You would need to contact your insurance company. Did you buy it through the company that works with IDEA or your cert organization like ACE or ACSM? That would be where to begin looking for who you bought it from and then contact them. You really should have a copy on file of your coverage. How are you going to know things like what is covered, how much does it cover, and when does it expire?
Just contact your insurer, they should be able to give it to you. You should have a hard copy of it on file also.
