Common questions
Why is Cardiovascular Invasive Specialist/Technologist a thin NUCC code in NPPES?
Only 74 NPIs list Cardiovascular Invasive Specialist/Technologist as primary taxonomy across 23 states (peak Colorado, 28). That is 544th 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 Cardiovascular Invasive Specialist/Technologist NPIs in Open Payments look unusual?
CMS Open Payments 2024 lists 2 paid Cardiovascular Invasive Specialist/Technologist physicians totaling $775 (28 payments; average $388, 306th 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 Cardiovascular Invasive Specialist/Technologist NPIs, 3 appear in the Medicare Part D Prescriber PUF (average 3,849 claims and $627K drug cost per prescriber; 10th of 496 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
