What the count covers

806 NPPES records list occupational therapy assistant (224Z00000X) as their primary taxonomy with a practice address in Washington: 10 per 100,000 residents against 12 nationally (50 states and D.C.). Seattle has 64 of them (8%).

A record is a registration a provider made and keeps up to date: it shows neither that the provider is licensed nor that they still practice there. The state's own license search is the check.
