House M.D. broadcast 177 episodes over its complete original run. The series aired eight seasons from 2004 through 2012.
Its episodes generally follow a medical-mystery structure: a patient develops puzzling symptoms, House’s team proposes and tests diagnoses, and new evidence forces them to revise their theories. Continuing storylines about House, Wilson, Cuddy, and the diagnostic fellows run alongside those weekly cases.
The episode total includes the complete regular series, from the pilot through the finale, “Everybody Dies.” It does not refer to a count of only the episodes in which every member of the original team appears, since the team changed substantially during the show’s run.
Episode counts can vary on websites when specials, recaps, or promotional programs are included. The standard series total for House M.D. is 177 broadcast episodes.
