Definition
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.

- Classification: Pathology
- Specialization: Molecular Genetic Pathology 207ZP0007X
Choose 207ZP0007X over the general Pathology code when the provider's training or certification is specifically in molecular genetic pathology; the general code covers the classification as a whole. A provider may report more than one taxonomy code on an NPI but marks one as primary.
Medicare
CMS's taxonomy crosswalk links 207ZP0007X to Medicare specialty 22 (Physician/Pathology). That specialty — not the taxonomy code itself — is what Medicare enrollment records and uses for payment. 14,667 practitioners are enrolled under it nationally, and 15 other taxonomy codes map to the same specialty.
Other codes under the same Medicare specialty: 207ZB0001X Blood Banking & Transfusion Medicine Physician; 207ZC0006X Clinical Pathology Physician; 207ZC0008X Clinical Informatics (Pathology) Physician; 207ZC0500X Cytopathology Physician; 207ZD0900X Dermatopathology (Pathology) Physician; 207ZF0201X Forensic Pathology Physician; 207ZH0000X Hematology (Pathology) Physician; 207ZI0100X Immunopathology Physician; and 7 more.

Using 207ZP0007X
The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
