Just one of the many reasons my wife and I stick with traditional Medicare.
I personally have a Fed VP Blue Cross/Blue Shield for life and Medicare.
I travel the world and Medicare is not for out of the country. So my BXBS plan is the same one the diplomats have in the foreign embassies. I once had to show that I had $100K in coverage to travel in a foreign country and asked them for a certificate. They laughed at me and said it is unlimited, thanks to the Department of Defense.
I have two friends who just moved here from Cuba. Young and hard working couple, but what a surprise as their food, housing and medical care was free there, just wait in line.
