What medical specialty did Gregory House and his team lead in House M.D.?

Gregory House and his team lead the Department of Diagnostic Medicine in House M.D. The specialty focuses on identifying the causes of difficult or unexplained illnesses, often after conventional approaches have failed.

The department gives the series its distinctive structure. Each week, House’s team gathers symptoms, reviews medical histories, orders tests, and proposes diagnoses. They repeatedly revise their theories when new evidence appears or when a treatment produces an unexpected result.

Diagnostic medicine is a real area of clinical practice, although the show dramatizes it by presenting unusually rare cases and giving one small team responsibility for an extraordinary range of conditions. In real hospitals, diagnosis is generally shared across specialties rather than handled exactly as shown.

House’s team members bring different expertise to the department. Their disagreements are important because the show treats diagnosis as collaborative reasoning, even though House often dominates the process. The department’s name also distinguishes House from colleagues such as Wilson in oncology and Foreman in neurology.
