dude, it usually cost 30-50 thousand nepali rupees. there are hundreds of such insurance provider in nepal these days, just talk to the agent that you got ticket of your parents from and he will bring it to you in no time!

I decided not to take that insurance when my parents visited me. when i investigated, i found:

1. my dad is diabetic - if anything happened as a side effect or directly related to diabetese....the insurance doesn't cover.

2. if my dad cut his fingure, usually diabetic takes long time to stop bleeding....blood lose because of long time bleeding...it will not be covered since it is the effect of being diabetic....meaning only the handiplaster will be covered.

3. my mom has high blood pressure....none of the event caused by high blood pressure will be covered....

i hope you understood.

but there are some other insurance company that will charge you hell lot of money, dont even think about it if you are not a millianaire in US,  that will cover everything.
