What 33507 covers

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.

33500Coronary fistula repair
33500 addresses repair of a coronary arteriovenous fistula, a connection between vessels. Code 33507 concerns correction of an anomalous coronary artery with an intramural course.

33507 billing questions

What distinguishes 33507 from other anomalous coronary artery repairs?

The defining feature is a documented intramural course, with the repair directed at that segment. Other repair approaches are selected according to the anatomy and operation performed.

Can modifier 50 be used for repair of both coronary arteries?

No. CMS identifies bilateral adjustment as inappropriate for this code.

How does the 90-day global period affect postoperative billing?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period.

Can an assistant surgeon or co-surgeon be reported?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

How is 33507 affected when other procedures are performed in the same session?

The highest-valued procedure is paid in full, and the other procedures are subject to the standard multiple-procedure reduction.
