Frequently Asked Questions

Why is Orthopedic Assistant a thin NUCC code in NPPES?

Only 151 NPIs list Orthopedic Assistant as primary taxonomy across 35 states (peak California, 39). That is 484th 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 Orthopedic Assistant NPIs in Open Payments look unusual?

CMS Open Payments 2024 lists 6 paid Orthopedic Assistant physicians totaling $1K (23 payments; average $188, 469th 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 Orthopedic Assistant NPIs, 4 appear in the Medicare Part D Prescriber PUF (average 134 claims and $20K drug cost per prescriber; 469th of 572 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
