Multi-Specialty Clinic/Center: how many are there, and how many are in private practice?

National totals

Reading the sole-proprietor share

For this specialty, 122 of 9,495 active records, or 1.3%, are flagged as sole proprietors in NPPES. Because this field is self-reported and does not fully describe ownership, employment, or billing structure, the share is an imperfect proxy for private practice rather than a direct count of independently owned 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.
• These are active NPI records with 261QM1300X as the primary taxonomy, not a census of distinct clinics, sites, clinicians, or service volume.
• NUCC has not published an official definition for this taxonomy, and NPI records can be updated or reclassified over time.
• Providers are counted once, by their primary taxonomy code only.
