About 33507: Intramural anomalous coronary artery repair
Surgical correction of an anomalous coronary artery with an intramural course, reported when the operative findings and repair support that anatomy.
Code 33507 describes operative correction of an anomalous coronary artery when part of the vessel runs within the aortic wall. A cardiac surgeon typically exposes the coronary origin through an aortotomy and opens the shared wall to establish a more direct coronary channel. The operation is generally performed in a hospital operating room for congenital coronary anatomy that may be investigated because of symptoms, ischemia, or other risk findings.
Choose the code based on the documented intramural course and repair performed, not solely on the diagnosis of an anomalous coronary origin. The operative report should identify the affected artery, its course, and the corrective work. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
