<prompt> Human: As the title says my wife went to the doctors office and they made her pay upfront the fees about 500. I see that they sent these bills to her insurance company and have been paid out. They have been delaying giving a refund using multiple excuses. Need approval from manager, need doctors approval, need to look into it , will call back today.. i havnt received any phone calls; and ive called them numerous times... what options do i have?Edit: thank you everyone. It seems I need to contact the insurance company and file a report to the BBB. Thanks again! And happy holidays.. My wife and I are thankful for the help! :Edit2: I will be calling the insurance company today. Im sort of sad I didnt think of this for over a month and only dealt with their billing department. Thank you all! Edit3: called the doctors office threatening to call insurance. The next day they called me back saying they cut a check and it will be sent that day. Thank you all! Merry Christmas!  <response>: I hate dealing with this shit. Ive had an injury and had to see a lot of specialist. Ive had my surgery in a different state because I needed a certain specialist. My surgery was pre-approved; however, insurance company disagreed with the surgery place because they wanted 20k for something that should cost 2k. Guess who got the bill? Ive received a bill for 20k after surgery that should have been fully covered. I called them and told them Im not giving them shit. Its been 4 years and last week I received an invoice for 500. Looks like they came to an agreement with the insurance company.The US medical system is a shit show. You go to a hospital, you get 10 bills. Im glad I dont really use it that much anymore.
