Massachusetts recorded 8 physician NPI deactivations during the week of Sept. 14–20, 2026, accounting for 5% of the national total. All 8 records were for individuals; no organization deactivations were reported. The weekly count describes changes in the federal NPPES registry, not a confirmed change in the number of practicing physicians. A deactivation is an administrative status change and does not, by itself, indicate a license action or that a provider has stopped practicing.
Credentials and Cities
The credential breakdown was dispersed: anesthesiology, ophthalmology, pediatrics, psychiatry and child and adolescent psychiatry each had 1 deactivation. No listed specialty exceeded another in the reported top credentials. Boston had 2 records, the most of any city; Westwood, Medford, Chestnut Hill and Cambridge each had 1. The city and credential counts show a spread across specialties and locations, with a modest clustering in Boston, rather than a dominant specialty or city. The data does not establish why these records were deactivated or whether the providers’ practice arrangements changed.
Registry Context
CMS generally removes names, addresses and taxonomy information from most deactivated NPI records. Hipa.ai retains a name cache from public CMS files captured before deactivation, but the weekly totals remain registry counts. They should not be interpreted as a direct measure of active clinical capacity, patient access or departures from Massachusetts practice. The figures provide a snapshot of physician-record deactivations in the state for the reporting week.
