<prompt> Human: I have next to no experience with medical bills, as Ive never had to pay for anything more serious than a trip to the dermatologist. Here I am pregnant, and trying to figure out insurance and billing for the first time. Believe me: pregnancy hormones and unexpected medical bills make a great combination. sI went a couple of weeks ago for my 20 week anatomy scan. All standard, no complications. So far, all of my precious doctors visits and earlier ultrasounds were paid for, no problem. But yesterday I got an Explanation of Benefits from my insurance saying that they werent paying for 485 of the ultrasound that the doc billed them for. Called today for an explanation and they said that, in addition to the normal ultrasound, the doctor had submitted bills to them for 2 Doppler procedures to check fetal blood flow and a duplex scan for arterial invenous outflow. They say these procedures are elective, so they wont pay.The doctors office is already closed, so Ill definitely be following up with them tomorrow, but my question is this: is it normalethical for a doctor to fold elective procedures into a normal, routine exam? Do I have a leg to stand on if I call the doc and say I dont think I should have to pay for procedures I didnt authorize? After some googling, it looks like lots of insurance providers wont cover these scans if all of the other heart scans look normal, so its not just a question of my insurance being weirdstingy well, Im sure thats part of it, but ya know...insurancePlease advise, and tell me what you more experienced Redditors do when faced with surprise medical bills!  <response>: Call the doctor and have them resubmit to your insurance as medically necessary. That should take care of it. If they cant do that you may need to appeal it directly with insurance, in which case you should get a letter from your doctor explaining why he thought the procedures were medically necessary and submit that with the appeal
