IMDb certainly isn't always right. However, uncredited actors can appear though. In the episode Bad Blood, there's this patient who needs blood after (I believe it was) a car accident, but his family won't allow it. (You know the episode of course) The actor wasn't credited, though he frequently appears in the episode, despite having no lines because of being in coma.
