Maryland recorded 229 providers in the latest CMS NPI registry weekly update, representing 2% of the national weekly total. The state added 131 new providers this week, a level of activity that places Maryland among the more visible contributors to national behavioral health registry growth. The concentration reflects an active and expanding provider market, particularly across the Baltimore-Washington corridor, though the registry includes multiple behavioral health disciplines rather than ABA providers alone.

ABA Workforce Mix

The registry reports 16 BCBA credentials and 97 RBT credentials, along with 4 dual credentials held by providers listed as both BCBA and RBT. These categories overlap and are not mutually exclusive; credential and taxonomy fields can describe the same provider, and the broader total includes counselors, social workers, speech-language pathologists and other professionals. Even with that limitation, the RBT-to-BCBA pattern points to a much larger direct-service workforce than supervisory workforce. Because BCBAs oversee RBTs and treatment planning, the imbalance may constrain how quickly Maryland clinics can convert RBT growth into additional supervised ABA capacity.

Demographics and Provider Activity

Of Maryland’s 191 individuals, gender data identifies 144 as female, 27 as male and 20 as nonbinary, corresponding to 75%, 14% and 10%. The registry also lists 38 organizations, and 38 providers have multiple taxonomies, reinforcing the need to avoid treating categories as discrete shares. Baltimore, Columbia, Silver Spring, Rockville and Gaithersburg lead the listed cities. Sisters in Action LLC and Pomelo PC each appear twice among notable organizations, indicating repeated organizational activity rather than two separate providers in each case.

Overall, Maryland’s strong RBT presence and broad provider activity suggest improving ABA access, while limited BCBA representation could make supervision capacity the next workforce bottleneck.
