How the change is counted
Each individual (Type 1) NPI is counted in the calendar year of its NPPES enumeration date, under its primary taxonomy. Only specialties with at least 100 new NPIs in 2024 are ranked, so small counts do not produce large percentages. A specialty can gain or lose volume when providers pick a different taxonomy label, without any change in staffing.
Common questions
Which specialty added the most new NPIs in 2025?
Behavior Technician: 114,687 new NPIs in 2025, +22,775 on 2024 (91,912).
Which specialty fell the most?
Family Nurse Practitioner: 13,152 new NPIs in 2025, -1,384 on 2024.
Is this the number of practicing providers?
No. It counts NPIs first issued in each calendar year (the NPPES enumeration date), not the number of active providers. A change of taxonomy label can also move volume between specialties.
