What 33513 covers

Code 33513 describes coronary artery bypass surgery using venous conduits to bypass four coronary targets. A cardiothoracic surgeon typically performs the operation in a hospital operating room, often using segments of the patient’s saphenous vein to route blood around obstructed coronary arteries. The operative report should identify the conduit type and the distal coronary targets; sequential grafting may require attention to the number of distal anastomoses rather than simply the number of harvested vein segments.

Select this code when the bypasses are venous-only. If arterial and venous conduits are both used, the arterial bypass code and the applicable venous add-on code describe that combination instead. Endoscopic vein harvesting may be reported separately with 33508 when performed and supported by the operative record. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate; an assistant at surgery may be paid, but co-surgeons and team surgery are not permitted.
