Sure you can call your insurer... just get the name (they'll probably only give you a 1st name.) Write down the date, the time you spoke with the representative, & the name they give you, as well as what they told you. Realistically though, there may be no way to be absolutely 100% positive the insurance company will pay. Someone higher up the food chain, at the insurance company, could look at the claim & decide it's not valid for some reason. Most insurance companies say that they will not guarantee payment until they receive, & come to a decision with regard to, the bill. At least this has been my experience.
