Common questions
Why is Perinatal Registered Nurse a thin NUCC code in NPPES?
Only 152 NPIs list Perinatal Registered Nurse as primary taxonomy across 37 states (peak California, 39). That is 474th 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 Perinatal Registered Nurse NPIs in Open Payments look unusual?
CMS Open Payments 2024 lists 7 paid Perinatal Registered Nurse physicians totaling $1K (16 payments; average $160, 373rd 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 Perinatal Registered Nurse NPIs, 1 appear in the Medicare Part D Prescriber PUF (average 30 claims and $372 drug cost per prescriber; 446th of 496 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
