Good question.
Do you need travel insurance?
How good is your health insurance at home, what credit cards do you carry and the infamous question…how good is your credit???
Or do you have access to $100,000 international cash with 24 hours notice.
Sooo… what if I have a heart attack while phucking some girl in LOS

… believe it or not, I have thought about this while spending time at the gym sweating on the elliptical machine

…what would happen to me ?
So, I asked my health insurance agent (I have a policy with Blue Cross CA), and… I would be covered… and my automatic Visa card travel insurance (most cards have some type) will cover most deductibles, medical and auto, if I used it to pay for the plane ticket, car rental and/or hotel… peace of mind…well sort of.
The reality is that when you check out of a hospital in most foreign countries they want cash, travelers check, or credit card… no such thing as billing your insurance company or yourself… you will get reimbursed by whomever/whatever, but they want to be paid before you leave the country. If you buy a policy, make sure it will provide instant payment to a foreign hospital or yourself. If you plan to use your current coverage (like me), make sure your cc limit (with a call or two) will cover your hospital bill and get you home.
