PS read the fine print very carefully. When they say it covers evacuation, it often means the ambulance service, and most commonly to the nearest capable hospital, wherever you are. What I think most people are wanting is covering your movement (once stabilized) to the hospital of your choice, that is, back home.
With Medjet you are definitely covered. I've purchased much less expensive policies with primary medical coverage and evacuation coverage for around $75 or less per trip. These are from squaremouth.com; I put down $0 for the trip coverage so I'm just paying for medical & evac. Note that unless you insure the full non-refundable value of your trip policies have a prior condition lookback.
Here are what policies can say (you need to check the one you are considering, some don't say they'll bring you back to the US)
Emergency Evacuation – means:
c) Transportation to the adequate licensed medical facility nearest Your home to obtain further medical treatment or to recover, after being treated at a local licensed medical facility, and the onsite attending Physician determines that the Insured is medically able to be transported; or If the Emergency Evacuation Upgrade is selected and the appropriate cost has been paid, the following will also apply:
d) Transportation from an adequate licensed medical facility to an adequate licensed medical facility of Your choice for further treatment if the onsite attending Physician certifies that the Insured is medically able to travel.
I'm not an insurance agent or lawyer, but clause (c) to me seems like it will get me home
