We are receiving a denial from a payor when we bill 64448 Femoral Nerve, continous infusion by catheter with a 01320 Anesthesia code for surgery on the knee. This patient had a knee arthroscopy with acl resconstruction. I know these two codes hit the CCI edits but how do I know if I can apply modifier 59? They perform the femoral nerve injection prior to the anesthesia underal general sedation. Thanks for any advice.
