<prompt> Human: My girlfriend and I are in the emergency room right now in network for her insurance. She had abdominal and chest pain last night and this morning. The ER doctor determined she has appendicitis and that she will have surgery tonight or possibly tomorrow morning. Is there anything we should do or know in order to minimize the size of the bill? Any tips? Sorry for the rushed post!!! Thanks everyone!!!  <response>: Make sure all staff are in-network. Sometimes the anesthesiologist or something is out of network so you get stuck with a huge bill.
