Frequently Asked Questions

Why is Nephrology Specialist/Technologist a thin NUCC code in NPPES?

Only 17 NPIs list Nephrology Specialist/Technologist as primary taxonomy across 14 states (peak New York, 3). That is 657th of 690 NUCC codes by headcount. Thin codes are still searchable by NPI; do not treat the low count as a quality signal.

Do the few Nephrology Specialist/Technologist NPIs in Open Payments look unusual?

CMS Open Payments 2024 lists 7 paid Nephrology Specialist/Technologist physicians totaling $16K (206 payments; average $2K, 184th of 551 by average). Presence is not a quality judgment; thin specialties often have sparse payment rows.

How much Part D prescribing does this specialty do?

Among Nephrology Specialist/Technologist NPIs, 8 appear in the Medicare Part D Prescriber PUF (average 1,199 claims and $272K drug cost per prescriber; 111th of 572 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
