Definition

A pathologist deals with the causes and nature of disease and contributes to diagnosis, prognosis and treatment through knowledge gained by the laboratory application of the biologic, chemical and physical sciences. A pathologist uses information gathered from the microscopic examination of tissue specimens, cells and body fluids, and from clinical laboratory tests on body fluids and secretions for the diagnosis, exclusion and monitoring of disease.

Where 207ZC0006X sits

Choose 207ZC0006X over the general Pathology code when the provider's training or certification is specifically in clinical 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 207ZC0006X 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; 207ZC0008X Clinical Informatics (Pathology) Physician; 207ZC0500X Cytopathology Physician; 207ZD0900X Dermatopathology (Pathology) Physician; 207ZF0201X Forensic Pathology Physician; 207ZH0000X Hematology (Pathology) Physician; 207ZI0100X Immunopathology Physician; 207ZM0300X Medical Microbiology Physician; and 7 more.

Using 207ZC0006X

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.
