Decortication and parietal pleurectomy

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 32320 involves decortication and parietal pleurectomy, which are surgical interventions aimed at addressing issues related to the pleura, the serous membrane surrounding the lungs. The pleura consists of two layers: the parietal pleura, which lines the chest wall, and the visceral pleura, which covers the lungs themselves. In certain medical conditions, the visceral pleura can become encased in a thick layer of fibrin, leading to restricted lung expansion and impaired respiratory function. This thickened layer must be surgically removed to restore normal lung mechanics. The procedure begins with a posterolateral incision in the chest, typically at the fifth or sixth intercostal space, allowing access to the lung. During the decortication process, the surgeon not only removes the parietal pleura but also meticulously strips away the thickened fibrin layer from the visceral pleura. This dual approach is essential for ensuring that all areas of the lung that are encased by the fibrin layer are adequately addressed, thereby facilitating improved lung expansion and function post-surgery. Following the procedure, chest tubes are often placed to assist with drainage, and the incision is subsequently closed to promote healing.

1. Indications

The procedure of decortication and parietal pleurectomy (CPT® Code 32320) is indicated for patients experiencing conditions that lead to the thickening of the pleura, particularly when the visceral pleura becomes encased in a fibrin layer that restricts lung expansion. This may occur in various clinical scenarios, including:

  • Empyema: A collection of pus in the pleural cavity, often resulting from infection, which can lead to the formation of a thick fibrinous layer.
  • Fibrothorax: A condition characterized by the presence of fibrous tissue in the pleural space, which can restrict lung movement.
  • Pleural effusion: Accumulation of fluid in the pleural space that may become complicated by fibrinous adhesions.
  • Post-surgical complications: Following thoracic surgery, patients may develop thickened pleura that necessitates intervention to restore lung function.

2. Procedure

The procedure for decortication and parietal pleurectomy involves several critical steps to ensure effective removal of the thickened pleura and restoration of lung function. The steps are as follows:

  • Step 1: The surgeon begins by making a posterolateral incision in the chest, typically at the fifth or sixth intercostal space. This incision provides access to the pleural cavity and the underlying lung.
  • Step 2: Once the chest cavity is accessed, the lung is carefully exposed to allow for a clear view of the pleura. The surgeon assesses the condition of both the parietal and visceral pleura.
  • Step 3: In the case of parietal pleurectomy, an incision is made in the parietal pleura, which is then stripped off the chest wall using both blunt and sharp dissection techniques. This step is crucial for removing the outer layer of the pleura.
  • Step 4: For the decortication aspect of the procedure, the surgeon identifies the thickened fibrin layer covering the visceral pleura. An incision is made into this layer to facilitate dissection.
  • Step 5: The fibrin layer is grasped and meticulously dissected from the underlying visceral pleura. The surgeon ensures that all portions of the lung encased by the thickened fibrin layer are addressed to restore normal lung function.
  • Step 6: After the decortication is complete, one or more chest tubes are placed to facilitate drainage of any fluid or air that may accumulate in the pleural space post-operatively.
  • Step 7: Finally, the chest incision is closed, and the patient is monitored for recovery and any potential complications.

3. Post-Procedure

Post-procedure care following decortication and parietal pleurectomy involves monitoring the patient for any signs of complications, such as infection or bleeding. The placement of chest tubes is essential for draining any residual fluid or air from the pleural space, which aids in lung re-expansion. Patients may require pain management and respiratory therapy to support recovery. The expected recovery period can vary based on the individual patient's condition and the extent of the surgery performed. Follow-up evaluations are necessary to assess lung function and ensure that the pleural space is healing appropriately.

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.
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).
