Statewide totals

Active NPI records112,887
Registered sole proprietors30,210 (26.8%)

The sole-proprietor flag is self-reported, so the 26.8% share should be read as a registry classification rather than a direct count of private practices. It is an imperfect proxy and may not capture every practice's ownership or operating structure.
