Millions of tourists travel oversees every year. Traveling abroad can be exciting and educational, but for some, the experience can turn into a disaster if a medical emergency or health issue arises. Health care treatment abroad is often extremely expensive and many foreign countries do not accept U.S. health insurance. Depending upon the area you are visiting and the policies of that country, you may be denied health care if you are unable to provide valid travel medical insurance or cash payment. Basic medical expenses, hospital rates and evacuation back to the United States can all add up to thousands of dollars.
