About the APCD Snapshot & Its Data

This Snapshot of the Washington All-Payer Health Care Claims Database (WA-APCD) is a quick and easy way to explore how healthcare is being delivered and consumed across the state. 

Using the Snapshot’s dashboards, you can quickly explore what data is available, how many people have insurance from year to year, which medical procedures are being performed, and which drugs are being prescribed most often – and what all of this costs for health plans and consumers. For an explanation of key terms and measures used across the dashboard, simply click the "Additional Information" tab provided below the Snapshot.

This Snapshot is updated quarterly and uses data from the WA-APCD, which is the state’s most complete source of medical, pharmacy, and dental insurance data. It includes both Washington residents and out-of-state members covered by plans based in Washington.
