Official Description

Thoracoscopy; with biopsy(ies) of pleura

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Thoracoscopy with biopsy of the pleura is a minimally invasive surgical procedure used to examine the pleural space, which is the area between the lungs and the chest wall. This procedure allows for direct visualization of the pleura, the membrane surrounding the lungs, and is typically performed to investigate abnormalities such as pleural effusions, tumors, or infections. During thoracoscopy, various techniques may be employed to access the pleural space safely. One common method involves blunt entry, where a clamp is passed over a rib to penetrate the pleura. This is followed by a digital inspection of the entry site to confirm sufficient space for the insertion of the thoracoscope, a specialized instrument used for viewing the pleura. The thoracoscope is then inserted under direct vision, allowing the physician to inspect the pleura for any irregularities. In some cases, fluid may be removed from the pleural space using suction catheters to facilitate a clearer view. Tissue samples, or biopsies, are collected from the pleura to aid in diagnosis. Another technique may involve making a small incision in the chest wall to insert a trocar, which creates an entry point for the thoracoscope. This method may also include the induction of an artificial pneumothorax by injecting air into the pleural space, enhancing visualization. Throughout the procedure, any lesions or abnormalities are documented, and photographs may be taken prior to obtaining biopsies. After the examination, a chest tube or catheter may be placed if necessary, and the incisions are closed to complete the procedure.

1. Indications

The thoracoscopy with biopsy of the pleura is indicated for various clinical scenarios where direct visualization and sampling of the pleura are necessary. The following conditions may warrant this procedure:

  • Pleural Effusion - Accumulation of fluid in the pleural space that requires evaluation to determine the underlying cause.
  • Pleural Tumors - Suspected malignancies or neoplastic lesions in the pleura that need to be assessed and biopsied for histological examination.
  • Pleural Infection - Infections such as empyema that may necessitate drainage and biopsy to identify the causative organism.
  • Unexplained Chest Pain - Situations where the cause of chest pain is unclear and may be related to pleural pathology.

2. Procedure

The procedure for thoracoscopy with biopsy of the pleura involves several key steps to ensure effective examination and sampling of the pleura. The following outlines the procedural steps:

  • Step 1: Preparation - The patient is positioned appropriately, typically in a semi-upright position, to facilitate access to the pleural space. Anesthesia is administered to ensure patient comfort during the procedure.
  • Step 2: Accessing the Pleural Space - A clamp is passed over a rib to create a blunt entry into the pleura. The entry site is inspected digitally to confirm adequate space for the thoracoscope's insertion.
  • Step 3: Insertion of the Thoracoscope - The thoracoscope is inserted under direct vision into the pleural space. This allows for a thorough inspection of the pleura, where any abnormalities can be noted.
  • Step 4: Fluid Management - If fluid is present in the pleural space, it may be evacuated using suction catheters to improve visibility and facilitate further examination.
  • Step 5: Biopsy Collection - One or more tissue samples are taken from the pleura for diagnostic purposes. This may involve using specialized instruments to obtain adequate samples.
  • Step 6: Additional Techniques - In some cases, a small intercostal incision may be made to insert a trocar into the intercostal space. Air may be injected to induce an artificial pneumothorax, enhancing visualization of the pleura.
  • Step 7: Documentation - Any lesions or abnormalities observed during the procedure may be photographed for medical records prior to biopsy collection.
  • Step 8: Closure - After the examination and biopsy are complete, the thoracoscope is withdrawn, air is evacuated from the pleural space, and any portal incisions are closed. A chest tube or catheter may be placed as needed to facilitate drainage.

3. Post-Procedure

Post-procedure care following thoracoscopy with biopsy of the pleura involves monitoring the patient for any complications and ensuring proper recovery. Patients may be observed for signs of respiratory distress, bleeding, or infection. If a chest tube has been placed, it will be monitored for proper drainage of any residual fluid or air. Pain management is also an important aspect of post-procedure care, and patients may be prescribed analgesics as needed. Follow-up imaging or assessments may be scheduled to evaluate the pleural space and ensure that any issues have been adequately addressed. The healthcare team will provide specific instructions regarding activity restrictions and signs of complications that should prompt immediate medical attention.

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).
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.
