End-Stage Renal Disease (ESRD) Treatment Clinic/Center: how many are there, and how many are in private practice?

National totals

Reading the sole-proprietor share

For this specialty, 0 active records, or 0.0%, are flagged as sole proprietors in NPPES. That field is self-reported and is an imperfect proxy for private practice: a zero share does not establish that no clinicians work independently, nor does it describe the ownership, employment, or legal structure of every center.

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.
• An NPI record is not necessarily a unique physical clinic, organization, or location.
• The primary taxonomy is reported in NPPES and may not capture every service a center provides.
• An NPI enumeration year is not the same as an opening date, and NPPES records can change over time.
• Providers are counted once, by their primary taxonomy code only.
