Emergency Medical Backing gives insurance and medical assistance for travelers. It would protect you if you had to be airlifted off a mountain because of a skiing or hiking accident, or if you had to stay for a extended period of time in a foreign hospital. Insurers would also provide insurance cover if you got critically sick or were injured and had to be flown home. Various commercial airlines require exceptionally sick passengers to ride on a stretcher with a doctor. Usually this means that you might have to pay for 10 or more seats on a plane at a probable pot cost of over $10,000.
Prior to purchasing this kind of coverage, confirm with your individual health insurance carrier. Find out what type of coverage you have when traveling in a foreign country and if there are any confines. Also, request if the policy will compensate to fly you home or to a country with first-rate medical care.
