Emergency Registered Nurse: how many are there, and how many are in private practice?

National totals

Reading the sole-proprietor share

For this specialty, 1,410 records, or 33.1%, carry the sole-proprietor indicator in NPPES. Because that field is self-reported, the percentage is an imperfect proxy for private practice and does not by itself show whether an Emergency Registered Nurse works independently, belongs to a group, or is employed by a hospital or other organization. Use it as a description of NPPES reporting, not as a definitive measure of employment arrangements.

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 count covers active NPI records using 163WE0003X as the primary taxonomy, not every clinician who may perform emergency nursing work.
• NUCC publishes no official definition for this taxonomy, so the classification should be interpreted cautiously.
• Providers are counted once, by their primary taxonomy code only.
