Official Description

Thoracotomy, with diagnostic biopsy(ies) of lung infiltrate(s) (eg, wedge, incisional), unilateral

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 32096 involves a thoracotomy, which is a surgical incision into the chest wall to access the lungs. This specific procedure is performed for the purpose of obtaining diagnostic biopsies of lung infiltrates, which are abnormal substances present in the lung tissue that can lead to opacification visible on a chest x-ray. Such infiltrates may arise from various conditions, including infections, inflammation, fluid accumulation, or hemorrhage. The term 'unilateral' indicates that the procedure is performed on one side of the chest only. During the thoracotomy, the surgeon makes a small anterior incision between the ribs, typically in the second to fifth intercostal spaces, depending on the location of the infiltrate. The surgical approach involves careful dissection of the pectoralis and intercostal muscles to expose the pleura, the membrane surrounding the lungs. Once the pleura is accessed, the surgeon may collapse the lung as necessary to facilitate examination and biopsy of the affected area. The procedure may involve obtaining one or more tissue samples or excising a triangular wedge of lung tissue. After the biopsy is completed, the lung is reinflated, and the incision is meticulously closed, often with the placement of a chest tube to ensure proper drainage and lung expansion postoperatively.

1. Indications

The procedure described by CPT® Code 32096 is indicated for the evaluation of lung infiltrates that may suggest various underlying conditions. The following are the explicit indications for performing this thoracotomy with diagnostic biopsy:

  • Unexplained Lung Infiltrates: The procedure is indicated when imaging studies reveal lung infiltrates that require further investigation to determine the underlying cause.
  • Suspected Infection: It may be performed in cases where there is a suspicion of infectious processes, such as pneumonia or tuberculosis, that are not responding to initial treatments.
  • Inflammatory Conditions: The procedure can be indicated for suspected inflammatory diseases, such as sarcoidosis or interstitial lung disease, where a definitive diagnosis is necessary.
  • Fluid Accumulation: Thoracotomy may be indicated when there is a need to evaluate pleural effusions or other fluid collections in the pleural space.
  • Hemorrhage: The procedure may be warranted in cases of suspected pulmonary hemorrhage where tissue diagnosis is required.

2. Procedure

The procedural steps for CPT® Code 32096 are as follows:

  • Step 1: Anesthesia and Positioning The patient is placed under general anesthesia and positioned appropriately to allow access to the thoracic cavity. The surgical team prepares the area for incision.
  • Step 2: Incision A small anterior incision is made between the ribs, typically in the second, third, fourth, or fifth intercostal space, depending on the location of the lung infiltrate that needs to be biopsied.
  • Step 3: Muscle Dissection The pectoralis major and intercostal muscles are carefully divided to expose the pleura, the membrane surrounding the lungs.
  • Step 4: Rib Spreading The ribs are gently spread apart to provide adequate access to the pleural cavity.
  • Step 5: Pleura Incision The pleura is incised, and the lung may be collapsed as needed to facilitate access to the area of interest. If there is pleural fluid, it may be aspirated at this stage.
  • Step 6: Lung Examination The exposed area of the lung is examined for infiltrates or nodules that require biopsy.
  • Step 7: Biopsy Procedure Clamps are applied to the area designated for biopsy. The lung tissue is incised, and one or more tissue samples are obtained from the infiltrated area. Alternatively, a triangular wedge of lung tissue may be excised for diagnostic purposes.
  • Step 8: Closure of Biopsy Site The biopsy site is closed using mattress sutures to ensure proper healing and minimize complications.
  • Step 9: Chest Tube Placement A chest tube or catheter may be placed within the pleural space as needed to facilitate drainage and lung re-expansion.
  • Step 10: Final Closure The lung is fully inflated, and the chest incision is closed in layers around the chest tube, ensuring a secure closure of the thoracic cavity.

3. Post-Procedure

After the thoracotomy and biopsy procedure, the patient is monitored closely for any 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 lung expansion and recovery. Follow-up imaging may be necessary to assess the lung's condition and the effectiveness of the procedure. The expected recovery time can vary based on the individual patient's health status and the extent of the procedure performed.

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.
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.
