Official Description

Thoracotomy; with exploration

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A thoracotomy is a surgical procedure that involves making a large incision in the chest to gain access to the thoracic cavity for exploration purposes. This procedure is typically performed when there is a need to investigate potential abnormalities within the chest, such as issues affecting the heart, lungs, or mediastinal structures. The incision may involve splitting the sternum, which is the breastbone, or removing a portion of one or more ribs to facilitate access. When the sternum is split, a chest spreader is utilized to hold the chest cavity open, allowing the surgeon to thoroughly examine the internal structures. Alternatively, if the incision is made in the anterolateral or posterolateral region of the chest wall, the surgeon will divide the pectoralis and intercostal muscles to expose the pleura, which is the membrane surrounding the lungs. During the procedure, the ribs may be spread apart or a section of one or more ribs may be excised to provide adequate visibility and access. Once the pleura is opened, the surgeon can inspect the heart, lungs, and surrounding mediastinal structures for any abnormalities. After the exploration is complete, a chest tube or catheter may be placed in the pleural space if necessary to facilitate drainage. Finally, the chest spreaders are removed, and the incision is meticulously closed in layers around the chest tube to ensure proper healing and minimize complications.

1. Indications

The thoracotomy procedure is indicated for various clinical situations where direct access to the thoracic cavity is necessary for diagnosis or treatment. Common indications include:

  • Trauma - Evaluation and management of traumatic injuries to the chest, including penetrating or blunt trauma that may affect the lungs, heart, or major blood vessels.
  • Suspicion of Tumors - Investigation of suspected tumors or masses within the thoracic cavity that may require biopsy or resection.
  • Pleural Effusion - Assessment and management of significant pleural effusions that may require drainage or further evaluation.
  • Infection - Exploration for suspected infections, such as empyema or abscesses, that may necessitate surgical intervention.
  • Cardiac Conditions - Access for surgical procedures on the heart, such as valve repair or coronary artery bypass grafting.

2. Procedure

The thoracotomy procedure involves several critical steps to ensure proper access and exploration of the thoracic cavity. The following outlines the procedural steps:

  • Step 1: Anesthesia and Positioning - The patient is placed under general anesthesia to ensure comfort and immobility during the procedure. The patient is typically positioned supine or in a lateral decubitus position, depending on the specific area of the chest being accessed.
  • Step 2: Incision - A large incision is made in the chest wall, which may involve splitting the sternum or making an incision in the anterolateral or posterolateral chest wall. If the sternum is split, a chest spreader is inserted to hold the chest open, providing access to the thoracic cavity.
  • Step 3: Muscle Division - If an incision is made in the chest wall, the pectoralis and intercostal muscles are carefully divided to expose the pleura, the membrane surrounding the lungs.
  • Step 4: Rib Management - The ribs may be spread apart or a portion of one or more ribs may be excised to enhance visibility and access to the thoracic structures.
  • Step 5: Pleura Opening - The pleura is opened to allow direct examination of the heart, lungs, and mediastinal structures. The surgeon inspects these areas for any abnormalities, such as tumors, infections, or other pathological conditions.
  • Step 6: Documentation of Findings - Any abnormalities noted during the exploration are documented for further evaluation and treatment planning.
  • Step 7: Chest Tube Placement - Following the exploration, a chest tube or catheter may be placed within the pleural space as needed to facilitate drainage of any fluid or air that may accumulate.
  • Step 8: Closure - The chest spreaders are removed, and the incision is closed in layers around the chest tube to ensure proper healing and minimize the risk of complications.

3. Post-Procedure

After the thoracotomy procedure, the patient is typically monitored in a recovery area for any immediate complications. Post-procedure care may include pain management, monitoring for signs of infection, and ensuring proper function of the chest tube if placed. The patient may require respiratory therapy to aid in recovery and lung function. Follow-up imaging may be necessary to assess the thoracic cavity and ensure there are no complications such as fluid accumulation or pneumothorax. The expected recovery time can vary based on the extent of the procedure and the patient's overall health, but close monitoring and follow-up care are essential for optimal 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).
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.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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).
