What is the title of House M.D.’s 100th episode?

House M.D.’s 100th episode is titled “The Greater Good.”

The episode is the 14th installment of the show’s fifth season and originally aired in 2009. It follows the diagnostic team as they investigate a woman whose symptoms develop after she leaves a convent, while the hospital’s doctors confront questions about personal sacrifice and medical responsibility.

“The Greater Good” is notable because it marks the series’ 100-episode milestone, a significant broadcast achievement for a scripted television drama. The title refers to the ethical tension at the center of the story rather than to a medical procedure or diagnosis.

It is sometimes confused with other House M.D. episodes from the same season, including “The Social Contract,” “Locked In,” and “Birthmarks.” Episode numbering can also vary in unofficial lists when specials or production-order listings are included, but “The Greater Good” is identified as the show’s 100th aired episode.
