Which episode of House M.D. was the show's 100th episode?

“The Greater Good” was the 100th episode of House M.D. It is the 14th episode of the show’s fifth season and centers on a patient whose choices raise questions about medical ethics and personal responsibility.

The episode originally aired in 2009. Its milestone status made it notable in the series’ production history, but it still follows the show’s standard format: House’s team examines a puzzling case while conflicts among the doctors develop alongside the medical investigation.

The title is easy to confuse with other House M.D. episode names because the series used many short, abstract titles. “The Greater Good” should also be distinguished from the season-five episode “The Social Contract,” which aired earlier in the season. Episode numbering can vary on some platforms, but official series listings identify it as episode 100.
