Electroneurodiagnostic Specialist/Technologist: how many are there, and how many are in private practice?

National totals

Reading the sole-proprietor share

For this specialty, 20.5% of the active NPI records, or 926 records, are marked as sole proprietors in NPPES. This is an imperfect proxy for private practice: the field is self-reported and does not establish ownership, employment status, or how a provider delivers services.

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.
• - NPPES records are not a direct headcount of unique clinicians, practices, or staffed positions.
• - NUCC publishes no official definition for 246ZE0600X, so the taxonomy's scope may not be uniform across records.
• Providers are counted once, by their primary taxonomy code only.
