Common questions
Why is Chronic Care Clinical Nurse Specialist a thin NUCC code in NPPES?
Only 17 NPIs list Chronic Care Clinical Nurse Specialist as primary taxonomy across 12 states (peak California, 2). That is 647th 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 Chronic Care Clinical Nurse Specialist NPIs in Open Payments look unusual?
CMS Open Payments 2024 lists 2 paid Chronic Care Clinical Nurse Specialist physicians totaling $114 (3 payments; average $57, 446th 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 Chronic Care Clinical Nurse Specialist NPIs, 2 appear in the Medicare Part D Prescriber PUF (average 35 claims and $1K drug cost per prescriber; 433rd of 496 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
