The latest update to the CMS National Provider Identifier (NPI) registry for the week of March 23-29, 2026, shows a total of 73 NPI deactivations within the Nurses segment. Of these, 72 records had names retrievable by Hipa.ai's cache before CMS removed identifying information from the public record, with one record being scrubbed. The majority of deactivations, 70, were for individual nurses, while 2 were for organizations. New York led the states with the highest number of deactivations, accounting for 13 records, or 18% of the national total.
Geographic Distribution of Deactivations
Beyond New York's leading count of 13 deactivations, several other states also reported notable activity. California followed with 8 deactivations, representing 11% of the total. Florida recorded 6 deactivations, or 8%. Pennsylvania and Arizona each saw 4 deactivations, making up 6% of the total respectively. States such as South Carolina, Texas, Illinois, Iowa, and Washington each registered 3 deactivations, contributing 4% to the overall count. This geographic spread suggests deactivations are occurring across diverse regions, often in states with large populations and significant healthcare workforces.
Key Nursing Specialties Affected
An analysis of the taxonomy codes associated with the named deactivated records reveals a mix of nursing specialties. The most frequently deactivated taxonomy was 163W00000X, representing Registered Nurses, with 16 instances, or 22% of the named records. Licensed Practical Nurses (164W00000X) followed with 12 deactivations, accounting for 17%. Nurse Practitioners (363L00000X) saw 7 deactivations, or 10%, while Nurse Anesthetists (367500000X) had 6 deactivations, making up 8%. Family Nurse Practitioners (363LF0000X) accounted for 5 deactivations, or 7%. This distribution indicates deactivations across general nursing roles as well as advanced practice specialties.
Understanding NPI Registry Changes
NPI deactivations are an administrative process in the federal NPPES registry and do not inherently signify license actions, malpractice, or that a provider has ceased practice. Providers may obtain a new NPI, retire, change their entity type, or have their record retired for clerical reasons. As the NPI registry continues to age and evolve, an annual increase in deactivations is a consistent trend, reflecting ongoing workforce churn, administrative updates, and the natural lifecycle of provider registration within the U.S. healthcare system.
