Can I use my health insurance overseas?

I’ll be travelling soon and I want to make sure that I have everything ready including my emergency plans. I have a health insurance that I pay religiously every month. I don’t know though if I can use this abroad. I’ll be visiting Thailand for leisure and probably meet some Thai ladies too. But before I could enjoy my trip, I still want to ensure that I can count on my insurance in case I get into an accident or get sick while in Thailand. Does anyone have any idea about this? Has anyone tried using their health insurance overseas?
