I work in a hospital setting and every Arterial Duplex (93924) that comes in we do an ABI (93923) with the Duplex. The facility is telling me that we are unable to bill these together but there are no CCI edits with this. Can someone with vascular experience tell me if we can in fact bill these two codes together or should we only be billing the Arterial (93924). I truly appreciate the help and time with this as we have been going around in circles and I would really like to know how other facilities are doing it. Thank you so much.
