About Pathology Providers

A pathologist is a medical doctor who specializes in diagnosing diseases by analyzing laboratory samples of cells, tissues, and bodily fluids. They examine biopsies under microscopes, interpret laboratory tests, and perform autopsies, providing diagnostic reports to oncology and surgery teams. Pathologists earn an MD or DO degree, complete a four-year residency in pathology, and pass board certification exams. They play a quiet but critical role in medicine, identifying cancers, infections, and genetic disorders to guide patient treatment.

Locating a pathologist's NPI number is necessary for laboratory billing, hospital diagnostic claims, and insurance processing. Pathological evaluations are billed as diagnostic services, requiring the pathologist's NPI as the rendering provider on claims. The NPI registry confirms the physician's licensing, board certification, and pathology taxonomy classification. Checking the NPI registry helps clinical laboratories audit billing compliance, verify physician credentials, and prevent insurance claim delays for diagnostic tests.
