Cardiothoracic surgery
About 33031: Pericardiectomy with cardiopulmonary bypass
Reports surgical removal of part or most of the pericardium with cardiopulmonary bypass, commonly for constrictive disease requiring operative treatment.
A cardiothoracic surgeon removes diseased, thickened, or constricting pericardium while the patient is supported with cardiopulmonary bypass. The operation is typically performed in a hospital operating room for conditions such as constrictive pericarditis when a limited drainage opening would not address the disease. The operative report should establish the extent of pericardial removal and use of bypass.
Choose this code when the documented pericardiectomy is performed with cardiopulmonary bypass; the sibling code 33030 describes the operation without bypass. This major surgery 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 one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate because the pericardium is not paired right-left anatomy. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

33031 billing questions
How does 33031 differ from 33030?
Both describe subtotal or complete pericardial removal. Report 33031 when cardiopulmonary bypass is used; 33030 is the corresponding service without bypass.
Is a pericardial window reported with 33031?
A pericardial window or limited resection for drainage is represented by 33025, not by treating part of the pericardiectomy as a separate window. The operative documentation should clarify the procedure performed.
What documentation supports 33031?
The operative report should describe the pericardial removal and document cardiopulmonary bypass use. It should make clear that the service was a pericardiectomy rather than drainage alone.
Can modifier 50 be used?
No. Modifier 50 is inappropriate because pericardiectomy involves the heart sac, not a paired right and left structure.
How are assistant and co-surgeon services handled?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation, and team surgery is not permitted for this code.
What happens when another procedure is performed in the same session?
The highest-valued procedure is paid in full, with other procedures subject to the standard multiple-procedure reduction to 50%.
