Official Description

Gastrointestinal reconstruction for previous esophagectomy, for obstructing esophageal lesion or fistula, or for previous esophageal exclusion; with colon interposition or small intestine reconstruction, including intestine mobilization, preparation, and anastomosis(es)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 43361 refers to a complex surgical procedure known as gastrointestinal reconstruction, specifically performed following a previous esophagectomy. This procedure is indicated for patients who have obstructing esophageal lesions, fistulas, or have undergone esophageal exclusion. The reconstruction can involve the use of either a section of the colon or the small intestine, which is selected based on the specific clinical scenario and the surgeon's assessment. The procedure entails several critical steps, including the mobilization and preparation of the intestine or colon, as well as the creation of anastomoses, which are surgical connections between the segments of the gastrointestinal tract. The complexity of the procedure is underscored by the need to preserve blood supply to the graft, ensuring adequate perfusion, and the potential requirement for additional surgical interventions, such as enlarging the thoracic inlet or performing a median sternotomy, to facilitate access to the anastomosis site. Overall, this procedure aims to restore gastrointestinal continuity and function in patients who have experienced significant esophageal pathology.

1. Indications

The procedure described by CPT® Code 43361 is indicated for the following conditions:

  • Obstructing Esophageal Lesion - This refers to any blockage within the esophagus that prevents normal swallowing and passage of food.
  • Fistula - An abnormal connection between the esophagus and another structure, which can lead to complications such as aspiration or infection.
  • Previous Esophageal Exclusion - This condition arises when the esophagus has been surgically removed or bypassed due to disease or injury, necessitating reconstruction to restore gastrointestinal function.

2. Procedure

The procedure involves several detailed steps to ensure successful gastrointestinal reconstruction:

  • Preparation of the Graft - The choice of graft, either colon or small intestine, is determined based on the patient's specific needs. If a section of colon is selected, the omentum is dissected off the colon to prepare it for use as a graft.
  • Mobilization of the Colon - For a left colon interposition graft, the middle colic artery is ligated, and both the left and right flexures of the colon are mobilized. Care is taken to preserve the arterial and venous collateral circulation to ensure adequate blood flow to the graft.
  • Harvesting the Graft - In some cases, a section of the left colon may be harvested along with the ascending colon. This involves taking down the right flexure and ligating the middle and right colic arteries while preserving the left colic artery for graft perfusion.
  • Measuring the Graft Length - The required length of the colon graft is determined by tethering the colon upward into the chest or neck area and measuring the distance to the planned anastomosis site.
  • Preparation of the Anastomosis Site - The proximal anastomosis site in the chest or neck is prepared. If the anastomosis is to be made in the distal esophagus, it may be necessary to enlarge the thoracic inlet by removing parts of the manubrium, the medial end of the first rib, and the sternal head of the left clavicle. For anastomosis in the middle third of the esophagus, a median sternotomy is performed to access the site.
  • Transection and Placement of the Graft - The colon is then transected, and the graft is placed in a bowel bag to protect it as it is passed through the substernal tunnel to the anastomosis site. The esophagus is divided at this point.
  • Anastomosis of the Graft - The esophagus and colon graft are anastomosed, with the colon graft being sutured to the left crus of the diaphragm or at the diaphragm's opening into the substernal tunnel. The distal end of the colon graft is then anastomosed to the posterior surface of the stomach.
  • Restoration of Colon Continuity - Finally, the remaining segments of the colon, both distal and proximal to the harvested segment, are anastomosed to restore continuity of the gastrointestinal tract.
  • Placement of Jejunostomy Tube - A jejunostomy tube is placed for feeding and decompression, ensuring that the patient can receive nutrition post-operatively.

3. Post-Procedure

Post-procedure care involves monitoring the patient for complications and ensuring proper recovery. Patients may require nutritional support through the jejunostomy tube until they can resume normal oral intake. Close observation for signs of infection, anastomotic leaks, or other complications is essential. Follow-up imaging or endoscopy may be necessary to assess the integrity of the anastomosis and the overall function of the gastrointestinal tract. The recovery process may vary based on the individual patient's condition and the extent of the surgical intervention.

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.
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.
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).
