Official Description

Thoracoscopy, surgical; with removal of a single lung segment (segmentectomy)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Surgical thoracoscopy, commonly known as video-assisted thoracoscopic surgery (VATS), is a minimally invasive surgical procedure used to access the thoracic cavity. This technique allows surgeons to perform various interventions within the chest, particularly focusing on the lungs. A lung segmentectomy specifically refers to the surgical removal of a small portion of the lung, known as a lung segment. This procedure is typically indicated for patients with early-stage lung cancer that is localized to a small area of the lung, making it possible to preserve surrounding healthy lung tissue rather than removing an entire lobe. The approach involves making small incisions in the chest wall to insert a camera and surgical instruments, which enhances visualization and precision during the operation. The use of thoracoscopy minimizes trauma to the chest wall, reduces postoperative pain, and promotes quicker recovery compared to traditional open surgery. The procedure is performed under general anesthesia and requires careful planning and execution to ensure the complete removal of the affected lung segment while maintaining the integrity of the remaining lung structure.

1. Indications

The procedure of lung segmentectomy via thoracoscopy is indicated for specific clinical scenarios, particularly when localized lung pathology is present. The following conditions may warrant this surgical intervention:

  • Early Stage Lung Cancer - The primary indication for a segmentectomy is the presence of early-stage lung cancer that is confined to a small portion of the lung, allowing for targeted removal without the need for lobectomy.
  • Localized Lung Lesions - Patients with benign or malignant lesions that are small and well-defined may also be candidates for this procedure, as it allows for the removal of the lesion while preserving lung function.
  • Metastatic Disease - In some cases, lung segmentectomy may be performed to remove metastatic tumors that have spread to the lung from other primary sites, provided that the lesions are isolated and resectable.

2. Procedure

The surgical procedure for lung segmentectomy via thoracoscopy involves several critical steps to ensure successful resection of the lung segment. The following outlines the procedural steps:

  • Step 1: Incision and Access - A 1 cm portal incision is made at the 7th or 8th intercostal space along the posterior axillary line to facilitate the insertion of a camera. A second, larger 4 cm access incision is created at the 5th or 6th intercostal space anteriorly, allowing for the introduction of surgical instruments.
  • Step 2: Induction of Pneumothorax - Once access to the pleural space is achieved, air is injected to induce an artificial pneumothorax. This maneuver enhances visualization of the lung and surrounding structures during the procedure.
  • Step 3: Exploration - The pleura and lung are carefully explored to assess for any evidence of metastatic disease and to determine the resectability of the lesion. This exploration is crucial for planning the surgical approach.
  • Step 4: Division of Pleura - The pleura is divided at the pleural-parenchymal reflection, allowing for better access to the lung segment of interest. Hilar structures are also explored to identify relevant vascular and bronchial anatomy.
  • Step 5: Identification and Ligation of Vessels - The segmental pulmonary vein associated with the lung segment is identified and staple ligated to prevent bleeding during the resection. This step is essential for ensuring hemostasis.
  • Step 6: Additional Dissection - Further pleural dissection is performed as necessary to expose the segmental arteries, which are then identified and divided to facilitate the removal of the lung segment.
  • Step 7: Bronchial Resection - The segmental bronchus is encircled, stapled, and divided, allowing for the complete removal of the targeted lung segment.
  • Step 8: Resection of Lung Parenchyma - The lung may be temporarily reinflated to enhance the identification of the segment to be removed. The lung parenchyma is then resected using a stapling device, ensuring a clean and precise cut.
  • Step 9: Removal of Resection - After the lung segment has been resected, an endobag is introduced to facilitate the safe removal of the segment from the thoracic cavity.
  • Step 10: Closure and Recovery - Following the removal of the lung segment, bleeding is controlled, instruments are withdrawn, the lung is reinflated, and a chest tube is placed to assist with drainage and facilitate recovery.

3. Post-Procedure

Post-procedure care following a lung segmentectomy via thoracoscopy involves monitoring for complications and ensuring proper recovery. Patients are typically observed for signs of bleeding, infection, or respiratory distress. The chest tube placed during the procedure is monitored and may be removed once adequate lung expansion is confirmed and fluid drainage is minimal. Pain management is an important aspect of post-operative care, and patients may be prescribed analgesics to manage discomfort. Rehabilitation and pulmonary function exercises may be recommended to aid in recovery and restore lung function. Follow-up appointments are essential to assess healing and to monitor for any recurrence of disease.

GC This service has been performed in part by a resident under the direction of a teaching physician
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).
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.
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).
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.
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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 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).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
