Most of the travel accident plans I looked at were United healthcare. Usually travel accident plans (not evacuation insurance) are under $50. It would be for a situation like yours. I’ve never tried to call my health insurance to see if I could add a short term travel accident policy. The plans that are advertised are too easy to sign up and buy, just select dates, coverage, and country and some personal information done in 5 minutes. Seems health care almost everywhere outside the US is very affordable though. I question if it’s really necessary but I like the peace of mind combined with medical evacuation insurance.
