Frequently Asked Questions

Why is Medical Toxicology (Preventive Medicine) Physician a thin NUCC code in NPPES?
Only 27 NPIs list Medical Toxicology (Preventive Medicine) Physician as primary taxonomy across 13 states (peak California, 6). That is 627th of 690 NUCC codes by headcount. Thin codes are still searchable by NPI; do not treat the low count as a quality signal.

CMS Open Payments 2024 lists 1 paid Medical Toxicology (Preventive Medicine) Physician physicians totaling $21 (3 payments; average $21, 545th 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 Medical Toxicology (Preventive Medicine) Physician NPIs, 8 appear in the Medicare Part D Prescriber PUF (average 156 claims and $23K drug cost per prescriber; 455th of 572 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
