Article Summary A Growing Number of U.S. Citizens Are Going to Other

Article Summary
A growing number of U.S. citizens are going to other countries for elective surgery procedures. Improved quality and significant cost savings abroad have attracted an increasing number of what are being referred to as American medical tourists, especially those who either do not have insurance or whose insurance does not cover the desired procedure. As few as five years ago, Americans tended to travel to countries such as Thailand or Mexico for the procedures, but many are now choosing to go to Europe, where governments and hospitals are now publicizing these services. Many of the procedures being done overseas are joint replacement, and partly in response to the number of patients going abroad for these procedures, programs are being developed to reduce the cost of these surgeries in the United States.
