CMS NPPES recorded 77 deactivations in the Nurses segment during the week of Sept. 7 through Sept. 13, 2026. Hipa.ai’s name cache retrieved names for 76 records, meaning nearly all of the week’s deactivations could be identified by name. California and New York tied as the leading states, with 8 deactivations each. The file included 71 individual providers and 5 organizations.
California and New York Lead
California and New York each accounted for 11% of the weekly total, followed by Texas and Ohio with 6 deactivations apiece, or 8% each. Michigan ranked next with 5 records, or 7%. Florida, Oklahoma, Colorado and Washington each posted 3 deactivations, while Pennsylvania, New Mexico, Wisconsin, North Carolina, Delaware and Massachusetts each recorded 2.
The geographic distribution is broad rather than concentrated in a single market. The leading states include large, populous healthcare systems as well as states with substantial rural and regional provider networks. Houston, Albuquerque, Denver and Oklahoma City each appeared with 2 deactivations, the highest city-level count in the file. The pattern is consistent with registry activity spread across multiple workforce markets rather than a single localized event.
Registered Nurses Top Taxonomies
Registered Nurse was the leading retired taxonomy among named providers, with 16 records, or 21% of the named subset. Nurse Practitioner and Licensed Practical Nurse followed with 9 records each, representing 12% apiece. Family Nurse Practitioner accounted for 7 records, or 9%, while Certified Registered Nurse Anesthetist contributed 6, or 8%.
The mix spans direct nursing, advanced practice and specialized roles. Psychiatric/Mental Health Registered Nurse, Adult Health Nurse Practitioner and Home Health Registered Nurse each appeared 4 times, or 5%. Pediatric Nurse Practitioner and School Registered Nurse each accounted for 2 records, or 3%. The range shows that the week’s deactivations were not limited to one credential pathway or care setting.
What Deactivation Records Show
CMS provides the official deactivation count, but it removes names, addresses and taxonomy from most deactivated records under its privacy policy; the one-record difference here reflects that CMS count of 77 versus the 76 names captured in Hipa.ai’s cache before scrubbing.
An NPI deactivation is an administrative registry change, not by itself evidence of a license action, malpractice or the end of clinical work. Records may be retired as providers leave practice, change entities, consolidate organizations or obtain new NPIs. The weekly file therefore captures a combination of registry maintenance, workforce churn and multi-NPI re-registration, without establishing what happened to any specific provider.
