Official Description

Suture and/or ligation of thoracic duct; thoracic approach

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 38381 involves the suture and/or ligation of the thoracic duct through a thoracic approach. The thoracic duct is a critical component of the lymphatic system, serving as the primary channel for lymph fluid, which is essential for immune function and fluid balance in the body. It typically originates in the abdomen at the cisterna chyli, located near the second lumbar vertebra, and ascends through the thoracic cavity, crossing from the right side to the left at the level of the fourth or fifth thoracic vertebra before draining into the left jugular-subclavian venous junction. Due to its delicate structure, the thoracic duct is vulnerable to injury, which can result in lymphatic leaks. This procedure is performed to repair such leaks, which may occur due to surgical trauma or other injuries. The surgical approach is determined by the location of the injury, and the procedure involves careful dissection to expose the duct, locate the site of the leak, and perform the necessary repairs using sutures or ligation. Following the repair, additional measures, such as the placement of gauze pads and chest tubes, are taken to ensure proper healing and to monitor for any further leakage.

1. Indications

The procedure is indicated for the following conditions:

  • Lymphatic Leak - This procedure is performed when there is a suspected or confirmed leak in the thoracic duct, which can occur due to surgical trauma or other injuries.
  • Thoracic Duct Injury - Indicated in cases where the thoracic duct has been compromised, necessitating surgical intervention to prevent complications associated with lymphatic fluid accumulation.

2. Procedure

The procedure involves several critical steps to ensure the successful suture and/or ligation of the thoracic duct.

  • Step 1: Surgical Approach - The procedure begins with the selection of the appropriate surgical approach based on the location of the thoracic duct injury. For a thoracic approach, a thoracotomy is performed, which involves making an incision in the chest wall to access the thoracic cavity.
  • Step 2: Exposure of the Thoracic Duct - Once the thoracotomy is completed, the surgeon carefully dissects the soft tissues to expose the thoracic duct. This step is crucial for visualizing the duct and identifying the site of the lymphatic leak.
  • Step 3: Identification of the Leak - The surgeon locates the specific site of the leak within the thoracic duct. This may involve careful inspection and possibly the use of contrast agents to visualize the lymphatic fluid.
  • Step 4: Repair of the Leak - After identifying the leak, the surgeon repairs the injury by suturing the duct or ligating it a few centimeters above and below the site of the leak. This step is essential to restore the integrity of the thoracic duct and prevent further lymphatic fluid loss.
  • Step 5: Post-Repair Care - Following the repair, a dry gauze pad is placed over the site to monitor for any continuing leakage. The gauze is later removed, and the repair may be reinforced with a spray or glue-type sealant to ensure a secure closure.
  • Step 6: Placement of Chest Tubes - After the repair is completed, chest tubes are placed to facilitate drainage and prevent fluid accumulation in the thoracic cavity, which is a common post-operative consideration.

3. Post-Procedure

Post-procedure care involves monitoring the surgical site for any signs of leakage or complications. The patient will typically be observed for a period to ensure that the repair is holding and that there are no adverse effects from the surgery. The presence of chest tubes will require careful management to ensure proper drainage and to prevent any build-up of fluid in the thoracic cavity. Follow-up imaging may be necessary to confirm the success of the repair and to assess the integrity of the thoracic duct. The recovery process will vary depending on the individual patient's condition and the extent of the surgery performed.

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).
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.
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).
