Common questions
Why is Otorhinolaryngology & Head-Neck Registered Nurse a thin NUCC code in NPPES?
Only 34 NPIs list Otorhinolaryngology & Head-Neck Registered Nurse as primary taxonomy across 13 states (peak Texas, 12). That is 600th 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 Otorhinolaryngology & Head-Neck Registered Nurse NPIs in Open Payments look unusual?
CMS Open Payments 2024 lists 2 paid Otorhinolaryngology & Head-Neck Registered Nurse physicians totaling $3K (155 payments; average $1K, 186th 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 Otorhinolaryngology & Head-Neck Registered Nurse NPIs, 2 appear in the Medicare Part D Prescriber PUF (average 2,885 claims and $448K drug cost per prescriber; 21st of 496 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
