I'm not sure what else you can do on the insurance company's end, but maybe contact the hospital and ask to speak to a patien liasion? That is what I was told to do. (I still have to make the call)
DS was placed in the NICU 24 hours after being born because he was spitting up old blood (it was mine, not his) and they almost sent him to the children's hospital. Once they figured out what was wrong the doctor said he could come back to
my room as soon as he was done with his IV. Well, they charged us for the NICU from the time he went over there until we went home. So I'm fighting it. The NICU was 4200/day and the regular nursery was 820/day. I have to pay
10%, and even then that's a significant difference!
