Frequently Asked Questions

Why is Obesity Medicine (Internal Medicine) Physician a thin NUCC code in NPPES?
Only 150 NPIs list Obesity Medicine (Internal Medicine) Physician as primary taxonomy across 38 states (peak California, 23). That is 487th of 690 NUCC codes by headcount. Thin codes are still searchable by NPI; do not treat the low count as a quality signal.
Do the few Obesity Medicine (Internal Medicine) Physician NPIs in Open Payments look unusual?
CMS Open Payments 2024 lists 88 paid Obesity Medicine (Internal Medicine) Physician physicians totaling $459K (1,778 payments; average $5K, 88th of 551 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 Obesity Medicine (Internal Medicine) Physician NPIs, 117 appear in the Medicare Part D Prescriber PUF (average 1,026 claims and $243K drug cost per prescriber; 143rd of 572 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
