What 33020 covers
A cardiac or thoracic surgeon opens the pericardium to remove a clot or foreign body, such as retained material causing compression around the heart. This is an operative service, commonly performed in a hospital operating room when the problem requires direct surgical access rather than needle or catheter drainage. The procedure may be performed with or without cardiopulmonary bypass.
Report the code when the operative record supports pericardial incision for clot or foreign-body removal; a pericardial window for effusion or pericardial tissue resection is a different service. The major-surgery global period includes 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. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

33020 billing questions
How does this differ from pericardiocentesis?
This code is for surgical pericardial access to remove a clot or foreign body. Pericardiocentesis uses needle or catheter access to drain pericardial fluid.
Is a pericardial window reported with this code?
A window created to provide drainage is a distinct service, generally represented by 33025. Choose based on the operation documented, not simply the fact that the pericardium was opened.
What documentation supports reporting 33020?
The operative report should establish the pericardial incision and removal of a clot or foreign body. It should also describe the operative approach and whether cardiopulmonary bypass was used.
Can modifier 50 be used?
No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.
How are other procedures in the same session paid?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures performed in the same session are subject to reduction. The code has a 90-day global period for related postoperative care.
May an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
