All-Payer Health Care Claims Database Program - Background


Contact information

RCW 43.371.020, directs the Office of Financial Management (OFM) to establish a statewide all payer health care claims database (WA-APCD) to support transparent public reporting of health care information. The purpose of the database is to improve health care price transparency and to:

  • Assist patients, providers, and hospitals to make informed choices about care
  • Enable providers, hospitals, and communities to improve by benchmarking their performance against that of others by focusing on best practice
  • Enable purchasers to identify value, build expectations into their purchasing strategy, and reward improvements over time
  • Promote competition based on quality and cost

The database will systematically collect all medical claims, pharmacy claims, and dental claims from private and public payers, with data from all settings of care that permit the systematic analysis of health care delivery.

The law also required OFM to use a competitive procurement process to select a lead organization to coordinate and manage the database, and a data vendor who is subcontracted to the lead organization to establish and operate the WA-APCD system. In July 2016 OFM selected Oregon Health and Science University’s (OHSU) Center for Health Systems Effectiveness (CHSE) as the lead organization and Onpoint Health Data as the data vendor.

Data from the WA-APCD database is available online at the Washington HealthCareCompare website to allow Washington residents to search for health care costs of over 100 procedures and treatments and see quality ratings of providers and hospitals. Visitors to the site can also see results for the Washington State Common Measures Set results by Accountable Communities of Health (ACH) and by type of insurance coverage.
