Patients who travel to another country to seek health care are referred to as medical tourists. The term arose because many Americans seek less expensive elective surgical, dental, or cosmetic procedures while vacationing abroad.1 Of course, US hospitals and physicians have also long cared for medical tourists from other countries. Now, many medical tourists are going the other way—from the United States to other countries to receive health care. In 2007, it is estimated that 750,000 Americans traveled to other countries for health care.
