It certainly seems like he's an INTP...
Introvert--he likes to bounce ideas off of other people, but ultimately he needs large amounts of time alone. He's afraid of forming close relationships with other people (besides with Wilson, and that's one of the most dysfunctional--albeit entertaining--relationships I've ever seen.) He doesn't like to express his emotions, even with his closest friends, and uses humor as a defense mechanism (although the show would probably suck if he didn't.) The misanthropy hints at introversion, as well (although obviously all introverts are not misanthropists) and although he is not afraid to interrupt others, if someone interrupts him while he's "busy" thinking in his office he gets extremely annoyed.
Intuitive--he is able to see the whole before he sees the parts. For example, in episodes (such as the the one where he kidnaps the actor and the one where he gets a migraine and takes a bunch of acid) he realizes the diagnosis before he even knows the cause. He is able to put seemingly unrelated bits of information together to find a solution--he quickly brushes aside details that aren't important and is able to use his intuition to find an answer even when there isn't decisive proof (such as the poker episode where he realizes six year old Ian has one of the rarest diseases in the country, while everyone else assumes it's dehydration.)
Thinking--this doesn't need much of an explanation because it's so obvious. He's obsessed with truth--doesn't like emotional displays of affection--only concerned with what can be rationally quantified.
Perceiving--he arrives compulsively late every day. He refuses to work hard: he will only put all of his efforts into a case if he finds it interesting--and if he finds it interesting, it isn't work. He doesn't care what other people think of him, showing up to work each day in sneakers and jeans. It is true that he is an excellent planner and manipulator (kind of a Machiavellian type of style) and so he would appear to be an INTJ strategist--but this is really all just a mind game for him, and he usually doesn't gain anything out of his manipulation of others. Although he sometimes offers vague reasons for the games he plays with people (conflict breeds creativity!), at the end of the day he really does just like to screw with people.
So....to answer your actual question...yes. He kind of does represent the "screwed up" INTP. Although, on the other hand, is he really screwed up? Sure, he's a manipulative, anti-social narcissist--but he's also a brilliant doctor who has saved hundreds of lives, which is more than a lot of INTPs (or a lot of people) can truly say about their lives. So, who knows? I, personally, like House quite a lot, although I wouldn't want to be him.
And now, an elephant.
