<prompt> Human: Not sure if this is where I should be posting, but Im presently in tears and not sure how to handle this. I received a letter from my insurance company for a denied claim for 7500 for an out-of-network physician assistant who was present at my surgery 5 months ago. She didnt submit the claim until 2 weeks ago, and this is the first Im hearing about it. Ive already paid out 6000 for this surgery and continue to pay 200mo for a surprise bill for the anesthesiologist. Should I try and haggle the bill? Should I try and fight it? This wasnt an emergency surgery, it was scheduled. The doctor and the hospital sat down with me prior to the surgery and negotiated a price and I paid it. This PA is asking for more than 6X what I paid the doctor who did the surgery. Can anyone really just scrub in and then charge me for it while Im not awake? Shouldnt they have notified me that I needed an anesthesiologist and a PA prior to this so I could find an in-network one? Or perhaps at least tried to find an in-network PA? I felt terrible when I got the surprise 1700 anesthesiology bill, but now Im at a point of utter upset with the 7500 one. I feel completely taken advantage of by the people I trusted to take care of me.I have enough savings to cover the bill but it will tap me out. Im currently an unemployed full-time student living on my savings from my last job of 10 years and will be graduating in 3 semesters. I live in NY if that makes any sort of difference. Tomorrow I am going to try and get copies of the paperwork I signed at the hospital prior to the surgery.EDIT: Thank you all for your responses. After checking the codes I was billed for, it appears that the PA is billing me with 2 of the same codes that the doctor used for the surgery. The third code is for a bogus procedure removal of an organ which never was actually performed. This could just be an error, or possibly fraud on the PAs part. Im going to wait and see if I receive a bill. There is also a phone number that the insurance company provided me with to report suspected fraud so I will get in touch with them in the case that this particular PA does this type of illegitimate claim submission often. Thank you all for your help. I feel so relieved, and can get back to focusing on my final this week.  <response>: Something similar happened to me. I had surgery and even though my doctor was in-network, the surgery center was not. I called my insurance company and told them that I had not been informed that the surgery center was out-of-network and that I felt I shouldnt have to pay. They said theyd look into it and get back to me. I never heard anything officially or got a bill but the charge disappeared from my EOB statement a few months later. It could be as simple as a phone call.
