Common questions
Why is Medical Toxicology (Preventive Medicine) Physician a thin NUCC code in NPPES?
Only 32 NPIs list Medical Toxicology (Preventive Medicine) Physician as primary taxonomy across 14 states (peak New York, 6). That is 603rd 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 Medical Toxicology (Preventive Medicine) Physician NPIs in Open Payments look unusual?
CMS Open Payments 2024 lists 1 paid Medical Toxicology (Preventive Medicine) Physician physicians totaling $243 (2 payments; average $243, 345th 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 Medical Toxicology (Preventive Medicine) Physician NPIs, 10 appear in the Medicare Part D Prescriber PUF (average 147 claims and $20K drug cost per prescriber; 313th of 496 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
