Ask Dr. Z

During aortic valve replacement (33405), a questionable fistula was repaired. Physician notes the significant aorta to the pulmonary artery defect was repaired by direct technique (suture repair). Would this be reported, and what CPT code would be used? Code 33500 does not seem correct since it was noted as questionable and appears to be an incidental finding. Also, aortic root abscess was noted, and debridement of the aortic valve and root abscess was completed with closure. Would this be included in code 33405 since it was necessary to complete the valve replacement?
