Cardiac surgery
About 33315: Heart exploration with bypass
Report open surgical exploration of the heart performed with cardiopulmonary bypass when the operative service is exploration rather than a definitive repair.
This service is an open operation to examine the heart, with cardiopulmonary bypass used during the procedure. It may include removal of a foreign body when that is part of the exploration. Cardiothoracic surgeons typically perform it in a hospital operating room when direct surgical assessment of the heart is needed and the operative work does not instead represent a separately defined repair or other definitive procedure.
Choose this code based on the operative work and documented use of cardiopulmonary bypass; the report should explain the reason for exploration, findings, any foreign body removal, and procedures performed. It 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 other procedures are subject to the standard multiple procedure reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation. Team surgery is not permitted.

33315 billing questions
How does this differ from 33310?
Both describe heart exploration, but 33315 is the version performed with cardiopulmonary bypass. Use the operative report to establish whether bypass was used.
Can this be reported when a heart wound is repaired?
If the surgeon performs a defined heart-wound repair, compare the operative work with 33300 or 33305 rather than using an exploration code as a substitute. The bypass distinction separates those repair codes.
Is cardiopulmonary bypass separately represented by this code?
Bypass use distinguishes this exploration code from 33310. Document its use in the operative report.
What documentation supports reporting 33315?
Document the indication and findings from the heart exploration, whether a foreign body was removed, and that cardiopulmonary bypass was used.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
What does the 90-day global period include?
It includes the day-before preoperative visit and 90 days of related postoperative care.
