Common questions
Why is Pain Management Registered Nurse a thin NUCC code in NPPES?
Only 144 NPIs list Pain Management Registered Nurse as primary taxonomy across 42 states (peak California, 15). That is 483rd 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 Pain Management Registered Nurse NPIs in Open Payments look unusual?
CMS Open Payments 2024 lists 8 paid Pain Management Registered Nurse physicians totaling $2K (126 payments; average $299, 332nd 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 Pain Management Registered Nurse NPIs, 9 appear in the Medicare Part D Prescriber PUF (average 2,528 claims and $162K drug cost per prescriber; 25th of 496 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
