CPT® Code 33020

The procedure described by CPT® Code 33020 involves a pericardiotomy, which is a surgical intervention aimed at accessing the pericardium, the protective fibrous membrane surrounding the heart. This procedure is specifically performed to remove either a blood clot or a foreign body that may be present within the pericardial space. The approach to the heart can vary based on the specific circumstances and the location of the pericardiotomy; common methods include a subxiphoid approach, median sternotomy, or anterior thoracotomy. Each of these techniques allows the surgeon to effectively expose the heart and the pericardium. In cases where blunt trauma has led to the accumulation of blood within the pericardial cavity, the surgeon will carefully grasp and retract the pericardium away from the heart to gain access. A small incision, or nick, is made in the pericardium to facilitate the evacuation of blood and fluid. Following this, the pericardial space is thoroughly examined to locate the blood clot, which is then removed. If a foreign body is identified, it is grasped with forceps and extracted. To ensure proper drainage of the pericardial space post-procedure, a chest tube is typically placed into the pericardial cavity, with additional tubes inserted as necessary to manage any further fluid accumulation.
