Communities of Health (ACH)

What is an ACH?

Accountable Communities of Health (ACHs) bring together leaders from multiple health sectors around the state with a common interest in improving health and health equity. As ACHs better align resources and activities, they support wellness and a system that delivers care for the whole person.

There are nine ACHs. Their boundaries align with Washington’s Medicaid regional service areas. View the ACH regions map.


What are the goals of the ACHs?

  • Promote health equity throughout the state.
  • Create, support and collaborate on local health improvement plans.
  • Support local and statewide initiatives such as the Medicaid Transformation, practice transformation and value-based purchasing.
  • Align resources and activities that improve whole-person health and wellness.

How can ACHs serve the health needs of their regions?

Health system transformation depends on coordination and integration  with community services, social services and public health. ACHs provide  the necessary links and supportive environments to address the needs of the whole person.

How are ACHs involved with Medicaid transformation?

Each region, through its ACH will pursue projects aimed at transforming the Medicaid delivery system. Transformation projects will focus on health systems capacity building, care delivery redesign, prevention and health promotion, and increased use of value-based payment (VBP) models that reward providers for quality of care rather than the volume of services and procedures provided.
