Official Description

Repair, paraesophageal hiatal hernia, (including fundoplication), via thoracoabdominal incision, 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 condition where the upper part of the stomach, known as the fundus, protrudes into the chest cavity alongside the esophagus while the gastroesophageal junction remains in its normal position. This type of hernia can lead to various complications, including obstruction or strangulation of the stomach. The repair of a paraesophageal hiatal hernia, specifically through a thoracoabdominal incision, is a surgical procedure that addresses this condition effectively. This approach is particularly indicated for patients who have undergone previous surgeries for diaphragmatic hernias or those with hernias that cannot be reduced manually. The procedure involves a combination of thoracic and abdominal incisions to provide adequate access to the affected areas. During the surgery, the herniated stomach is repositioned back into the abdominal cavity, and if necessary, a fundoplication may be performed to prevent future reflux. This procedure is performed without the use of mesh or other prosthetic materials, distinguishing it from similar procedures that may involve such implants. The careful dissection and repair of the diaphragm and esophagus are critical components of this surgical intervention, ensuring both the immediate correction of the hernia and the long-term stability of the anatomical structures involved.

1. Indications

The repair of a paraesophageal hiatal hernia via thoracoabdominal incision is indicated for the following conditions:

  • Paraesophageal Hiatal Hernia - Characterized by the abnormal positioning of the stomach's fundus into the thoracic cavity while the gastroesophageal junction remains in place.
  • Previous Diaphragmatic Hernia Surgery - Patients who have a history of prior surgical interventions for diaphragmatic hernias may require this approach for effective repair.
  • Irreducible Hernia - Cases where the hernia cannot be manually reduced, necessitating surgical intervention to correct the anatomical displacement.

2. Procedure

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

  • Step 1: Incision - A left posterolateral thoracotomy is performed to access the esophagus, while an upper abdominal incision is made to expose the diaphragm and stomach. This dual approach allows for simultaneous access to both the thoracic and abdominal cavities.
  • Step 2: Dissection - Surgeons perform dissection in both the upper abdomen and left chest, carefully dividing any adhesions that may be present. This step is crucial for gaining clear visibility and access to the hernia sac and surrounding structures.
  • Step 3: Identification of Structures - The paraesophageal hernia sac, the muscular origins of the diaphragm (crura), and the esophageal hiatus are identified. If a previous fundoplication has been performed, it is taken down to facilitate the repair.
  • Step 4: Mobilization - The herniated portion of the stomach is mobilized and returned to its proper position within the abdominal cavity. Care is taken to protect the anterior vagus nerve during this process.
  • Step 5: Hernia Sac Excision - The hernia sac is excised to prevent future complications associated with the hernia.
  • Step 6: Fundoplication (if applicable) - If a fundoplication is indicated, the fundus of the stomach is wrapped around the esophagus and sutured to the muscle layer of the stomach and/or esophagus. Various techniques may be employed, including Nissen or Toupet procedures for a complete wrap, or Belsey IV or Belsey Mark IV (BMIV) for a partial wrap.
  • Step 7: Diaphragm Repair - The diaphragm is repaired using sutures, or it may be reinforced with mesh or other prosthetic material if indicated in a different procedure (CPT® Code 43337).
  • Step 8: Closure - Finally, the abdomen and thorax are closed, and chest tubes are placed as needed to facilitate drainage and prevent complications.

3. Post-Procedure

Post-procedure care for patients undergoing repair of a paraesophageal hiatal hernia typically includes monitoring for complications such as infection, bleeding, or respiratory issues due to the thoracic approach. Patients may require pain management and will be advised on activity restrictions during the recovery period. Follow-up appointments are essential to assess healing and ensure that the hernia repair is successful. Additionally, patients may be educated on dietary modifications to prevent complications related to reflux or other gastrointestinal issues following the surgery.

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).
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.)
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).
