Vascular & Interventional Radiology Physician: how many are there, and how many are in private practice?

National totals

What this specialty covers

A radiologist who diagnoses and treats diseases by various radiologic imaging modalities. These include fluoroscopy, digital radiography, computed tomography, sonography and magnetic resonance imaging.

Reading the sole-proprietor share

For this specialty, the sole-proprietor share indicates how many active NPI records with this primary taxonomy are marked as sole proprietors in NPPES. It is a rough administrative signal, not a direct measure of private practice, because the field is self-reported and providers may work in multiple settings or use organizational NPIs.

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.
• - Providers may have multiple NPIs or taxonomies, so NPI records are not a complete headcount of individual physicians.
• - A primary taxonomy designation may not capture every service or specialty a provider offers.
• Providers are counted once, by their primary taxonomy code only.
