In House M.D., which specialty does Dr. House lead at Princeton-Plainsboro Teaching Hospital?

Dr. House leads the Department of Diagnostic Medicine at Princeton-Plainsboro Teaching Hospital in House M.D.

The department handles patients whose symptoms do not fit an obvious diagnosis or whose cases have resisted conventional treatment. House assembles a small team of fellows to generate hypotheses, order tests, and challenge one another’s interpretations. This structure gives the series a mystery format built around medical reasoning.

Diagnostic medicine is distinct from a single organ-based specialty such as cardiology or neurosurgery. It draws on knowledge from many fields and requires doctors to connect symptoms across body systems. House’s team frequently consults specialists when a case points toward surgery, infectious disease, neurology, or another discipline.

The specialty is central to the program’s title and premise, but House is not portrayed as a general practitioner. His department’s unusual cases and his unconventional methods distinguish him from the hospital’s other medical divisions.
