More than half of the CMS NPI records reviewed this week were newly added: 5,356 new records out of 10,322 records in the 2026-W33 file. The surge is concentrated in the current year, with 6,017 records carrying a 2026 enumeration year. That combination points to a behavioral health market expanding quickly, although the registry captures both newly enrolled providers and older records updated this week.

California Sets the Pace

California led the geographic field with 1,828 providers, or 18% of the week’s records. Texas followed with 743 providers, while Florida recorded 689. Michigan and Ohio were next, with 498 and 486 providers, respectively. North Carolina, New York, Washington, Colorado and Illinois rounded out the leading states.

The distribution reflects population, but not population alone. California’s large pediatric population and extensive behavioral health infrastructure support heavy enrollment activity. Florida’s strong showing is familiar to ABA operators: its Medicaid ABA reimbursement program, autism service demand and concentration of school-age children create powerful incentives for providers and organizations to establish a billable presence. The year-to-date figures tell the same story, with California recording 1,144 new providers, followed by Texas at 479 and Florida at 400.

At the same time, the leading states should not be mistaken for the entire market. The top-state table is heavily weighted toward large and well-developed service systems, while smaller states and rural areas appear in much lower volumes. That gap suggests uneven access and uneven organizational capacity, even as enrollment spreads across the country.

RBTs Outnumber Supervisors

RBT was the largest primary taxonomy, with 3,099 RBTs, representing 30% of primary-taxonomy records. Mental health counselors numbered 1,704, clinical social workers 1,702, and speech-language pathologists 994. The primary-taxonomy count for BCBAs was 707, or 7%.

Those categories overlap and are not mutually exclusive market shares. The registry identifies 1,932 providers with a second taxonomy and 727 providers with a third. The 91 dual BCBA-RBT providers illustrate a common ABA career path: an RBT advances to board certification and may retain the earlier designation. Because RBTs are underrepresented in federal registries compared with the actual workforce, the taxonomy data should be read as a credentialing snapshot, not a complete census of ABA personnel.

Gender data shows a workforce that remains predominantly female. Women accounted for 7,104 individuals, or 80%, compared with 1,379 men, or 15%, and 422 nonbinary individuals, or 5%. The pattern aligns with behavioral health’s ties to education, caregiving and other female-dominated professions.

Recent Enrollment Dominates

The enrollmentByYear field records when this week’s providers were originally enumerated, not a cumulative historical total. Older records can appear because a previously enrolled provider updated a record this week. Even with that caution, the recent concentration is striking: 2026 contributed 6,017 records, compared with 540 records from 2025 and 480 records from 2024. The pattern signals continued workforce entry and market expansion, particularly in high-demand services.

Multi-Site Organizations Surface

Repeated organization names show how enrollment is being operationalized. CREOKS MENTAL HEALTH SERVICES appeared 13 times, MYMICHIGAN MEDICAL CENTER SAGINAW 10 times, OPTUM BEHAVIORAL CARE OF COLORADO, P.C. 9 times, and EDUCARE COMMUNITY LIVING CORPORATION - TEXAS 8 times. These repetitions likely represent multiple locations, billing structures or service lines rather than separate independent companies. The presence of networked organizations alongside thousands of individuals shows a field scaling through both workforce growth and platform expansion.

Together, the data describes an industry with strong demand but growing operational complexity. More RBTs and BCBAs can expand supervised care, while counselors, social workers and speech-language pathologists reflect the multidisciplinary services surrounding ABA. For clinics and payers, the next challenge is turning rapid enrollment into credentialed, supervised and consistently reimbursed care.
