Given the extremely high price
of health insurance in the US you'd be better off to get health insurance for any other country and rely on getting there from wherever you are in the world, not the US.
I once bought health insurance from Travel Underwriters, Worldwide Mediclaim. When I made a claim they simply refused to pay, because I didn't have a credit card for them to put my expenses on( and force me to go to court to get reimbursement.) Other I've met have had bad experiences with this company.
Consumer reports say Voyager is one of the best.
People are flying overseas for medical attention a fraction the price
of the same operation in the US, and often more reliable results .
I saw a report that said 40% of medical diagnosises in the US are wrong. When doctors went on strike in LA in the 70's the death rate declined noticably. Both Spain
spend a fraction the amount per capita on health care
yet have longer life expectancies.
I don't know why yanks in other countries with better medical systems feel the need to go to one of the worst countries in the world for medical atention.
