What taxonomy code 207ZC0500X means
207ZC0500X is the National Uniform Claim Committee code for Pathology, Cytopathology, in the grouping Allopathic & Osteopathic Physicians. 551 NPPES records list it as their primary taxonomy (file of Aug 9, 2026).
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.
