Obstetrics Physician: how many are there, and how many are in private practice?

National totals

What this specialty covers

A physician who specializes in diagnosis, treatment, and management of patients with obstetric conditions.

Reading the sole-proprietor share

For this specialty, 15.6% of active records are flagged as sole proprietors, meaning the NPI holder reported that status in NPPES. This share can inform questions about business form among obstetrics physicians, but it is an imperfect proxy for private practice because it may not capture employment, group affiliation, ownership, or how a clinician actually practices.

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.
• NPI records and taxonomy assignments reflect NPPES registrations and can change over time.
• A primary taxonomy describes the classification reported for the NPI, not necessarily the clinician's full scope of practice or current clinical activity.
• Providers are counted once, by their primary taxonomy code only.
