Michigan recorded 652 providers in the latest CMS NPI registry weekly update, representing 6% of the national weekly total. The file lists 437 providers added this week and 465 added this year; 607 are individuals and 45 are organizations. That concentration points to substantial registry activity in Michigan, but NPI records do not establish hiring, active staffing, caseloads or appointment availability.

ABA Workforce Mix

The credential summary lists 22 BCBAs, 319 RBTs and 5 providers with dual BCBA-RBT credentials. These categories overlap: dual-credential providers are included in the broader BCBA and RBT counts, so they are not a separate workforce share. The RBT total far exceeds the BCBA count, indicating a technician-heavy profile and a comparatively limited supervisory pool. RBT growth can expand direct-service capacity, but BCBAs must supervise RBTs and guide clinical programming; the imbalance makes supervisory capacity a potential constraint on turning workforce additions into more ABA services. The file also reports 65 providers with multiple taxonomies, reinforcing that classifications can overlap.

Demographics and Organizations

Women account for 506 providers, or 83%; men account for 77, or 13%; and nonbinary providers account for 24, or 4%. Among organizations identified as notable, Munson Medical Center appears twice. Repeated entries may reflect multiple registry records for an organization, rather than separate employers. Farmington Hills, Grand Rapids, Southfield, Ann Arbor and Saginaw are the leading listed cities, while the wider provider file includes a geographic spread beyond those centers.

Michigan’s update suggests a large, technician-rich workforce, but expanding ABA access will depend in part on maintaining enough BCBA supervision as RBT capacity grows.
