Obstetrics & Gynecology Nurse Practitioner: how many are there, and how many are in private practice?

National totals

Reading the sole-proprietor share

For this specialty, 350 of the 3,017 active records, or 11.6%, are flagged as sole proprietors in NPPES. The flag is a self-reported NPPES field and an imperfect proxy for private practice: it does not by itself establish ownership, employment arrangement, or independence. Use the percentage as a description of reported registration status, not as a direct estimate of how many Obstetrics & Gynecology Nurse Practitioners work in private practice.

By state

New NPI registrations by year

Counts reflect the year each NPI was first issued, among records still active today. The final year is partial: this data covers through 2026-01-11.

Data notes

• The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
• A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
• - The count covers active NPI records with this taxonomy as the primary taxonomy, not a census of all clinicians who provide obstetrics and gynecology care.
• - NPPES taxonomy and practice-status fields are reported data and may be incomplete, outdated, or inconsistently maintained.
• - First-enumeration totals show NPI registration timing and do not measure clinical volume, patient demand, or changes in the practicing workforce.
• Providers are counted once, by their primary taxonomy code only.
