The CMS National Provider Identifier (NPI) registry recorded 61 NPI deactivations in the Nurses segment during the week of March 9-15, 2026. Of these, 60 records had retrievable names, with 1 record scrubbed by CMS in accordance with its privacy policy. The majority of deactivations, 54, were for individual providers, while 6 were for organizational entities. New York led all states with 8 deactivations, representing 13% of the total.
Geographic Distribution of Deactivations
Following New York's 8 deactivations, California recorded the second-highest number with 5, accounting for 8% of the total. Arizona followed with 4 deactivations, or 7%. A notable cluster of six states each reported 3 deactivations: Georgia, Massachusetts, Maryland, Colorado, Texas, and Iowa, each representing 5% of the week's total. Additionally, Missouri, Michigan, Indiana, Alabama, Ohio, and Kentucky each saw 2 deactivations, individually contributing 3%. This widespread distribution across 15 different states suggests that NPI deactivations are a routine administrative process affecting the nursing workforce across diverse regions of the U.S.
Key Nursing Taxonomy Deactivations
Among the 60 named deactivated records, individual providers accounted for 54, while 6 were organizational entities. The "Registered Nurse" taxonomy (163W00000X) was the most frequent among individuals, accounting for 18 deactivations, or 30% of the named records. This was followed by "Nurse Practitioner, Family" (363LF0000X) with 8 deactivations (13%), and "Certified Registered Nurse Anesthetist" (367500000X) with 7 deactivations (12%). Other significant categories included "Nurse Practitioner" (363L00000X) with 4 deactivations (7%), and "Nurse Practitioner, Psychiatric/Mental Health" (363LP0808X), "Licensed Practical Nurse" (164W00000X), "Nurse Practitioner, Adult Health" (363LA2200X), and "Registered Nurse, Psychiatric/Mental Health" (163WP0808X), each with 3 deactivations (5%). This diverse mix of taxonomy codes highlights the breadth of roles within the nursing profession affected by administrative NPI changes.
Context of NPI Deactivations
NPI deactivations are administrative actions within the federal registry and do not inherently indicate license actions, malpractice, or that a provider has ceased practicing. Providers may obtain new NPIs, retire, change their entity type, or have their records retired for clerical reasons. As the NPPES registry continues to age, and as healthcare professionals navigate career changes or practice consolidations, an ongoing level of deactivations is a regular aspect of registry maintenance and reflects the dynamic nature of the U.S. healthcare workforce.
