Common questions
Why is Nephrology Specialist/Technologist a thin NUCC code in NPPES?
Only 17 NPIs list Nephrology Specialist/Technologist as primary taxonomy across 13 states (peak New York, 3). That is 647th of 688 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 6 paid Nephrology Specialist/Technologist physicians totaling $3K (114 payments; average $579, 278th of 470 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 747 claims and $115K drug cost per prescriber; 119th of 496 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
