Medical Specialties & State Licenses

CMS Verified: 2025-06-17

Pathology - Anatomic Pathology & Clinical Pathology Primary Specialty

NUCC Taxonomy Code: 207ZP0102X

State License CA A124424

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 - Clinical Informatics

NUCC Taxonomy Code: 207ZC0008X

State License CA S-21-444

Physicians who practice Clinical Informatics collaborate with other health care and information technology professionals to analyze, design, implement and evaluate information and communication systems that enhance individual and population health outcomes, improve patient care, and strengthen the clinician-patient relationship. Clinical Informaticians use their knowledge of patient care combined with their understanding of informatics concepts, methods, and tools to: assess information and knowledge needs of health care professionals and patients; characterize, evaluate, and refine clinical processes; develop, implement, and refine clinical decision support systems; and lead or participate in the procurement, customization, development, implementation, management, evaluation, and continuous improvement of clinical information systems.

Pathology - Hematology

NUCC Taxonomy Code: 207ZH0000X

State License CA S-16-377

A hematopathologist is expert in diseases that affect blood cells, blood clotting mechanisms, bone marrow and lymph nodes. This physician has the knowledge and technical skills essential for the laboratory diagnosis of anemias, leukemias, lymphomas, bleeding disorders and blood clotting disorders.

Pathology - Molecular Genetic Pathology

NUCC Taxonomy Code: 207ZP0007X

State License CA S-17-427

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.
