Official Description

Thoracostomy; with open flap drainage for empyema

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 32036 involves a thoracostomy with open flap drainage specifically for the treatment of empyema, which is an accumulation of pus in the pleural cavity. This surgical intervention is necessary when there is a need to drain an abscess located within the pleural space. The process begins with the physician making a small incision in the chest wall, strategically positioned over the rib that is situated above the empyema collection. To access the pleural space, a segment of the rib is excised, allowing entry into the cavity where the empyema resides. The physician then meticulously breaks down any loculated cavities within the pleural space, which may involve using a fingertip or suction tip to ensure thorough drainage. Following this, the empyema collection is aspirated, and the area is irrigated with an antibiotic solution to help prevent infection. A large bore chest tube is subsequently inserted through a separate incision to facilitate ongoing drainage. In the specific procedure denoted by CPT® Code 32036, an open, U-shaped skin flap is created over the site of the empyema to ensure effective drainage and to maintain the opening for continued fluid removal. This flap is designed to extend sufficiently to reach the pleural cavity without causing tension. Additionally, a section of rib is removed, and the tip of the flap is turned inward and sutured to the parietal pleura, which is the membrane lining the chest wall. This technique allows for open drainage of the empyema collection, promoting healing and recovery.

1. Indications

The procedure described by CPT® Code 32036 is indicated for the management of empyema, which is characterized by the presence of pus in the pleural space. This condition may arise due to various underlying causes, including pneumonia, lung abscess, or post-surgical complications. The primary indications for performing this procedure include:

  • Empyema Collection: The presence of a significant accumulation of pus within the pleural cavity that requires surgical intervention for drainage.
  • Loculated Pleural Effusion: The formation of loculations or pockets of fluid within the pleural space that are not amenable to simple drainage techniques.
  • Failure of Conservative Management: Situations where less invasive treatments, such as thoracentesis or chest tube drainage, have failed to adequately resolve the empyema.

2. Procedure

The procedure for CPT® Code 32036 involves several critical steps to ensure effective drainage of the empyema. The steps are as follows:

  • Step 1: Incision and Rib Excision A small incision is made in the chest wall directly over the rib that is positioned above the empyema collection. The surgeon then excises a short segment of the rib to gain access to the pleural space.
  • Step 2: Accessing the Pleural Space Once the rib segment is removed, the surgeon enters the pleural cavity. This access allows for the identification and management of the empyema collection.
  • Step 3: Dissection of Loculations The surgeon carefully dissects the pleural space cavities, also known as loculations, using either a fingertip or suction tip to break them down and facilitate drainage.
  • Step 4: Aspiration and Irrigation The empyema collection is aspirated to remove the pus, and the pleural space is irrigated with an antibiotic solution to reduce the risk of infection.
  • Step 5: Chest Tube Placement A large bore chest tube is inserted into the empyema pocket through a separate incision site to allow for continuous drainage of the fluid.
  • Step 6: Creation of U-Shaped Flap An open, U-shaped skin flap is created over the empyema site to facilitate drainage. The flap is designed to reach the pleural cavity without tension.
  • Step 7: Suturing the Flap The tip of the skin flap is turned inward and sutured to the parietal pleura, which is the lining of the chest wall, ensuring that the empyema collection can drain openly.

3. Post-Procedure

After the completion of the procedure, patients typically require monitoring for any complications, such as infection or bleeding. The chest tube placed during the procedure will remain in situ to facilitate ongoing drainage of any residual fluid. Patients may also receive antibiotics to prevent infection. The expected recovery period can vary based on the individual patient's condition and the extent of the empyema. Follow-up care is essential to assess the effectiveness of the drainage and to determine if further interventions are necessary. Regular imaging studies may be performed to monitor the pleural space and ensure that the empyema is resolving appropriately.

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.
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.)
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).
