Common questions
Why is Multi-Specialty Group a thin NUCC code in NPPES?
Only 10 NPIs list Multi-Specialty Group as primary taxonomy across 8 states (peak California, 3). That is 665th 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 Multi-Specialty Group NPIs in Open Payments look unusual?
CMS Open Payments 2024 lists 5 paid Multi-Specialty Group physicians totaling $17K (121 payments; average $3K, 123rd 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 Multi-Specialty Group NPIs, 7 appear in the Medicare Part D Prescriber PUF (average 2,424 claims and $334K drug cost per prescriber; 28th of 496 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
