Official Description

Pericardiotomy for removal of clot or foreign body (primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The pericardiotomy procedure, as described by CPT® Code 33020, is indicated in specific clinical scenarios where intervention is necessary to address issues within the pericardial space. The following conditions may warrant this surgical approach:

  • Blood Clot in the Pericardium - This condition may arise due to blunt trauma or other factors leading to the accumulation of blood, necessitating removal to alleviate pressure on the heart.
  • Foreign Body in the Pericardial Space - The presence of a foreign object can cause irritation or complications, requiring surgical intervention for safe extraction.

2. Procedure

The pericardiotomy procedure involves several critical steps to ensure effective access and removal of the clot or foreign body. The following procedural steps are performed:

  • Step 1: Patient Positioning and Anesthesia - The patient is positioned appropriately, typically in a supine position, and general anesthesia is administered to ensure comfort and immobility during the procedure.
  • Step 2: Surgical Approach - The surgeon selects the appropriate surgical approach based on the clinical scenario. This may involve a subxiphoid incision, median sternotomy, or anterior thoracotomy to access the pericardium effectively.
  • Step 3: Exposure of the Pericardium - Once the surgical approach is established, the pericardium is carefully exposed. In cases of blunt trauma, the pericardium is grasped and retracted away from the heart to provide a clear view of the area.
  • Step 4: Incision in the Pericardium - A small nick is made in the pericardium to allow for the evacuation of blood and fluid that may have accumulated in the pericardial space.
  • Step 5: Examination and Removal of Clot or Foreign Body - The pericardial space is thoroughly examined to locate the blood clot or foreign body. The blood clot is removed, or if a foreign body is present, it is grasped with forceps and extracted carefully.
  • Step 6: Drainage Placement - To facilitate proper drainage of the pericardial cavity and prevent fluid accumulation, a chest tube is placed into the pericardial space. Additional chest tubes may be inserted as needed based on the volume of fluid present.

3. Post-Procedure

After the completion of the pericardiotomy, the patient will require monitoring for any complications that may arise. Post-procedure care typically includes observation for signs of bleeding, infection, or cardiac complications. The chest tubes placed during the procedure will be monitored for drainage output, and they may remain in place for a period to ensure adequate drainage of the pericardial space. The healthcare team will provide instructions for follow-up care and any necessary rehabilitation to support the patient's recovery.

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.
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).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient 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).
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).
57 Decision for surgery: an evaluation and management service that resulted in the initial decision to perform the surgery may be identified by adding modifier 57 to the appropriate level of e/m service.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
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.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
