Trip protection insurance or Travel medical insurance?

Trip Protection Insurance

Trip insurance plans are designed to insure both the health of the traveler as well as the cost of non-refundable trip expenses should the trip get cancelled or is interrupted. The trip interruption insurance coverage is effective after the trip has begun but is interrupted due to an emergency.
The non-refundable expenses can include hotel rooms, airline and cruise tickets...Depending on the trip insurance plan, it might cover unexpected expenses resulting from lost, damaged, delayed or stolen luggage. While some plans require that the trip is cancelled for an approved reason other plans are available with 'cancel for any reason' benefit. Unless you have purchased 'cancel for any reason' policy, there are many valid reasons to change the dates of trip or cancel it completely that will not be covered.
Trip insurance are popular with US citizens vacationing outside the United States. This is understandable given the domestic US health insurance provides little to no coverage outside the US and does not insure the costs of the vacation itself.

Travel Health Insurance

These plans mainly insure the traveler in the event of any unexpected sickness or accident while traveling outside one's home country. These plans work like regular health insurance but with the limitations of having no coverage for preventive care and with only some plans offering limited coverage for pre-existing conditions.
The coverage includes both inpatient and outpatient care, evacuation and repatriation. Travel insurance covers the hospital room and board, ambulance services and any emergency services. Depending on the policy it might also cover political evacuation, terrorism, accidental death and dismemberment, natural disaster and repatriation of remains. Travel medical insurance is popular with international travellers visiting countries with high costs of healthcare like the United States or Europe. Immigrant communities in the US who have family visiting them buy travel medical insurance to ensure that parents or other family members do not have to worry about medical expenses while in the US.
