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

National totals

What this specialty covers

The NUCC recommends this code not be used. Choose a more appropriate code.

Reading the sole-proprietor share

For this specialty, the sole-proprietor share means that the NPPES record is flagged as a sole proprietor, not that the physician definitely owns or works in a private practice. Because the field is self-reported and the taxonomy is recommended not to be used, the share is an imperfect proxy for private practice. It does not show practice size, employment arrangement, or clinical activity.

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 NUCC recommends that this taxonomy code not be used, so coding may be inconsistent across providers and organizations.
• - An active NPI does not by itself establish current clinical activity, patient volume, or availability.
• - Providers may have multiple taxonomies or practice relationships, and the primary taxonomy may not describe their full work.
• Providers are counted once, by their primary taxonomy code only.
