Thoracoscopy, surgical; with partial pulmonary decortication

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Thoracoscopy, surgical; with partial pulmonary decortication (CPT® Code 32651) is a minimally invasive surgical procedure that involves the removal of a thickened fibrin layer, known as the rind or peel, from the outer surface of part of the lung. This procedure is typically performed using video-assisted thoracoscopic surgery (VATS), which allows for enhanced visualization and precision during the operation. The approach begins with a small incision made between the ribs, usually at the fifth or sixth intercostal space, just below the tip of the scapula. This incision provides access to the pleural space, where the pleura is identified and a thoracoscope is introduced. The thoracoscope is a specialized instrument that enables the surgeon to visualize the internal structures of the thoracic cavity. During the procedure, any fluid present in the pleural space is aspirated, and the area is thoroughly explored. Additional incisions are made to allow for the introduction of surgical instruments necessary for the decortication process. The surgeon carefully dissects the thickened fibrin layer from the underlying visceral pleura, ensuring that all affected portions of the lung are addressed. This procedure is indicated for patients with conditions that lead to the formation of fibrous tissue around the lung, which can restrict lung expansion and impair respiratory function.

1. Indications

Partial pulmonary decortication (CPT® Code 32651) is indicated for patients who present with conditions that result in the formation of a thickened fibrin layer on the pleural surface of the lung. These conditions may include:

  • Empyema - A collection of pus in the pleural cavity, often resulting from infection.
  • Fibrothorax - The presence of fibrous tissue in the pleural space, which can restrict lung expansion.
  • Pleural effusion - Accumulation of fluid in the pleural space that may lead to thickening of the pleura.

2. Procedure

The procedure for partial pulmonary decortication (CPT® Code 32651) involves several key steps:

  • Step 1: Incision and Access - A small posterolateral incision is made between the ribs, typically at the fifth or sixth intercostal space, just below the tip of the scapula. This incision allows access to the pleural space.
  • Step 2: Introduction of Thoracoscope - The pleura is identified through digital palpation, and a trocar is inserted to introduce the thoracoscope into the pleural cavity. This instrument provides visualization of the internal thoracic structures.
  • Step 3: Exploration and Fluid Aspiration - Once inside the pleural space, any fluid present is aspirated, and the area is explored to assess the extent of the thickened fibrin layer.
  • Step 4: Additional Incisions - Two or more additional portal incisions are made to facilitate the introduction of surgical instruments necessary for the decortication process.
  • Step 5: Decortication - The surgeon identifies the thickened fibrin layer and determines the correct decortication plane. The fibrin layer is then grasped and dissected from the underlying visceral pleura, ensuring that all affected portions of the lung are addressed.
  • Step 6: Closure - After the decortication is completed, one or more chest tubes are placed to facilitate drainage, and the incisions are closed.

3. Post-Procedure

Following the partial pulmonary decortication procedure, patients are typically monitored for any complications, such as bleeding or infection. The placement of chest tubes allows for the drainage of any residual fluid or air from the pleural space, which is crucial for proper lung expansion during the recovery phase. Patients may experience some discomfort at the incision sites, and pain management strategies will be implemented as needed. 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.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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).
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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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.)
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).
