Official Description

Repair, paraesophageal hiatal hernia (including fundoplication), via thoracotomy, except neonatal; without implantation of mesh or other prosthesis

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A paraesophageal hiatal hernia is a specific type of hernia where the gastroesophageal junction remains in its normal anatomical position, but the fundus, which is the upper part of the stomach, protrudes into the thoracic cavity adjacent to the esophagus. This condition can lead to various complications, including obstruction or strangulation of the stomach. The surgical procedure coded as CPT® 43334 involves a repair of this hernia through a thoracotomy, which is an incision made in the chest wall. During the operation, the surgeon mobilizes the stomach and repositions it back into the abdominal cavity. A critical step in this procedure is the creation of a window behind the esophagus, which allows for the proper placement of the stomach. If a fundoplication is indicated, the surgeon wraps the stomach around the esophagus to prevent future reflux and secures it in place with sutures. Techniques such as the Belsey IV or Belsey Mark IV (BMIV) are commonly utilized, which involve a partial wrap of approximately 270 degrees. The hernia sac is carefully excised, and the diaphragm is repaired, either with sutures or reinforced with mesh in a different procedure coded as CPT® 43335. Finally, the thoracic cavity is closed, and chest tubes may be inserted as necessary to facilitate recovery and drainage.

1. Indications

The procedure coded as CPT® 43334 is indicated for patients presenting with a paraesophageal hiatal hernia. This condition may manifest with symptoms such as:

  • Chest Pain Patients may experience discomfort or pain in the chest area due to the herniation of the stomach.
  • Dysphagia Difficulty swallowing can occur as the hernia may compress the esophagus.
  • Gastroesophageal Reflux Disease (GERD) Patients may suffer from acid reflux symptoms, which can be exacerbated by the hernia.
  • Shortness of Breath The protrusion of the stomach into the thoracic cavity can lead to respiratory difficulties.
  • Vomiting Some patients may experience nausea and vomiting, particularly if there is obstruction.

2. Procedure

The surgical procedure for repairing a paraesophageal hiatal hernia via thoracotomy involves several critical steps:

  • Step 1: Incision The surgeon begins by making an incision in the chest wall, typically just above the diaphragm, to access the thoracic cavity.
  • Step 2: Mobilization of the Stomach Once the incision is made, the stomach is carefully mobilized and pulled into the thoracic cavity to allow for proper visualization and access to the hernia.
  • Step 3: Creation of a Window A window is created behind the esophagus, which is essential for repositioning the stomach and performing the fundoplication if indicated.
  • Step 4: Fundoplication (if performed) If a fundoplication is part of the procedure, the surgeon wraps the stomach partially or completely around the esophagus and secures it with sutures to the muscle layer of the fundus and/or esophagus.
  • Step 5: Hernia Sac Management The hernia sac is mobilized with care to protect the anterior vagus nerve, and then it is excised to prevent future complications.
  • Step 6: Diaphragm Repair The diaphragm is repaired using sutures, or in cases where additional support is needed, it may be reinforced with mesh or other prosthetic material, which is coded under CPT® 43335.
  • Step 7: Closure Finally, the thoracic cavity is closed, and chest tubes may be placed as necessary to facilitate drainage and recovery.

3. Post-Procedure

After the procedure, patients are typically monitored for any complications and may require a period of recovery in the hospital. Post-operative care includes managing pain, monitoring for signs of infection, and ensuring proper respiratory function. Patients may also be advised on dietary modifications and activity restrictions during the initial recovery phase to promote healing and prevent complications. Follow-up appointments are essential to assess the surgical site and overall recovery progress.

This is a primary code that can be used with these additional add-on codes.

43338 Addon Code MPFS Status: Active Code APC C Esophageal lengthening procedure (eg, Collis gastroplasty or wedge gastroplasty) (List separately in addition to code for primary procedure)
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).
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).
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.)
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).
