Pediatric Cardiology Physician: how many are there, and how many are in private practice?

National totals

What this specialty covers

A pediatric cardiologist provides comprehensive care to patients with cardiovascular problems. This specialist is skilled in selecting, performing and evaluating the structural and functional assessment of the heart and blood vessels, and the clinical evaluation of cardiovascular disease.

Reading the sole-proprietor share

For this specialty, 388 records, or 12.8%, are flagged as sole proprietors. This is a self-reported NPPES field and an imperfect proxy for private practice, because it does not establish whether a provider works independently, belongs to a group, or owns a practice.

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.
• These figures count active NPI records and are not a verified census of practicing pediatric cardiologists.
• An NPI's registered location and first-enumeration year may not represent every location where care is delivered or when a provider began practicing.
• Providers are counted once, by their primary taxonomy code only.
