The DC/Baltimore Corridor has 240 providers in the latest CMS NPI registry update, representing 2% of the national weekly total. The registry reports 114 providers added this week and 137 this year; its area-wide total includes 195 individuals and 45 organizations. That reported national share points to a substantial concentration of behavioral health listings across DC, Maryland and Virginia, though NPI records alone do not confirm active practice, patient availability or ABA service delivery.

ABA Credential Mix

The registry lists 10 BCBA providers and 84 RBT providers, with no dual BCBA-and-RBT credentials reported. Credential counts can overlap when a provider holds more than one classification, so they should not be read as mutually exclusive workforce shares. The gap between listed RBTs and BCBAs suggests a workforce weighted toward direct-care roles, with a comparatively smaller pool of credentialed supervisors to oversee services. That distinction matters for clinic capacity: RBT availability does not itself establish that supervision capacity is keeping pace. The data also flags 46 providers with multiple taxonomies, another reason not to treat registry categories as separate groups.

Workforce and Geography

Women account for 149 listed providers, men 32 and nonbinary providers 14; the corresponding reported shares are 76%, 16% and 7%, which do not sum to 100% because of rounding. Community Behavioral Health, LLC appears six times, while Community Behavioral Health appears four times; the registry presents these as separate organization names. The largest city counts are Washington, with 41 providers, Columbia with 27, Baltimore with 25 and Pikesville with 22. No corporate-headquarters city skew is identified in the supplied data. Overall, the corridor’s listings suggest broad provider activity but a potential ABA access constraint if supervisory capacity does not grow alongside the RBT workforce.
