Common questions
Why is Radiological Physics Physician a thin NUCC code in NPPES?
Only 119 NPIs list Radiological Physics Physician as primary taxonomy across 25 states (peak Florida, 29). That is 505th 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 Radiological Physics Physician NPIs in Open Payments look unusual?
CMS Open Payments 2024 lists 9 paid Radiological Physics Physician physicians totaling $14K (18 payments; average $2K, 180th 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 Radiological Physics Physician NPIs, 2 appear in the Medicare Part D Prescriber PUF (average 24 claims and $257 drug cost per prescriber; 460th of 496 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
