Common questions
Why is Nephrology Registered Nurse a thin NUCC code in NPPES?
Only 141 NPIs list Nephrology Registered Nurse as primary taxonomy across 37 states (peak Texas, 14). That is 494th 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 Registered Nurse NPIs in Open Payments look unusual?
CMS Open Payments 2024 lists 22 paid Nephrology Registered Nurse physicians totaling $10K (377 payments; average $474, 368th 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 Registered Nurse NPIs, 26 appear in the Medicare Part D Prescriber PUF (average 1,241 claims and $197K drug cost per prescriber; 105th of 572 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
