Well, after talking with my medicare rep today I found out that Scubaman is correct. Medicare will cover me in any emergency up to 80% and my supplemental will cover the other 20%. She said it would not cover something that is prearranged. Example: You go to SXM for some treatment that is not offered in the US, or anything planned ahead of time, no coverage. It will cover any emergency with a 250 deductible first. I gave her some examples. I have a heart attack, I will be covered. It doesn't cover transportation back home or anything like that. I break a leg, get cut and need stitches etc. All covered. I'm learning something new everyday.
