The Washington State All Payer Claims Database (WA-APCD) is a tool used to collect health care claims data for reporting, analytics, and to help the public make their health care decisions. It supports health care and payment reform while addressing the need for cost, quality, and utilization transparency.

The WA-APCD began in 2014 when the Washington State Legislature passed landmark legislation that directed the Office of Financial Management (OFM) to establish and create the database.

The Washington State Health Care Authority (HCA) and Office of Financial Management (OFM) transitioned management of the WA-APCD from OFM to HCA. HCA has been in lead organization negotiations with the Washington Health Alliance. We have not reached agreement. As such, program contracts have been assigned to HCA in the interim as we continue negotiations.

Washington HealthCareCompare, winner of the 2018 National Association of Health Data Organizations "Innovation in Data Dissemination Award," is an online tool (based on WA-APCD data) to improve health care cost and quality transparency. Search over 100 procedures and treatments for cost information and examine quality ratings of providers and hospitals. The site also includes results for the Statewide Common Measure Set.
