Paying bills

It is a 5 am and I can't sleep so I decided to pay bills.  We have enough to pay all of our bills which I am thankful for. Is it bad that I am ignoring the medical bills?  I kind of find that if I ignore them, they tend to change.  Insurance will pay it or something.....so they are sitting here.  It isn't like the total is that bad but I don't want to give them a dime that they don't need.
