Insurance question

TinaL99

I have received all of my bills from when I had Audrey (I hope!).  According to my employee benefits handbook, my copay for delivery is $500, newborn nursery care is covered in full and prenatal/postpartum care is also covered in full.  My bill is for $1,345.  I obviously have questions about this.  Do I call my insurance company, my benefits advisor, or the hospital?
