you can bill both of those codes though when they are doing a runoff and the catheter is moved from the upper aorto to the lower and you would also bill 75625 if there was an aortogram I would appeal it for sure. You would only bill the runoff code 75635 if the catheter does not move in the aorta.
can anyone explain to my why certain insurance companies are bundling 36200 and 75716.
