Watched a CBC Marketplace show last night about travel medical insurance. Apparently, to interpret the application questionnaire, you need both a medical and a legal degree!
I found it both interesting and somewhat cautionary - as with most insurance policies, it's only when you make a claim that you discover you don't have the coverage you thought you'd purchased. The show featured a guy who's heart attack/treatment costs claim (some $360,000+) was denied due to some inadvertent misinformation he provided regarding diverticular disease and gasto-intestinal bleeding!!!
