Official Description

Laparoscopy, surgical; each additional small intestine resection and anastomosis (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 44203 refers to a laparoscopic surgical procedure involving the resection and anastomosis of each additional segment of the small intestine. This procedure is performed using minimally invasive techniques, which typically involve making small incisions in the abdominal wall. The process begins with the establishment of pneumoperitoneum, allowing the surgeon to visualize the abdominal cavity through a camera inserted via a trocar. The surgeon inspects the abdominal cavity and identifies the segment of the small intestine that requires resection. Following this, the bowel is mobilized, and the resection sites are prepared. The procedure includes clamping and dividing the small intestine at the designated sites, followed by the anastomosis, where the two ends of the intestine are sutured or stapled together. It is important to note that this code is used in conjunction with a primary procedure code, specifically for each additional segment resected and anastomosed, thereby ensuring accurate billing and documentation for the surgical services provided.

1. Indications

The procedure associated with CPT® Code 44203 is indicated for various conditions affecting the small intestine that may require surgical intervention. These indications include:

  • Intestinal Obstruction - A blockage in the small intestine that prevents the normal passage of contents.
  • Intestinal Ischemia - Insufficient blood flow to a segment of the small intestine, 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 small intestine, which may require resection.
  • Congenital Anomalies - Birth defects affecting the structure of the small intestine that may require surgical correction.

2. Procedure

The procedure for CPT® Code 44203 involves several detailed steps, which are as follows:

  • Step 1: Establishing Access - A small portal incision is made near the umbilicus, and a trocar is inserted to establish pneumoperitoneum, which allows for the inflation of the abdominal cavity. Additional portal incisions are made in the upper and lower quadrants of the abdomen, where more trocars are placed to facilitate the procedure.
  • Step 2: Inspection and Mobilization - The abdominal cavity is thoroughly inspected to assess the condition of the small intestine. The segment of the small intestine that is to be resected is identified and mobilized, allowing it to be exteriorized for the surgical intervention.
  • Step 3: Resection Preparation - The distal resection site in the small intestine is identified. The intestine is then clamped and divided at this site to prepare for the resection.
  • Step 4: Exteriorization - The incision at one of the abdominal trocar sites is enlarged to allow the proximal segment of the small intestine to be brought through the incision. This segment is exteriorized beyond the proximal resection site for further manipulation.
  • Step 5: Resection of Proximal Segment - The proximal resection site is identified, and the segment is resected using surgical clips and a harmonic scalpel to ensure precision and minimize bleeding.
  • Step 6: Returning the Intestine - The remaining segment of the exteriorized small intestine is returned to the abdominal cavity, and the incision made for exteriorization is closed securely.
  • Step 7: Anastomosis - The distal and proximal segments of the small intestine are then sutured or stapled together, completing the anastomosis. The small bowel is clamped above and below the segment to be removed, and the intestine is divided at the identified resection sites. Finally, the proximal and distal segments are sutured or stapled together, and the clamps are released to restore continuity of the intestinal tract.

3. Post-Procedure

Post-procedure care following the laparoscopic small intestine resection and anastomosis involves monitoring the patient for any signs of complications, such as infection or leakage at the anastomosis site. Patients are typically advised to follow a specific diet as they recover, gradually transitioning from clear liquids to solid foods as tolerated. Pain management is also an essential aspect of post-operative care, and patients may be prescribed analgesics to manage discomfort. Follow-up appointments are necessary to assess healing and ensure that the patient is recovering appropriately. Any concerns regarding bowel function or other symptoms should be communicated to the healthcare provider promptly.

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).
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.)
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).
