Washington recorded 275 providers in the latest CMS NPI registry weekly update, representing 3% of the national weekly total. The update includes 234 individuals and 41 organizations, with 127 new records this week and 144 added this year. Washington’s relatively large national share signals a substantial and active behavioral health market, although NPI activity does not confirm that providers are accepting patients, maintaining active caseloads or expanding service capacity.

ABA Workforce Mix

The registry reports 8 BCBA credentials and 52 RBT credentials, with no dual BCBA-RBT credentials. That is more than six RBT records for every BCBA record, a pattern that points to a technician-heavy ABA workforce and limited documented supervisory depth. Because BCBAs supervise RBTs, develop treatment plans and monitor clinical quality, a small BCBA pool can constrain how quickly technician growth becomes additional billable service capacity. The credential categories overlap with taxonomy fields and are not mutually exclusive shares of the provider total. For example, the data also includes BCBA records with LBA or LABA credentials, while 62 providers carry multiple taxonomies. The broader registry includes counselors, social workers, speech-language pathologists and addiction professionals, so the total is not an ABA-only count.

Demographics and Organizations

Women account for 183 providers, or 78%; men account for 46, or 20%; and five providers are nonbinary, or 2%. Gender is not reported for every provider record. Seattle, Spokane, Vancouver, Tacoma and Olympia are the leading listed cities, showing activity across both major population centers and regional markets. Sea Mar Community Health Centers appears six times, while Sendero Counseling Services and New Directions Counseling, LLC each appear twice, indicating recurring organizational activity rather than six or two separate provider networks.

Washington’s update suggests growing technician-level ABA capacity, but expanding access will depend on recruiting more BCBA supervisors and distributing them beyond the state’s largest cities.
