What is an ACH?

What is an Accountable Community of Health?

An Accountable Community of Health (ACH) is a regional collaboration of healthcare providers, community organizations, and local leaders working together to make health care better. They focus on more than just medical care. ACHs also work on things like housing, food access, and transportation—because these all affect health.

The ACH network was formally established in 2015 with funding from a State Innovation Models Round 2 test grant and supportive Washington state legislation in the 2014 session.

SWACH: Helping People Live Healthier Lives

Southwest Washington Accountable Community of Health (SWACH) serves Clark, Klickitat, and Skamania counties. We focus on health equity, which means making sure everyone has a fair chance to be healthy. We work with partners, listen to community voices, and support policies that improve health and remove barriers to care.

Working Together Across Washington

There are nine ACHs in the state. Each one serves a different area. They work together to:

  • Reduce unfair differences in health

  • Make care easier to get

  • Share ideas and resources

  • Support strong local health programs

Medicaid Transformation Project (MTP)

The Medicaid Transformation Project (MTP) is Washington State's Section 1115 Medicaid demonstration waiver, a partnership between the Health Care Authority (HCA) and the Centers for Medicare & Medicaid Services (CMS). Through MTP, the state invests in community health programs, payment reform efforts, and health care access improvements—with ACHs playing a central role in these initiatives.

MTP first launched in 2017 as a five-year pilot project to improve Medicaid delivery systems. The program was later renewed as MTP 2.0, expanding support for community health care services, behavioral health integration, and social determinants of health initiatives.
