Insurance forum

Since there are all kinds of health insurance available in the US there are all kinds of answers to your question. My state provided health insurance definitely didn't cover me while abroad, but it sounds like you have some serious private health care, and if they send you a letter with their letterhead confirming that you will be covered in SE Asia then, well, that would be good enough for me.

If you want to get down to the nitty gritty ask them to send you the complete terms and conditions of your policy, read it over, and call or write them about whatever you find to be lacking in regards to your specific travel plans... Unless you record them actually saying they'll cover a certain type of accident, they may not be obliged to do so if your plan doesn't specifically cover it as it's written. A lot of travel insurance doesn't even cover motorbiking accidents at all so if they're willing to tell you over the phone they'll cover that then you might ask them to write specifically that they will cover that in specific countries (or "any" country abroad). If they agree to that then it's as good as gold. Also bear in mind that if you don't have a motorcycle license in the US that could make a difference as to whether or not they cover a motorcycling accident abroad.

I called my insurance company, covered for any emergancy. I also have some coverage with the credit card that the flight was booked on, but really it isn't much coverage. I am now looking at travel insurance too.
