The WA-APCD was established in 2014 when the Washington State Legislature passed legislation directing the Office of Financial Management (OFM) to establish and create the database. In 2019, management of those efforts moved from OFM to the  Washington State Health Care Authority (HCA), Washington's Medicaid program.
