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

National totals

What this specialty covers

An obstetrician/gynecologist who is capable of managing complex problems relating to reproductive endocrinology and infertility.

Reading the sole-proprietor share

For this specialty, 304 of 2,026 active records, or 15.0%, are flagged as sole proprietors. The flag is a self-reported NPPES field and is an imperfect proxy for private practice: it does not by itself show that a physician owns a practice, works independently, or lacks an organizational affiliation.

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.
• Counts are limited to active NPI records whose primary taxonomy is 207VE0102X.
• NPI records are administrative identifiers and do not measure full-time equivalents, patient volume, or distinct practice sites.
• Providers are counted once, by their primary taxonomy code only.
