In House M.D., what is the name of House’s hospital department?

House’s hospital department in House M.D. is called Diagnostic Medicine.

The department specializes in solving difficult cases that other doctors have not diagnosed. Dr. Gregory House leads the unit and assembles small teams of physicians to gather evidence, test hypotheses, and revise diagnoses as new symptoms appear. This fictional department provides the show’s central workplace and its distinctive medical-mystery format.

Diagnostic medicine is a real phrase used broadly for the process of identifying disease, but a standalone department organized exactly like House’s unit is unusual. In real hospitals, complex diagnostic work is usually distributed among specialties such as internal medicine, infectious disease, neurology, radiology, pathology, and surgery.

The team’s membership changes during the series. Early members include Foreman, Cameron, and Chase, while later seasons introduce other doctors. The department is sometimes confused with House’s clinic duties, but the clinic is where he treats routine outpatient cases, often unwillingly; Diagnostic Medicine is where the rare cases are investigated.
