76830 is the "procedure" code. it sounds like it's the diagnosis code that you need changed? First, the insurance company most likely did not tell you to have physician "change" the code, they can't do that, it's illegal. They are not even supposed to give coding advice. This is between the doctor and the documentation he/she has for the visit. If your plan does not cover the procedure for that diagnosis, the doctor cannot arbitrarily change the code to have it paid for. the 76830 is for a trans vaginal ultrasound which sounds right, so again, I'm guessing the problem is with their "diagnosis code" They also might be denying it as being included with the placement? Not sure but if you could read the exact denial from your EOB that might help us.
