The DC/Baltimore Corridor recorded 194 providers in the latest CMS NPI registry weekly update, representing 2% of the national weekly total. The registry lists 113 providers added this week and 131 added this year, including 173 individuals and 21 organizations. That concentration signals a substantial and active behavioral health market spanning Washington, Maryland and Virginia, although NPI records do not confirm whether a provider is practicing, accepting patients, staffing a site or offering ABA services.

ABA Credential Mix

The update identifies 10 BCBA providers and 69 RBT providers, with no dual BCBA-RBT credentials reported. The categories should not be treated as a complete or mutually exclusive workforce breakdown: 31 providers have multiple taxonomies, and other behavioral health credentials appear in the same registry. Even with that limitation, the RBT count is substantially larger than the BCBA count, suggesting greater direct-service capacity than supervisory capacity. For ABA operators, that pattern can support technician staffing while constraining caseload expansion if BCBA availability does not keep pace. The registry also includes assistant behavior analysts and providers with related mental health credentials.

Workforce Demographics

Women account for 118 providers, or 68% of the reported workforce. Men account for 27 providers, or 16%, while 28 providers, or 16%, are identified as nonbinary. No notable organization appears multiple times in the supplied data. Baltimore is the leading city with 50 providers, followed by Washington with 43; Alexandria has 11, while Pikesville and Silver Spring each have 10. The corridor’s expanding technician presence alongside a smaller BCBA pool suggests ABA access may increasingly depend on recruiting and retaining supervisors across its major urban centers.
