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 improve whole person health and wellness. See our video.

There are nine ACHs that collectively cover the entire state, with the boundaries of each aligned with the state’s Medicaid regional service areas (see ACH regions map below).

What are the ACH goals?

  • Promote health equity across the state.
  • Address issues that affect health through local health improvement plans.
  • Support local and statewide initiatives such as the Medicaid Transformation demonstration, practice transformation and value-based purchasing.
  • Better align resources and activities that improve whole person health and wellness.

How do ACHs align with Regional Service Areas?

ACHs consider the specific needs within their regional service areas and communities. Health system transformation depends upon coordination and integration at the delivery system level with community services, social services and public health. This can happen if ACHs build the necessary linkages and supportive environments to address the needs of the whole person.

How are ACHs involved with Medicaid transformation?

Initiative one of the demonstration builds incentives for providers who are committed to changing how they deliver care. Each region, through its Accountable Community of Health (ACH), will be able to 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.
