Washington recorded 288 providers in the latest CMS NPI registry weekly update, representing 3% of the national weekly total. The registry includes 111 new providers this week, with 232 individuals and 56 organizations. That concentration places Washington among the more active state markets in this update and signals meaningful provider movement for hiring, contracting and service development. NPI activity does not confirm that a provider is accepting referrals or has available appointment capacity.

ABA Workforce Mix

The credential file lists 7 BCBAs, 45 RBTs and 3 dual BCBA-RBT credentials. These counts overlap and are not mutually exclusive shares of the 288-provider total; taxonomy and credential fields can identify the same provider in different ways. The wide gap between BCBAs and RBTs points to a workforce weighted toward direct implementation rather than clinical supervision. Because BCBAs supervise RBTs, design and update treatment plans, and monitor treatment quality, the relatively small BCBA count may limit how quickly Washington clinics can expand services. The 3 dual credentials indicate some progression between technician and advanced behavior-analytic roles, but the count is modest.

Demographics and Organizations

Gender data identifies 181 providers as female, 43 as male and 8 as nonbinary, corresponding to 78%, 19% and 3%. The listed cities are Seattle, Spokane, Tacoma, Vancouver and Bellevue, showing activity across major urban centers as well as surrounding communities. Sea Mar Community Health Centers appears 19 times, making it the most frequently repeated organization in the registry. Those entries represent separate organizational NPIs and should not be read as 19 independent employers or equivalent measures of clinical capacity. The registry also reports 109 providers with multiple taxonomies, reinforcing the need for caution when interpreting category totals.

Washington’s RBT-heavy mix suggests continued direct-service workforce availability, while limited BCBA representation may remain a constraint on broader ABA access.
