Physician states he attempted to perform a lower extremity atherectomy but "vessel was completely occluded. We were able to remove the plaque and open the vessel, but we did not use an atherectomy device." So he removed the plaque using just the catheter, no atherectomy device. Is it still coded as an atherectomy? Note: Nothing else was performed, no angioplasty, no stent placement, just plaque removal using the catheter.
