Official Description

Thoracoscopy, surgical; with creation of pericardial window or partial resection of pericardial sac for drainage

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 32659 involves a surgical thoracoscopy, commonly known as video-assisted thoracoscopic surgery (VATS), which is utilized to create a pericardial window or to perform a partial resection of the pericardial sac for the purpose of drainage. The pericardium is a fibrous membrane that encases the heart, and this procedure is typically indicated when there is an accumulation of fluid or other substances in the pericardial space that requires intervention. During the procedure, the physician makes a small incision between the ribs, usually at the sixth or seventh intercostal space along the anterior axillary line, to introduce a videothoracoscope. This minimally invasive approach allows for better visualization and access to the pericardial area. Additional incisions are made to accommodate surgical instruments, facilitating the necessary steps to either create a pericardial window or to partially resect the pericardial sac. The goal of this intervention is to effectively drain the pericardial space, thereby alleviating pressure on the heart and improving patient outcomes.

1. Indications

The procedure described by CPT® Code 32659 is indicated for the following conditions:

  • Pericardial Effusion - Accumulation of fluid in the pericardial space that may cause cardiac compression.
  • Cardiac Tamponade - A serious condition where fluid accumulation exerts pressure on the heart, impairing its ability to pump effectively.
  • Infection or Inflammation - Conditions such as purulent pericarditis that may necessitate drainage to prevent further complications.

2. Procedure

The procedure involves several key steps to ensure effective drainage of the pericardial space:

  • Step 1: Incision and Access - The surgeon begins by making a small incision between the ribs, typically at the sixth or seventh intercostal space along the anterior axillary line. This incision allows for the introduction of a videothoracoscope, which provides visualization of the thoracic cavity.
  • Step 2: Additional Portals - Two additional portal incisions are created at the posterior axillary line, usually at the fifth and eighth intercostal spaces. These portals are used for the insertion of surgical instruments necessary for the procedure.
  • Step 3: Division of the Inferior Pulmonary Ligament - The inferior pulmonary ligament is divided to facilitate access to the pericardial space and to allow for better maneuverability of the instruments.
  • Step 4: Identification and Protection of the Phrenic Nerve - The phrenic nerve, which is crucial for diaphragm function, is identified and carefully protected throughout the procedure to prevent any injury.
  • Step 5: Grasping and Retracting the Pericardium - The pericardium is grasped and retracted away from the heart to provide a clear view and access for the next steps.
  • Step 6: Evacuation of Fluid - Endoscopic scissors are introduced to nick the pericardium, allowing for the evacuation of blood and fluid that has accumulated in the pericardial space.
  • Step 7: Creation of Pericardial Window or Resection - A pericardial window is created, or a partial resection of the pericardial sac is performed by resecting a 3-4 cm section of the pericardial sac to facilitate drainage.
  • Step 8: Examination and Loculation Breakdown - The pericardium is examined, and a sponge may be introduced to break up any loculations that could hinder drainage. A second window may be created if necessary.
  • Step 9: Placement of Chest Tubes - A chest tube is placed into the pericardial window to ensure continuous drainage of the pericardial space. Additionally, a second chest tube is placed in the pleural space to manage any fluid accumulation in that area.

3. Post-Procedure

After the completion of the procedure, the patient is monitored for any complications related to the thoracoscopic approach. The chest tubes placed during the procedure will remain in situ to facilitate ongoing drainage of the pericardial and pleural spaces. Patients may require pain management and will be observed for signs of infection or other post-operative complications. The recovery process will vary based on individual patient factors and the extent of the procedure performed.

This is a primary code that can be used with these additional add-on codes.

32674 Add-on Code MPFS Status: Active Code APC C Thoracoscopy, surgical; with mediastinal and regional lymphadenectomy (List separately in addition to code for primary 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).
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).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
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).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
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).
