Frequently Asked Questions

Why is Medical Microbiology Physician a thin NUCC code in NPPES?
Only 90 NPIs list Medical Microbiology Physician as primary taxonomy across 33 states (peak New York, 8). That is 542nd 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 Medical Microbiology Physician NPIs in Open Payments look unusual?
CMS Open Payments 2024 lists 9 paid Medical Microbiology Physician physicians totaling $35K (32 payments; average $4K, 118th 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 Microbiology Physician NPIs, 4 appear in the Medicare Part D Prescriber PUF (average 4,175 claims and $248K drug cost per prescriber; 14th of 572 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
