Maryland recorded 485 providers in the latest CMS NPI registry weekly update, representing 5% of the national weekly total. The registry lists 386 providers added this week and 402 added this year, alongside 440 individuals and 45 organizations. That concentration makes Maryland a significant regional behavioral health market, where provider growth can affect hiring, contracting and access. NPI activity does not by itself confirm active caseloads, clinical availability or service capacity.

ABA Workforce Mix

The credential data lists 14 BCBA credentials, 354 RBT credentials and 3 dual BCBA-RBT credentials. These categories overlap: dual-credentialed providers can be counted in both credential groups, and credential and taxonomy fields may describe the same provider differently. They should not be treated as mutually exclusive shares of the provider total. Even with that limitation, the pattern shows a far larger RBT direct-service workforce than BCBA supervisory workforce. Because BCBAs supervise RBTs and oversee treatment planning and clinical quality, the imbalance suggests that supervisory capacity could constrain how quickly Maryland converts RBT growth into expanded ABA services.

Demographics and Provider Activity

Among individual providers, the registry identifies 351 female, 63 male and 26 nonbinary providers, corresponding to 80%, 14% and 6%. The counts total 440 individuals. Rockville, Baltimore, Pikesville, Columbia and Frederick are the leading listed cities, with an especially large cluster of RBT entries in Rockville. Repeated organizations include Frederick Behavioral Health Services, LLC and Sisters in Action LLC, each appearing 3 times. Care Solutions Corporation, Arise & Shine Health Center LLC and Better Morning each appear twice.

Maryland’s RBT-heavy registry activity points to a growing direct-service pipeline, while limited BCBA representation makes supervision and career progression central to future ABA access.
