Reading the sole-proprietor share
For Urology Physician records, 2,374 of 17,852 active primary-taxonomy NPIs, or 13.3%, carry the sole-proprietor designation. This is a self-reported NPPES field, so it is an imperfect proxy for private practice and does not fully describe group ownership, employment, or other practice arrangements.

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 NPI records with the specialty as the primary taxonomy, not a guaranteed count of unique, currently practicing urologists.
- - First-enumeration and state counts describe registry records and do not measure net entry, clinical capacity, patient access, or causation.
- Providers are counted once, by their primary taxonomy code only.
Common questions
How many urologists are there in the US?
There are 17,852 active NPI records nationally with Urology Physician as the primary taxonomy. This is a count of records, not necessarily a count of unique practicing physicians.
How many urologists are in private practice?
NPPES flags 2,374 records, or 13.3%, as sole proprietors. That share is an imperfect proxy for private practice because the flag is self-reported and does not capture every ownership or employment arrangement.
Which states have the most urology physicians?
The largest state counts shown are California with 1,810 records, Florida with 1,470, and New York with 1,357. These are counts of NPI records associated with the specialty.
How many new urology physicians are there each year?
NPIs first enumerated in the listed recent full years numbered 182 in 2023, 239 in 2024, and 229 in 2025. First enumeration does not necessarily mean a new physician entered practice or that the specialty grew by that amount.
