What is required?
Participants in global medical outreach teams with Power of a Nickel are required to have medical evacuation insurance. The cost is very reasonable when traveling with a non-profit organization. Evacuation costs rarely are less than $100,000 and typically much more depending on the location the evacuation is needed - thus the requirement for insurance.
If you are not familiar with international evacuation insurance, a good resource is Square Mouth which allows you to choose from many carriers from one easy website.
What is suggested?
You may also want to consider trip cancellation insurance that will cover your trip costs should you need to cancel your trip. That information is available at www.squaremouth.com and can be purchased at the same time as the evacuation insurance. This is not required - but we would suggest you consider its purchase to avoid loss of funds should a reason arise that would require you to cancel from the trip.
