Washington recorded 253 providers in the latest CMS NPI registry weekly update, representing 3% of the national weekly total. The update includes 108 providers added this week and 138 added this year, with 220 individuals and 33 organizations. That concentration signals a substantial level of behavioral health registry activity in Washington, although NPI records do not confirm active caseloads, staffing levels or appointment availability. The leading cities listed are Seattle, Spokane, Vancouver, Tacoma and Tukwila.

ABA Workforce Mix

The credential summary reports 5 BCBAs and 57 RBTs, with no dual BCBA-RBT credentials. These figures should be read cautiously: the registry’s credential-text field reports 2 BCBA and 2 RBT entries, and credential and taxonomy fields can classify the same provider differently. The categories are not mutually exclusive. Even using the summary counts, Washington shows a technician-heavy ABA profile, with many more RBT records than BCBA records. That pattern can support direct service delivery, but it also points to a limited documented supervisory pool because BCBAs oversee RBT practice, treatment planning and clinical quality. The registry identifies 68 providers with multiple taxonomies, another indication that provider roles overlap.

Demographics and Organizations

Women account for 155 providers, or 70% of the reported workforce. Men account for 52 providers, or 24%, while 13 providers are nonbinary, or 6%. No notable organization appears multiple times in the update, so the records do not point to a repeated dominant employer. The mix instead includes numerous individual providers alongside 33 organizations.

Washington’s update suggests growing behavioral health participation but a relatively small documented BCBA base, making supervisory recruitment important to expanding reliable ABA access.
