What was Dr. House’s official department at Princeton-Plainsboro in House M.D.?

Dr. House’s official department at Princeton-Plainsboro in House M.D. was Diagnostic Medicine.

House led a small team that handled unusual cases other departments could not solve. The department’s work involved generating and testing competing explanations for a patient’s symptoms, often by combining information from multiple specialties.

Diagnostic Medicine is central to the show’s premise because House is portrayed less as a routine clinic physician and more as a medical detective. His team might investigate infectious disease, neurology, immunology, toxicology, or other areas when a case demanded it.

The department is fictionalized for dramatic storytelling, and its exact structure changes over the course of the series. It should not be confused with the hospital’s outpatient clinic, where House was repeatedly assigned patient-care duties. The diagnostic department is the specific professional unit associated with House’s case-solving team.
