Official Description

Removal of lung, pneumonectomy;

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 32440 refers to the surgical procedure known as pneumonectomy, which involves the complete removal of a lung. This procedure is typically indicated for patients with severe lung conditions, such as lung cancer, that necessitate the removal of an entire lung to prevent the spread of disease or to alleviate significant respiratory issues. The operation is performed through a posterolateral thoracic incision, which is strategically made in the intercostal space, starting just below the shoulder blade and extending around to the front of the chest. In some cases, to enhance access to the lung, a rib may be removed during the procedure. Once access is achieved, the lung is deflated, and the major blood vessels supplying the lung are carefully ligated and divided to prevent excessive bleeding. The main bronchus, which is the airway leading to the lung, is then clamped and incised, allowing for the complete removal of the lung. After the lung is excised, the remaining segment of the bronchus is either stapled or sutured closed to ensure proper healing. Following the removal, a chest tube is placed to facilitate drainage and prevent fluid accumulation, and the chest incision is subsequently closed. This procedure is critical in managing advanced pulmonary diseases and requires careful consideration of the patient's overall health and specific medical conditions.

1. Indications

The procedure described by CPT® Code 32440, pneumonectomy, is indicated for various severe lung conditions. The following are explicitly provided indications for performing this procedure:

  • Lung Cancer - The primary indication for a pneumonectomy is the presence of lung cancer that is localized to one lung and cannot be treated effectively with less invasive methods.
  • Severe Lung Disease - Conditions such as chronic obstructive pulmonary disease (COPD) or pulmonary fibrosis that significantly impair lung function may necessitate the removal of an entire lung.
  • Trauma - Severe lung trauma that results in irreparable damage to the lung may require pneumonectomy as a life-saving measure.
  • Infection - In cases of extensive lung infections, such as tuberculosis or lung abscesses, where the affected lung cannot be salvaged, pneumonectomy may be indicated.

2. Procedure

The pneumonectomy procedure involves several critical steps, each essential for the successful removal of the lung. The following procedural steps are outlined:

  • Step 1: Incision - A posterolateral thoracic incision is made in the intercostal space, beginning just below the shoulder blade and extending around to the front of the chest. This incision provides the surgeon with adequate access to the thoracic cavity.
  • Step 2: Rib Removal (if necessary) - If additional access is required, a rib may be removed to facilitate the surgical procedure. This step is performed with caution to minimize damage to surrounding structures.
  • Step 3: Lung Deflation and Vascular Control - The lung is deflated to reduce its size and facilitate removal. Major blood vessels supplying the lung are then carefully ligated and divided to prevent excessive bleeding during the procedure.
  • Step 4: Bronchus Clamping and Incision - The main bronchus, which is the airway leading to the lung, is clamped and incised. This step is crucial for isolating the lung from the rest of the respiratory system.
  • Step 5: Lung Removal - The lung is then completely removed from the thoracic cavity. This step requires careful handling to avoid damaging surrounding tissues.
  • Step 6: Closure of the Bronchus - After the lung is excised, the remaining segment of the bronchus is either stapled or sutured closed to ensure proper healing and prevent air leaks.
  • Step 7: Chest Tube Placement - A chest tube is placed to facilitate drainage of any fluid or air that may accumulate in the thoracic cavity post-surgery.
  • Step 8: Incision Closure - Finally, the chest incision is closed, completing the surgical procedure.

3. Post-Procedure

After the pneumonectomy, patients typically require close monitoring in a recovery area. Post-procedure care includes managing pain, monitoring respiratory function, and ensuring that the chest tube is functioning properly to prevent fluid accumulation. Patients may experience a range of symptoms, including shortness of breath and fatigue, as they adjust to having one lung. Rehabilitation and pulmonary therapy may be recommended to aid recovery and improve lung function. Follow-up appointments are essential to monitor the surgical site and overall health, ensuring that any complications are addressed promptly.

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).
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.)
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).
