Arizona recorded 171 providers in the latest CMS NPI registry weekly update, accounting for 2% of the national weekly total. With 87 new providers added this week, Arizona represents a meaningful concentration of registry activity and signals continued behavioral health expansion in a large, growing service market.

ABA Workforce Mix

The registry reports 23 BCBA credentials and 57 RBT credentials, including 1 dual credential held by a provider listed as both BCBA and RBT. These categories are not mutually exclusive: credential and taxonomy fields can overlap, and the overall provider count includes other behavioral health professionals. The 24 providers with multiple taxonomies further underscore that limitation. Even so, the RBT-to-BCBA pattern points to a substantially larger direct-service workforce than supervisory workforce. Because BCBAs oversee RBTs, treatment planning and clinical quality, the mix suggests that supervision capacity could constrain how quickly Arizona converts workforce growth into expanded ABA caseloads.

Demographics and Provider Activity

Arizona’s registry includes 138 individuals and 33 organizations. Gender data identifies 117 female providers, 19 male providers and 2 nonbinary providers, corresponding to 85%, 14% and 1%. The gender figures total 138, matching the individual-provider count. Phoenix, Tucson, Mesa, Chandler and Scottsdale lead the listed city activity, while providers also appear in Yuma, Flagstaff, Sierra Vista and other markets. No notable organization is identified as appearing multiple times in the registry update.

Arizona’s strong weekly additions, especially among RBTs, suggest potential gains in ABA access, but the comparatively smaller BCBA pool points to supervision and clinical leadership as continuing workforce priorities.
