The DC/Baltimore Corridor has 224 providers in the latest CMS NPI registry weekly update, representing 2% of the national weekly total. The registry records 123 providers new this week and 136 new this year; the area’s total includes 189 individuals and 35 organizations. That concentration points to a substantial regional provider presence across DC, Maryland and Virginia, but NPI records do not confirm active practice, staffing or service availability.

ABA Credential Mix

The update lists 13 BCBA providers and 68 RBT providers, including 2 dual-credential providers. These categories overlap: dual-credential providers appear in both counts, so they are not separate workforce shares. The larger RBT count suggests a broader listed direct-care workforce than supervisory pool. Because BCBAs supervise RBTs, that imbalance may make supervisory capacity a factor in expanding services, though registry credentials do not establish current job duties. The data also lists 47 providers with multiple taxonomies, another reason not to treat classifications as mutually exclusive.

Workforce Demographics

Among individuals, 131 are listed as female, 28 as male and 30 as nonbinary; these are counts, not a breakdown of all provider records. HOMECARE DMV, Inc. is the only organization in the notable-organizations data appearing more than once, with two records. Washington leads the listed cities with 49 providers, followed by Baltimore with 34, Columbia with 17, Silver Spring with 12 and Fairfax with 10. The broad geographic spread and sizable RBT listing suggest a substantial direct-care workforce, while the smaller BCBA count underscores the importance of supervisory capacity to ABA access across the corridor.
