Official Description

Colectomy, total, abdominal, with proctectomy; with continent ileostomy

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 44156 refers to a total colectomy performed through an abdominal approach, which includes the removal of the entire colon along with a proctectomy, and the creation of a continent ileostomy. This surgical procedure is indicated for patients with various conditions affecting the colon and rectum, necessitating the complete removal of these structures. The term 'continent ileostomy' signifies that a surgically constructed internal pouch is created to collect stool, allowing for controlled evacuation by the patient. The procedure begins with a midline abdominal incision, through which the abdominal cavity is accessed and inspected. The entire colon is mobilized by carefully dividing its attachments and separating it from surrounding structures. The mesentery, which is the tissue that supports the colon, is also divided to facilitate the removal of the colon. Following the mobilization, the rectum is addressed, involving the identification and dissection of the superior rectal vessels, which are then ligated and divided. The procedure culminates in the creation of a reservoir from a segment of the ileum, which is designed to function as a storage pouch for fecal matter, allowing the patient to manage bowel movements more effectively. This complex surgical intervention requires meticulous technique and careful postoperative management to ensure optimal recovery and function of the newly created ileostomy.

1. Indications

The procedure described by CPT® Code 44156 is indicated for patients with specific gastrointestinal conditions that necessitate the removal of the colon and rectum. These indications may include:

  • Colorectal cancer: Malignancies affecting the colon or rectum that require surgical intervention to prevent metastasis or alleviate symptoms.
  • Inflammatory bowel disease: Conditions such as ulcerative colitis or Crohn's disease that result in severe inflammation, complications, or unmanageable symptoms.
  • Familial adenomatous polyposis: A genetic disorder characterized by the development of numerous polyps in the colon, which have a high risk of turning cancerous.
  • Severe diverticulitis: Complications arising from diverticulitis that may lead to perforation, abscess formation, or significant bleeding.

2. Procedure

The procedure for CPT® Code 44156 involves several critical steps, each essential for the successful completion of the total colectomy with proctectomy and the creation of a continent ileostomy:

  • Step 1: A midline abdominal incision is made to access the abdominal cavity. This incision allows the surgeon to inspect the abdominal organs and assess the extent of the disease.
  • Step 2: The entire colon is mobilized by dividing the lateral peritoneal attachments and separating the omentum from the transverse colon. This step is crucial for freeing the colon from its surrounding structures.
  • Step 3: The mesentery of the colon is divided, starting from the left colon and continuing proximally. This dissection is necessary to ensure complete removal of the colon.
  • Step 4: The bowel is divided in the ileum, just proximal to the ileocecal valve, marking the point where the small intestine is separated from the colon.
  • Step 5: Attention is then directed to the rectum, where the superior rectal vessels are located, dissected from the sacral promontory, ligated, and divided to facilitate rectal removal.
  • Step 6: The ureters are identified and protected during the dissection, and the peritoneum is incised to access the presacral space.
  • Step 7: Dissection is carried down to the pelvic floor, and an elliptical incision is made around the anus to free the rectum from surrounding tissue.
  • Step 8: The entire colon and rectum are removed from the body, completing the resection.
  • Step 9: The perineal incision is closed in layers to ensure proper healing.
  • Step 10: A segment of ileum, approximately 45 to 60 cm, is mobilized to create a continent ileostomy. This segment is folded back on itself, opened, and sutured to form a reservoir or pouch.
  • Step 11: The distal segment of ileum, approximately 15 cm, is left to create an ileal valve. Electrocautery is used to scarify this segment, which is then telescoped into the reservoir to form the valve.
  • Step 12: The pouch is sutured closed, and the distal end of the ileum is brought through the abdominal wall at the prepared stoma site, sutured flush with the skin.
  • Step 13: A large-diameter plastic tube is placed in the stoma and remains in place for several weeks to facilitate pouch expansion.
  • Step 14: The tube is occluded for progressively longer periods until the patient can tolerate occlusion for up to 8 hours, at which point the tube is removed.
  • Step 15: The patient is instructed to intubate the pouch through the ileal stoma several times a day to drain fecal matter from the reservoir.

3. Post-Procedure

Post-procedure care following a total colectomy with proctectomy and continent ileostomy creation involves several important considerations. Patients will typically require monitoring for complications such as infection, bleeding, or bowel obstruction. Pain management is also a critical aspect of recovery, as patients may experience discomfort from the surgical site. The stoma site will need regular care to ensure proper healing and function. Patients will be educated on how to manage their new ileostomy, including how to intubate the pouch and drain fecal matter effectively. Follow-up appointments will be necessary to assess the healing process and the function of the ileostomy, as well as to provide ongoing support and education regarding dietary adjustments and lifestyle changes that may be needed post-surgery. Overall, a multidisciplinary approach involving surgeons, nurses, and dietitians is essential for optimal recovery and adaptation to the changes following this extensive surgical procedure.

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

96548 Add On Code MPFS Status: Active Code APC N Intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) procedure, including separate incision(s) and closure, when performed; each additional 30 minutes (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.
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.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
