I think that NZ might see some increase of people from out of the country, but I don't think it's going to be anything drastic.

Most Americans would still opt for surgery in the U.S., since those that have at least some kind of insurance, however minimal it be, would find it less expensive than a trip out of the country. And what about follow-up after the surgery, physical therapy, etc. And what happens when she comes home if there are complications? Does she have to go back to NZ?? Most U.S. doctors won't get involved with another doctor's patient if there is a problem. Believe me - my brother is going thru this right now. Botched surgery and another doctor won't see him and get involved. Must be some unwritten code between doctors - protect each other and screw the patient!

And as for those who have no insurance - well they couldn't afford to go outside the U.S. anyway if they couldn't afford insurance in the first place.
