Official Description

Suture of small intestine (enterorrhaphy) for perforated ulcer, diverticulum, wound, injury or rupture; single perforation

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Suture repair of the small intestine, known as enterorrhaphy, is a surgical procedure aimed at addressing a perforation in the small intestine caused by various conditions such as ulcers, diverticula, wounds, injuries, or ruptures. This procedure is critical in preventing further complications, such as peritonitis, which can arise from the leakage of intestinal contents into the abdominal cavity. During the surgery, an incision is made in the abdomen to access the affected segment of the small intestine. The surgeon carefully removes the segment that requires repair and places it on the operating table for further manipulation. The intestinal contents are expressed from the segment to ensure a clean working area. To facilitate the repair, the intestine is clamped above and below the perforation, allowing for controlled management of the area. Any bleeding that may occur is addressed through suture ligation of the involved blood vessels. The actual closure of the perforation involves suturing the mucous membranes first, followed by the serous coat, and finally the muscular wall, ensuring a secure and effective repair. After the repair is completed, the abdominal cavity is thoroughly cleansed using gauze and irrigation fluid as necessary to minimize the risk of infection. Drains may be placed if required, and the abdominal incision is then closed. This procedure is specifically coded as CPT® Code 44602 when a single perforation is repaired, while CPT® Code 44603 is used for cases involving multiple perforations.

1. Indications

The suture of the small intestine (enterorrhaphy) is indicated for the following conditions:

  • Perforated Ulcer A perforated ulcer occurs when an ulcer in the intestinal lining creates a hole, allowing intestinal contents to leak into the abdominal cavity.
  • Diverticulum A diverticulum is a small pouch that can form in the wall of the intestine, which may become inflamed or perforated, necessitating surgical intervention.
  • Wound Traumatic wounds to the small intestine can lead to perforation, requiring surgical repair to restore intestinal integrity.
  • Injury Any injury to the small intestine, whether from blunt or penetrating trauma, may result in perforation that requires surgical repair.
  • Rupture A rupture of the small intestine, which can occur due to various pathological conditions, necessitates immediate surgical intervention to prevent serious complications.

2. Procedure

The procedure for enterorrhaphy involves several critical steps to ensure effective repair of the perforation:

  • Step 1: Incision The surgeon begins by making an incision in the abdomen to access the small intestine. This incision allows for direct visualization and manipulation of the affected area.
  • Step 2: Segment Removal The segment of the small intestine that is damaged or perforated is carefully removed from the abdominal cavity and placed on the operating table for further examination and repair.
  • Step 3: Expression of Intestinal Contents The intestinal contents are expressed from the segment to ensure a clean working area, minimizing the risk of contamination during the repair process.
  • Step 4: Clamping The intestine is clamped above and below the perforation to isolate the area and control any potential bleeding, allowing for a focused repair.
  • Step 5: Bleeding Control Any bleeding that occurs is managed through suture ligation of the involved blood vessels, ensuring that the surgical field remains clear and safe for repair.
  • Step 6: Closure of the Perforation The opening in the intestine is closed by suturing the mucous membranes first, followed by the serous coat, and finally the muscular wall, ensuring a secure and effective repair of the perforation.
  • Step 7: Abdominal Cavity Cleansing After the repair is completed, the abdominal cavity is cleansed using gauze and irrigation fluid as needed to reduce the risk of infection.
  • Step 8: Drain Placement If necessary, drains are placed to facilitate the removal of any excess fluid or potential infection from the surgical site.
  • Step 9: Closure of the Incision Finally, the abdominal incision is closed, completing the surgical procedure.

3. Post-Procedure

Post-procedure care following enterorrhaphy includes monitoring for signs of infection, ensuring proper healing of the surgical site, and managing any pain or discomfort. Patients may require a period of recovery in the hospital, during which their vital signs and abdominal status are closely observed. Instructions regarding diet, activity level, and follow-up appointments will be provided to ensure optimal recovery and to address any complications that may arise. It is essential for patients to adhere to the post-operative care plan to promote healing and prevent any adverse outcomes.

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.
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).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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).
