In House M.D., what is the name of the hospital’s diagnostic department after House’s original team changes?

The hospital department led by Gregory House in House M.D. is the Department of Diagnostic Medicine. House’s original fellows change over the course of the series, but the department remains the formal setting for his diagnostic work and for the teams assembled around difficult cases.

The department is notable because real hospitals do not commonly organize diagnosis exactly as the show depicts it. In everyday medicine, diagnosis is distributed across primary care, internal medicine, emergency medicine, pathology, radiology, and many subspecialties. House M.D. concentrates those activities into one dramatic unit so that a small team can investigate rare and puzzling illnesses.

The department should not be confused with House’s personal specialties, nephrology and infectious disease. Those specialties describe his medical expertise, whereas diagnostic medicine describes the hospital role he leads. The distinction also separates House’s unit from the oncology department led by James Wilson and the administrative office overseen by Lisa Cuddy.
