What was House’s medical department called in House, M.D.?

House’s medical department in House, M.D. was the Department of Diagnostic Medicine.

Gregory House leads a small team there, taking on patients whose symptoms are unusual, conflicting, or unexplained by more routine diagnoses. The department’s work drives the show’s central premise: doctors test hypotheses, challenge one another, and revise their conclusions as new evidence appears.

The department is fictionalized for television, but its concept draws on real diagnostic practice. In actual hospitals, complex cases can involve specialists from internal medicine, infectious disease, neurology, rheumatology, and other fields rather than one permanent team working under a single “diagnostic medicine” banner.

The name is often shortened in dialogue to “diagnostics.” It should not be confused with House’s personal medical training or with a department such as pathology. The show presents House as a physician specializing in diagnosis, while his hospital department coordinates the difficult cases.
