Thats quite smart. It seems on a 150,000$ operation they could pay the person 50,000$ to go out of country and pay for the surgery there, and still come out ahead:).
Given the smiley, you might be surprised to hear that Holland recently contracted a Thai hospital to do 200 heart surgeries on their citizens which the gov't pays for under their health care system for exactly that reason. I think we will see this happen more and more.
