What taxonomy code 207ZP0007X means

A molecular genetic pathologist is expert in the principles, theory and technologies of molecular biology and molecular genetics. This expertise is used to make or confirm diagnoses of Mendelian genetic disorders, disorders of human development, infectious diseases and malignancies, and to assess the natural history of those disorders. A molecular genetic pathologist provides information about gene structure, function and alteration and applies laboratory techniques for diagnosis, treatment and prognosis for individuals with related disorders.

Common questions
Why is Molecular Genetic Pathology (Pathology) Physician a thin NUCC code in NPPES?
Only 169 NPIs list Molecular Genetic Pathology (Pathology) Physician as primary taxonomy across 30 states (peak California, 24). That is 464th 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 Molecular Genetic Pathology (Pathology) Physician NPIs in Open Payments look unusual?
CMS Open Payments 2024 lists 26 paid Molecular Genetic Pathology (Pathology) Physician physicians totaling $92K (99 payments; average $4K, 120th 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 Molecular Genetic Pathology (Pathology) Physician NPIs, 2 appear in the Medicare Part D Prescriber PUF (average 13 claims and $230 drug cost per prescriber; 489th of 496 specialties by average claims). Non-prescribing clinicians in the same NUCC code are still in NPPES.
