I am insured with AllClear ...annual world wide cover, EVERY time I have a procedure or a check up I inform them. My cover worldwide was never cheap (I have five pages of medical conditions !) cost me just under £2,000 as I travel to the U S , Canada, Mexico, Panama, the Antarctic, Alaska, Norway etc etc etc ...plus going around Europe, France and Menorca (where I used to live), lots of other European countries ........they have an extremely comprehensive list of requirements ....I said last time if I die abroad, just throw me overboard (often go on cruises solo) ...they said they cant do that (probably pollute the ocean ! ) ......Now that I am approaching 77 in a couple of weeks, going further afield until my Ins runs out in February, I am having to think about renewing it, and how much extra it is going to be ! I do know if I cut out the U S it would be cheaper ....did ask Stay Sure for a quote, but they say they cannot quote until 30 days before my current insurance runs out !!!! ...seems a bit odd ! but make sure you identify EVERY problem as whoever you insure with will, if they can, find a reason NOT to pay (my husband was an Insurance broker with Lloyds of London ....actually used to laugh and boast about how many claims were not met ....a lady on here said once her husband DIED just before they were going on a cruise ...after many months, medical letters, etc the company REFUSED to pay for the cancelled cruise and made some ridiculous stated reason as ;he had toothache aged 10 !) (not exactly what was said, but she said it was like that !!! the Ombudsman did manage to get a small payment from them ....but paying insurance you shouldn't have to do that !
