Maryland had 227 providers in the latest CMS NPI registry weekly update, representing 2% of the national weekly total. The update records 134 new entries this week and 148 this year. That concentration points to a meaningful share of national registry activity, but NPI records track registrations—not confirmed hiring, staffing levels or available appointments.

ABA credential mix

The credential summary lists 11 BCBAs and 79 RBTs, plus 3 providers with both credentials. Those counts overlap: dual-credential providers may be included in the BCBA and RBT totals, so the categories are not separate workforce shares. The reported RBT-to-BCBA balance suggests a much larger technician pool than supervisory pool. RBT growth can expand direct-service capacity, but BCBAs remain essential to supervision and clinical oversight. The registry’s credential and taxonomy fields are not a census of active ABA staff, and the data does not establish each provider’s work setting or caseload.

Demographics and organizations

Women account for 124 providers (66%); men and nonbinary providers each account for 31 and 32, respectively (17% each). Maryland’s update includes 187 individuals and 40 organizations. Three organizations appear twice in the notable-org list: M Management Group LLC, Marathon Health LLC and MH Health Care Services, PC. Repeated entries may reflect separate registry records rather than distinct employers. Baltimore, Columbia, Silver Spring, Lanham and Owings Mills lead the listed cities.

The update points to a sizable RBT presence but a comparatively smaller BCBA pool, making supervisory recruitment and retention important to whether Maryland can translate registry growth into broader ABA access.
