Statewide totals

Active NPI records43,654
Registered sole proprietors10,405 (23.8%)

The sole-proprietor flag is self-reported, so the 23.8% share should be read as a registry classification rather than a complete measure of private practice in Idaho. It is an imperfect proxy and may not capture every practice's ownership or operating arrangement.
