First of all, the thought of doctors competing on price kind of scares me. Doctor A says he can treat your heart disease for 10k, doctor B says he will treat it for 5k. Are they both doing the same thing? Is doctor B using cost cutting methods that are potentially harmful?

Along the same lines, would there be low cost providers and luxury providers kind of like the airlines? That's cool for airlines, because air travel is not a necessity. But medical care isn't something that should be segmented based on quality.

Finally given the fact that most medical usage is spontaneous, people aren't going to be shopping around for the best prices like they would for a TV. You are going to go to the hospital, do whatever procedures the doctor thinks is best, and pay the cost.
