Maryland recorded 444 providers in the latest CMS NPI registry weekly update, representing 4% of the national weekly total. The update includes 320 new providers this week and 344 added this year, with 402 individuals and 42 organizations. That concentration places Maryland among the more active state markets in this update, although NPI activity does not confirm active caseloads, staffing levels or appointment availability. The unusually large weekly intake may also reflect clustered registration activity rather than an equivalent expansion of clinical capacity.

ABA Workforce Mix

The credential summary lists 12 BCBAs and 279 RBTs, with no dual BCBA-RBT credentials. Two entries list BCBA, LBA credentials, and the registry’s credential-text fields separately report BCBA and BCBA, LBA counts; these classifications overlap and should not be treated as mutually exclusive shares of Maryland’s provider total. The gap between supervisory and technician-level records indicates a workforce built heavily around direct implementation. Because BCBAs supervise RBTs, the documented supervisor pool may constrain how many technician teams can be supported, even as the RBT pipeline expands. The broader registry also includes counselors, clinical social workers, psychologists and speech-language pathologists.

Demographics and Organizations

Gender data identifies 315 female providers, 60 male providers and 27 nonbinary providers, corresponding to 78%, 15% and 7%. Rockville, Baltimore, Columbia, Pikesville and Lanham are the listed top cities. Sisters in Action LLC appears three times, while Randall Therapeutic Services LLC appears twice. The registry reports 50 providers with multiple taxonomies, another overlap that does not represent 50 additional providers.

Maryland’s update suggests strong technician-level growth but limited documented BCBA depth, making supervisory recruitment and geographic distribution central to expanding ABA access.
