About 33320: Major vessel repair with bypass
Report this code when a surgeon repairs a major cardiovascular vessel during an operation performed with cardiopulmonary bypass.
This code describes operative repair of a major blood vessel, such as the aorta or pulmonary artery, when cardiopulmonary bypass is used. Cardiothoracic surgeons typically perform the service in a hospital operating room. The operative report should identify the vessel and the repair performed; the use of bypass distinguishes this service from a comparable repair performed without it.
Choose the code based on the actual vessel procedure and whether cardiopulmonary bypass was used. Documentation should support the vessel involved, the repair technique, and bypass use. This major surgery has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this service.

33320 billing questions
How does this code differ from 33321?
This code is for major-vessel repair with cardiopulmonary bypass. Code 33321 describes the corresponding repair without bypass.
Should this code be used when a graft is inserted?
Compare the operative service with the major-vessel graft codes, including 33330 and 33335. Those codes describe graft insertion; this code describes vessel repair with bypass.
Can an assistant surgeon be reported?
CMS indicates that assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation.
Can modifier 50 be used for repair of two vessels?
No. Modifier 50 is inappropriate for this code under the CMS bilateral rule. Report the service supported by the operative documentation.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.
