When traveling somewhere unfamiliar, insurance is one of those things that is easy to overlook because it does not feel as exciting as planning the actual trip. Still, it can make a significant difference if something unexpected happens. I would look at medical coverage first, then check exclusions, duration, and whether the policy applies to the particular activities planned during the visit. Ukraine can require especially careful reading of the terms because different policies may treat risks differently. A useful starting point is to review general information about insurance for visitors to Ukraine and compare it with the conditions of any policy being considered.
