You might be on your own anyway. Evacuation might mean taking you to the nearest "acceptable" facility. My friend's brother had a transient ischemic attack on a Caribbean cruise and was taken to St. Kitts, where the hospital gave him a bed and 3 squares a day. No PT, no TV, no Wi-Fi. Friend went down there and brought him home- he needed a wheel chair and had temporarily lost his ability to read so could not have made it home on his own.
I've gotten coverage from MedJet Assist for my more adventurous trips- they're a class act and they'll take you in a private plane to any hospital you choose, including back home. The catch is that you have to have been admitted to a hospital at the place where you're traveling. So, "treated and released", which applies to most COVID cases (thank heaven) wouldn't qualify.
