About 33305: Heart wound repair with bypass
Report this code when a surgeon repairs a wound of the heart using cardiopulmonary bypass, such as during emergency surgery for cardiac injury.
A cardiac surgeon uses this code to repair a wound in the heart while the patient is supported by cardiopulmonary bypass. A typical setting is a hospital operating room during urgent surgery for a penetrating chest injury or an injury to the heart wall. The service is the repair itself, not exploration alone; the operative record should identify the heart injury and document that bypass was used during repair.
Choose this code rather than 33300 when cardiopulmonary bypass supports the repair. Document the injury, repair performed, and bypass use in the operative report. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate for this code. CMS may pay an assistant at surgery; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

33305 billing questions
How does 33305 differ from 33300?
Use 33305 when cardiopulmonary bypass is used for the heart wound repair. Use 33300 for repair without bypass.
Can 33305 be reported for exploration without a repair?
No. This code represents repair of a heart wound with bypass. When the surgeon explores the heart but does not repair a wound, consider the applicable exploration code instead.
Should modifier 50 be appended for wounds on both sides of the heart?
No. Modifier 50 is inappropriate for this code; CMS does not apply a bilateral adjustment.
What postoperative care is included in the global period?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
CMS may pay an assistant at surgery. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
