Official Description

Thoracotomy; with diagnostic wedge resection followed by anatomic lung resection (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Thoracotomy with diagnostic wedge resection is a surgical procedure that involves making an incision in the chest to access the lungs. This procedure is specifically designed to evaluate diseased or damaged lung tissue. The diagnostic wedge resection allows the surgeon to remove a small, wedge-shaped portion of the lung, which is then sent for pathological examination. The results of this examination are critical as they inform the surgeon about the extent of the disease and help determine the appropriate course of action regarding further lung resection. The procedure is performed through a skin incision made at the front of the chest, which may be extended around the back to provide adequate access to the affected lung area. During the operation, soft tissues are carefully dissected to expose the ribs, and the chest cavity is entered through the intercostal space. In some cases, a rib may be removed to enhance access to the lung. The ultimate goal of this procedure is to obtain a clear diagnosis that will guide subsequent treatment decisions, including whether a more extensive anatomic lung resection is necessary during the same surgical session.

1. Indications

The procedure is indicated for the evaluation of lung conditions that may involve diseased or damaged lung tissue. The following are specific indications for performing a thoracotomy with diagnostic wedge resection:

  • Suspected Lung Tumors The procedure is often performed when there is a suspicion of lung tumors, whether benign or malignant, to obtain tissue for histological analysis.
  • Interstitial Lung Disease It may be indicated in cases of interstitial lung disease where a definitive diagnosis is required to guide treatment options.
  • Pulmonary Infections The procedure can be utilized to assess and obtain samples from areas of the lung affected by severe infections that do not respond to standard treatments.
  • Unexplained Lung Symptoms It is indicated for patients presenting with unexplained lung symptoms, such as persistent cough or unexplained respiratory distress, where further investigation is warranted.

2. Procedure

The procedure involves several critical steps to ensure proper access and evaluation of the lung tissue. The following outlines the procedural steps:

  • Step 1: Anesthesia and Positioning The patient is placed under general anesthesia, and appropriate positioning is ensured to facilitate access to the chest cavity. Typically, the patient is positioned supine or in a lateral decubitus position, depending on the lung being accessed.
  • Step 2: Incision A skin incision is made in the front of the chest at the level of the diseased or damaged lung tissue. The incision may be extended around the back to a point under the shoulder blade as necessary to provide adequate exposure.
  • Step 3: Dissection and Rib Exposure Soft tissues are carefully dissected to expose the ribs. This step is crucial for gaining access to the thoracic cavity. The surgeon may need to remove a rib to enhance visibility and access to the lung.
  • Step 4: Entry into the Chest Cavity The chest cavity is entered through the intercostal space, allowing the surgeon to visualize the lung and surrounding structures. This entry point is selected based on the location of the abnormal lung tissue.
  • Step 5: Identification and Resection of Abnormal Tissue The section of lung containing the abnormal tissue is identified. A wedge of tissue is excised for diagnostic examination, ensuring that the sample is representative of the diseased area.
  • Step 6: Pathology Examination A separately reportable pathology exam is performed on the excised tissue. The results of this examination are critical for determining the next steps in the patient's treatment plan, including whether an anatomic lung resection is necessary.

3. Post-Procedure

After the procedure, the patient is monitored in a recovery area until the effects of anesthesia wear off. Post-operative care includes managing pain, monitoring for any complications such as bleeding or infection, and ensuring proper lung function. Patients may require chest tube placement to facilitate drainage of any fluid or air that may accumulate in the chest cavity. The recovery period can vary based on the extent of the surgery and the patient's overall health. Follow-up appointments are essential to review pathology results and to discuss further treatment options based on the findings from the diagnostic wedge resection.

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.
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).
