Official Description

Thoracotomy; for postoperative complications

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A thoracotomy is a surgical procedure that involves making an incision in the chest wall to access the thoracic cavity. Specifically, CPT® Code 32120 refers to a thoracotomy performed to address postoperative complications that arise following a previous thoracic surgery. During this procedure, the surgeon reopens the existing chest incision, which allows for direct access to the area of concern. In cases where additional exposure is necessary, the surgeon may also open both sides of the chest. This approach enables a thorough exploration of the chest cavity, where the surgeon can assess the previous surgical site and the surrounding tissues for any signs of complications such as bleeding, fluid accumulation, or other issues that may have developed postoperatively. The procedure is critical for managing complications effectively and ensuring patient safety and recovery.

1. Indications

The thoracotomy for postoperative complications, as described by CPT® Code 32120, is indicated in the following scenarios:

  • Postoperative Bleeding The procedure is performed when there is evidence of bleeding that requires surgical intervention to control.
  • Fluid Accumulation It is indicated when there are significant fluid collections in the thoracic cavity that need to be aspirated or drained.
  • Other Surgical Complications The thoracotomy is also indicated for addressing any other complications that may arise from previous thoracic surgeries, necessitating further exploration and treatment.

2. Procedure

The procedure begins with the surgeon reopening the previous chest incision to gain access to the thoracic cavity. If the surgical site requires additional exposure, both sides of the chest may be opened to facilitate a comprehensive examination. A rib or sternal spreader is then inserted to allow for adequate visualization and access to the chest cavity. Once inside, the surgeon carefully explores the area, examining the previous surgical site and surrounding tissues for any signs of complications such as bleeding or fluid accumulation. If bleeding is detected, the surgeon initially controls it using finger pressure, packing, and/or clamps to stabilize the situation. Following this initial control, any vascular injuries are addressed through a combination of ligation and coagulation techniques to prevent further blood loss. Fluid accumulations are aspirated, and specimens may be collected for laboratory analysis if necessary. After addressing all identified complications, chest tubes are placed to facilitate drainage, and the chest incision is subsequently closed to complete the procedure.

3. Post-Procedure

Post-procedure care following a thoracotomy for postoperative complications involves monitoring the patient for any signs of ongoing bleeding or complications. The placement of chest tubes allows for the continuous drainage of any residual fluid or air from the thoracic cavity, which is essential for proper recovery. Patients are typically observed in a postoperative setting where vital signs are closely monitored, and pain management is provided as needed. The recovery process may vary depending on the extent of the complications addressed and the patient's overall health status. Follow-up care is crucial to ensure that any further issues are promptly identified and managed.

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).
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.
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).
