Official Description

Enterectomy, resection of small intestine; with enterostomy

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 44125 involves an enterectomy, which is a surgical operation that entails the resection or removal of a portion of the small intestine. This procedure is performed in conjunction with the creation of an enterostomy, a surgical opening that allows the small intestine to be brought to the surface of the abdomen. The operation begins with the physician making a midline incision in the abdominal cavity to gain access to the internal organs. During the surgery, any adhesions—abnormal fibrous bands that may bind organs together—are carefully lysed, or cut, using both blunt and sharp dissection techniques. The surgeon then inspects the abdominal contents, including vital organs such as the liver and gallbladder, to assess the extent of the disease affecting the small intestine. Once the diseased segment of the small intestine is identified, it is meticulously dissected away from the surrounding tissues. Blood vessels supplying the affected area are clamped and ligated with sutures to prevent excessive bleeding. The small intestine is then divided, typically using staples or noncrushing clamps, to remove the diseased section. After excising the affected portion, the remaining distal segment of the intestine is closed off, while the proximal segment is prepared for exteriorization through the abdominal wall. To create the enterostomy, a small incision is made at the predetermined site on the abdomen, and the incision is deepened through the subcutaneous tissue. Any excess fat is excised to expose the anterior rectus fascia, which is then opened. The rectus muscle fibers are separated using blunt dissection to allow access to the peritoneum. An opening of adequate size is created in the peritoneum to facilitate the passage of the small bowel segment. The segment of the small intestine that is to be exteriorized is brought through this opening, everted, and sutured securely to the skin, establishing a stoma that allows for the passage of intestinal contents outside the body.

1. Indications

The procedure described by CPT® Code 44125 is indicated for various conditions affecting the small intestine. These may include:

  • Intestinal Obstruction - A blockage in the small intestine that prevents the normal passage of contents.
  • Intestinal Ischemia - A condition where blood flow to a section of the intestine is reduced, leading to tissue damage.
  • Malignancy - The presence of cancerous tumors within the small intestine that necessitate removal.
  • Diverticulitis - Inflammation or infection of diverticula in the intestinal wall, which may require surgical intervention.
  • Congenital Anomalies - Birth defects affecting the structure of the small intestine that may require surgical correction.

2. Procedure

The procedure for CPT® Code 44125 involves several critical steps to ensure the successful resection of the small intestine and the creation of an enterostomy. Each step is performed with precision to minimize complications and promote recovery.

  • Step 1: Midline Incision - The surgeon begins by making a midline incision in the abdominal wall to access the abdominal cavity. This incision allows for optimal exposure of the internal organs and the small intestine.
  • Step 2: Lysis of Adhesions - Once the abdominal cavity is open, the surgeon identifies and lyses any adhesions that may be present. This is done using both blunt and sharp dissection techniques to free the small intestine from surrounding tissues and organs.
  • Step 3: Inspection of Abdominal Contents - The surgeon inspects the abdominal contents, including the liver and gallbladder, to assess the overall condition and identify the diseased section of the small intestine.
  • Step 4: Dissection of Diseased Segment - The diseased portion of the small intestine is carefully dissected free from surrounding tissues. This step is crucial to ensure that the affected area is completely removed without damaging adjacent structures.
  • Step 5: Clamping and Ligation of Blood Vessels - Blood vessels supplying the diseased segment are clamped and ligated with sutures to control bleeding during the resection process.
  • Step 6: Division of the Small Intestine - The small intestine is divided using staples or noncrushing clamps, allowing for the removal of the diseased section while preserving the integrity of the remaining intestine.
  • Step 7: Closure of Distal Segment - The remaining distal segment of the small intestine is closed off to prevent any leakage of intestinal contents.
  • Step 8: Preparation for Enterostomy - The proximal segment of the intestine is prepared for exteriorization. A small incision is made at the planned enterostomy site, and the incision is deepened through the subcutaneous tissue.
  • Step 9: Exposure of Rectus Fascia - The surgeon excises any excess fat to expose the anterior rectus fascia, which is then opened to access the underlying muscle layers.
  • Step 10: Separation of Rectus Muscle Fibers - The rectus muscle fibers are separated using blunt dissection to create a pathway to the peritoneum.
  • Step 11: Creation of Peritoneal Opening - An opening of sufficient diameter is created in the peritoneum to allow for the passage of the small bowel segment.
  • Step 12: Exteriorization of Small Bowel Segment - The segment of small bowel designated for exteriorization is brought through the peritoneum and abdominal wall, everted, and then sutured securely to the skin, establishing the enterostomy.

3. Post-Procedure

After the completion of the procedure, the patient will require careful monitoring and post-operative care. This includes managing the enterostomy site to prevent infection and ensuring proper healing. Patients may need education on stoma care and dietary modifications to accommodate the changes in their digestive system. Follow-up appointments will be necessary to assess recovery and address any complications that may arise. The expected recovery time can vary based on the individual’s overall health and the extent of the surgery performed.

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.
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).
