Official Description

Thoracotomy, with diagnostic biopsy(ies) of lung nodule(s) or mass(es) (eg, wedge, incisional), unilateral

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 32097 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 nodules or masses, which are abnormal growths within the lung tissue. A lung nodule is defined as a small, rounded growth that can be detected on imaging studies such as chest X-rays or CT scans. The thoracotomy is typically unilateral, meaning it is performed on one side of the chest. During the procedure, the surgeon makes a small anterior incision between the ribs, usually in the second, third, fourth, or fifth intercostal space, depending on the location of the nodule or mass to be biopsied. The surgical approach involves dividing the pectoralis and intercostal muscles to expose the pleura, the membrane surrounding the lungs. The ribs are then spread apart to allow access to the lung tissue. The pleura is incised, and the lung may be collapsed if necessary to facilitate the biopsy. The surgeon examines the exposed lung area, and tissue samples are obtained either by incising the lung or excising a triangular wedge of lung tissue. After the biopsy, the area is closed with mattress sutures, and a chest tube may be placed to drain any fluid or air from the pleural space. Finally, the lung is reinflated, and the chest incision is closed in layers, ensuring proper healing and recovery.

1. Indications

The procedure described by CPT® Code 32097 is indicated for the evaluation of lung nodules or masses that may be present in the lung tissue. The following conditions may warrant this procedure:

  • Suspicion of Lung Cancer Biopsy may be necessary to determine the presence of malignancy in lung nodules.
  • Unexplained Lung Masses When imaging studies reveal lung masses that require further investigation to ascertain their nature.
  • Persistent Lung Nodules Nodules that have not resolved over time and require histological examination to rule out serious conditions.

2. Procedure

The procedure for CPT® Code 32097 involves several critical steps to ensure accurate biopsy of the lung nodule or mass. The following outlines the procedural steps:

  • Step 1: Anesthesia and Positioning The patient is placed under general anesthesia, and appropriate positioning is ensured to provide optimal access to the thoracic cavity.
  • 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 nodule or mass.
  • Step 3: Muscle Division The pectoralis and intercostal muscles are carefully divided to expose the pleura, the membrane surrounding the lungs.
  • Step 4: Rib Spreading The ribs are spread apart to allow access to the lung tissue, facilitating the next steps of the procedure.
  • Step 5: Pleura Incision The pleura is incised, and if necessary, the lung is collapsed to provide a clearer view of the area to be biopsied.
  • Step 6: Examination of Lung The exposed area of the lung is examined for the presence of nodules or masses that require biopsy.
  • Step 7: Tissue Sampling Clamps are applied to the area to be biopsied, and the lung is incised to obtain one or more tissue samples from the nodule or mass. Alternatively, a triangular wedge of lung tissue may be excised for analysis.
  • Step 8: Closure of Biopsy Site The biopsy area is closed using mattress sutures to ensure proper healing.
  • Step 9: Chest Tube Placement A chest tube or catheter may be placed within the pleural space as needed to drain any fluid or air that may accumulate post-procedure.
  • Step 10: Final Closure The lung is fully inflated, and the chest incision is closed in layers around the chest tube, ensuring a secure and stable closure.

3. Post-Procedure

After the completion of the thoracotomy and biopsy, the patient is monitored for any complications that may arise. Post-procedure care may include pain management, monitoring for signs of infection, and ensuring proper lung function. The chest tube, if placed, will be monitored for drainage and may be removed once it is no longer needed. Patients are typically advised on activity restrictions and follow-up appointments to discuss biopsy results and further management based on the findings.

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).
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.
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).
