Specialties & License Numbers Reported to NPPES

Self-certified to NPPES: 2024-11-05
Pathology - Anatomic Pathology & Clinical Pathology Primary Specialty

NUCC Taxonomy Code: 207ZP0102X

License # reported to NPPES CA A78518

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.

Pathology - Cytopathology

NUCC Taxonomy Code: 207ZC0500X

License # reported to NPPES CA A78518

A cytopathologist is an anatomic pathologist trained in the diagnosis of human disease by means of the study of cells obtained from body secretions and fluids, by scraping, washing, or sponging the surface of a lesion, or by the aspiration of a tumor mass or body organ with a fine needle. A major aspect of a cytopathologist's practice is the interpretation of Papanicolaou-stained smears of cells from the female reproductive systems, the "Pap" test. However, the cytopathologist's expertise is applied to the diagnosis of cells from all systems and areas of the body. He/she is a consultant to all medical specialists.
