Common questions

Why is Perinatal Nurse Practitioner a thin NUCC code in NPPES?

Only 71 NPIs list Perinatal Nurse Practitioner as primary taxonomy across 18 states (peak Colorado, 13). That is 547th 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 Nurse Practitioner NPIs in Open Payments look unusual?

CMS Open Payments 2024 lists 13 paid Perinatal Nurse Practitioner physicians totaling $2K (61 payments; average $160, 372nd 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 Nurse Practitioner NPIs, 11 appear in the Medicare Part D Prescriber PUF (average 55 claims and $5K drug cost per prescriber; 407th of 496 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
