Official Description

Creation of pericardial window or partial resection for drainage

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 33025 involves the creation of a pericardial window or the partial resection of the pericardium, primarily aimed at facilitating drainage. This surgical intervention is performed using an open approach, which can include techniques such as the subxiphoid approach, median sternotomy, or anterior thoracotomy. The subxiphoid approach is often preferred due to its less invasive nature and the ease of access it provides to the pericardial space. During the procedure, the linea alba, which is the fibrous structure that runs down the midline of the abdomen, is divided just below the xiphoid process, and this process may involve excising the xiphoid process itself if necessary. Once the peritoneum is retracted, the pericardium, the fibrous sac surrounding the heart, is exposed and incised to allow for the aspiration of any fluid present, which is subsequently sent to the laboratory for culture analysis. The creation of a pericardial window or the partial resection of the pericardial sac is achieved by resecting a section of approximately 3-4 cm of the pericardial sac. Following this, the pericardium is carefully examined, and a sponge may be introduced to break up any loculated fluid collections. If required, a second window can be created using the same technique. To ensure effective drainage of the pericardial space, a chest tube is placed into the pericardial window, allowing for continuous removal of fluid and preventing potential complications associated with fluid accumulation around the heart.

1. Indications

The procedure described by CPT® Code 33025 is indicated for various conditions that necessitate the drainage of fluid from the pericardial space. These indications may include:

  • Pericardial Effusion - The accumulation of excess fluid in the pericardial cavity, which can lead to cardiac compression and impaired heart function.
  • Cardiac Tamponade - A serious condition where fluid accumulation exerts pressure on the heart, hindering its ability to pump effectively.
  • Infectious Processes - Conditions such as pericarditis, where inflammation of the pericardium occurs, often accompanied by fluid accumulation that requires drainage.
  • Malignancy - Tumors that may cause fluid buildup in the pericardial space, necessitating intervention for symptom relief and diagnostic purposes.

2. Procedure

The procedure for creating a pericardial window or performing a partial resection of the pericardium involves several critical steps, which are detailed as follows:

  • Step 1: Approach The surgeon selects an appropriate surgical approach, typically the subxiphoid approach, which is less invasive. The linea alba is carefully divided just below the xiphoid process, and if necessary, the xiphoid process itself may be excised to facilitate access to the pericardial space.
  • Step 2: Exposure Once the linea alba is divided, the peritoneum is retracted to expose the pericardium. The pericardium is then incised to allow for the aspiration of any fluid present in the pericardial cavity.
  • Step 3: Aspiration The fluid that has accumulated in the pericardial space is aspirated using a syringe or suction device. This fluid is collected and sent to the laboratory for culture to identify any infectious agents or other abnormalities.
  • Step 4: Resection A pericardial window or partial resection of the pericardial sac is performed by resecting a section of approximately 3-4 cm of the pericardial sac. This step is crucial for allowing adequate drainage and preventing future fluid accumulation.
  • Step 5: Examination After resection, the pericardium is examined for any loculated fluid collections. A sponge may be introduced into the pericardial space to break up these loculations, ensuring that all fluid can be effectively drained.
  • Step 6: Additional Window If necessary, a second pericardial window may be created using the same technique to enhance drainage capabilities.
  • Step 7: Drain Placement Finally, a chest tube is placed into the pericardial window to facilitate continuous drainage of the pericardial space, thereby preventing the reaccumulation of fluid and reducing the risk of complications.

3. Post-Procedure

Post-procedure care following the creation of a pericardial window or partial resection of the pericardium involves monitoring the patient for any signs of complications, such as bleeding or infection. The chest tube placed during the procedure will typically remain in place for a period to ensure adequate drainage of the pericardial space. Healthcare providers will assess the output from the chest tube and may perform imaging studies to evaluate the effectiveness of the drainage. Patients may require pain management and supportive care during their recovery. The duration of hospital stay and recovery will depend on the individual patient's condition and response to the procedure.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
GC This service has been performed in part by a resident under the direction of a teaching physician
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
