Michelle, good for you keeping those medical bills in one place. Do you use Excel (Microsoft spreadsheet)? I would strongly recommend setting up a file for this stuff, because you're going to need it. These places parse out the charges like no one else on earth, and you'll need to keep track of every time the insurance company pays a bill, because if your hospital is anything like the ones I dealt with, the right hand doesn't always know what the left hand is doing. You may need to call them occasionally and say "Per the insurance payment on X date, the bill you're charging me for again has already been paid."
Alas, I know this from personal experience. It takes a while to sort it out.
It's a couple of regular work days here, catching up on stuff for work. I'll go back and forth between the office (finishing scanning) and the sun room next door, putting more stuff away in there, finishing the push I started a couple of weeks ago.
