Official Description

Suture of large intestine (colorrhaphy) for perforated ulcer, diverticulum, wound, injury or rupture (single or multiple perforations); without colostomy

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Suture repair of the large intestine, known as colorrhaphy, is a surgical procedure aimed at addressing various conditions that result in perforations of the large intestine. This procedure is specifically indicated for cases involving perforated ulcers, diverticula, wounds, injuries, or ruptures, which can lead to serious complications if not treated promptly. During the operation, a surgical incision is made in the abdomen to access the affected segment of the large intestine. The surgeon carefully removes the segment that requires repair and places it on the operating table for further manipulation. The contents of the intestine are expressed to ensure a clear working area. To manage the perforation, the intestine is clamped above and below the site of injury, allowing for controlled repair. Any bleeding that may occur is addressed through the suture ligation of the involved blood vessels. The repair itself involves suturing the mucous membranes of the intestine, followed by the serous coat and the muscular wall, ensuring a secure closure. After the repair is completed, the abdominal cavity is thoroughly cleansed using gauze and irrigation fluid as necessary to minimize the risk of infection. Depending on the clinical situation, drains may be placed to facilitate fluid management, and the abdominal incision is subsequently closed. It is important to report CPT® Code 44604 for this suture repair procedure when it is performed without the creation of a colostomy. In contrast, if a colostomy is also performed, CPT® Code 44605 should be reported, which involves additional steps for creating a stoma from the colon.

1. Indications

The suture repair of the large intestine (colorrhaphy) is indicated for the following conditions:

  • Perforated Ulcer A perforated ulcer in the large intestine can lead to leakage of intestinal contents into the abdominal cavity, necessitating surgical intervention.
  • Diverticulum The presence of diverticula, which are small pouches that can form in the intestinal wall, may become inflamed or perforated, requiring repair.
  • Wound Traumatic wounds to the large intestine can result in perforations that need to be surgically repaired to prevent complications.
  • Injury Any injury to the large intestine that causes a perforation may require a colorrhaphy to restore intestinal integrity.
  • Rupture A rupture of the large intestine, which can occur due to various factors, necessitates immediate surgical repair to avoid serious health risks.

2. Procedure

The procedure for suture repair of the large intestine involves several critical steps:

  • Step 1: Incision The surgeon begins by making an incision in the abdomen to access the large intestine. This incision allows for direct visualization and manipulation of the affected area.
  • Step 2: Segment Removal The segment of the large intestine that is damaged or perforated is carefully removed from the abdominal cavity and placed on the operating table for further assessment and repair.
  • Step 3: Expression of Intestinal Contents The contents of the intestinal segment are expressed to ensure a clean working area, which is essential for a successful repair.
  • Step 4: Clamping The intestine is clamped above and below the site of the perforation. This step is crucial as it isolates the area of injury and prevents further leakage of intestinal contents during the repair process.
  • Step 5: Control of Bleeding Any bleeding that occurs during the procedure is controlled through the suture ligation of the involved blood vessels, ensuring that the surgical field remains clear and manageable.
  • Step 6: Suturing the Intestine The opening in the intestine is closed by suturing the mucous membranes first, followed by the serous coat and then the muscular wall, ensuring a secure and watertight closure.
  • Step 7: Cleansing the Abdominal Cavity 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: Placement of Drains Depending on the clinical situation, drains may be placed to facilitate the management of any potential fluid accumulation.
  • Step 9: Closure of the Incision Finally, the abdominal incision is closed, completing the surgical procedure.

3. Post-Procedure

Post-procedure care following a suture repair of the large intestine includes monitoring for any signs of complications such as infection, bleeding, or leakage from the repair site. Patients may require pain management and should be observed for proper recovery of bowel function. Follow-up appointments are essential to assess the healing process and to ensure that the surgical site is recovering as expected. Additional considerations may include dietary modifications and activity restrictions during the initial recovery phase to promote healing and prevent strain on the surgical site.

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

44701 Addon Code MPFS Status: Active Code APC N ASC N1 Illustration for Code Intraoperative colonic lavage (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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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).
