Common questions

Why is Neurodevelopmental Disabilities Physician a thin NUCC code in NPPES?

Only 45 NPIs list Neurodevelopmental Disabilities Physician as primary taxonomy across 22 states (peak California, 9). That is 580th 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 Neurodevelopmental Disabilities Physician NPIs in Open Payments look unusual?

CMS Open Payments 2024 lists 11 paid Neurodevelopmental Disabilities Physician physicians totaling $46K (175 payments; average $4K, 104th 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 Neurodevelopmental Disabilities Physician NPIs, 22 appear in the Medicare Part D Prescriber PUF (average 948 claims and $62K drug cost per prescriber; 84th of 496 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
