Official Description

Ileoscopy, through stoma; with placement of endoscopic stent (includes pre- and post-dilation and guide wire passage, when performed)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An ileoscopy is a medical procedure that involves the examination of the ileum, which is the final section of the small intestine, through an existing stoma, typically created for patients who have undergone surgery for conditions affecting the bowel. This procedure is performed using an endoscope, a flexible tube equipped with a camera and light, allowing for direct visualization of the ileal mucosa. During the ileoscopy, the physician can assess the condition of the ileum, particularly in cases where there may be strictures or narrowing of the intestinal lumen. The procedure includes the placement of an endoscopic stent, which is a tube-like device used to keep the narrowed segment of the ileum open, facilitating the passage of intestinal contents. The process also involves pre- and post-dilation techniques, which are essential for preparing the stricture for stent placement. Pre-dilation may involve the use of a guidewire and a series of rigid tubes or a balloon catheter to expand the narrowed area, ensuring that the stent can be properly positioned and deployed. This comprehensive approach not only aids in the immediate management of strictures but also helps in improving the overall function of the gastrointestinal tract.

1. Indications

The ileoscopy with endoscopic stent placement is indicated for patients experiencing specific gastrointestinal conditions that may lead to narrowing of the ileum. These indications include:

  • Strictures - Narrowing of the ileum due to various causes such as inflammatory bowel disease, previous surgeries, or radiation therapy.
  • Obstruction - Partial or complete blockage of the ileum that may require intervention to restore normal bowel function.
  • Stenosis - A significant narrowing of the intestinal lumen that can lead to symptoms such as abdominal pain, bloating, and changes in bowel habits.

2. Procedure

The procedure of ileoscopy with endoscopic stent placement involves several critical steps to ensure effective treatment of the narrowed segment of the ileum. These steps include:

  • Insertion of the Endoscope - The procedure begins with the insertion of the endoscope through the ileostomy opening into the ileum. This allows the physician to visualize the intestinal mucosa directly.
  • Inflation of the Ileum - A small amount of air is introduced into the ileum to expand the mucosal folds. This inflation enhances visibility and allows for a thorough inspection of the mucosa.
  • Assessment of Stenosis - The endoscope is advanced along the ileum to locate the area of stenosis. The physician evaluates the position and length of the stricture to determine the appropriate intervention.
  • Pre-Dilation - If pre-dilation is deemed necessary, a guidewire is inserted through the endoscope. Rigid tubes of increasing diameter or a balloon catheter is then passed over the guidewire to dilate the stricture, facilitating the placement of the stent.
  • Stent Placement - Following dilation, a guidewire is again passed through the endoscope, followed by the stent delivery system. The stent is positioned in the narrowed portion of the ileum and deployed, ensuring it is properly expanded to maintain patency.
  • Verification of Stent Position - After deployment, the endoscope is advanced through the stent to confirm its correct position and ensure that it has been properly seated. This step is crucial for the effectiveness of the stent in preventing future obstructions.
  • Withdrawal of the Endoscope - Finally, the endoscope is carefully withdrawn from the ileum, completing the procedure.

3. Post-Procedure

After the ileoscopy with stent placement, patients may require monitoring for any immediate complications such as bleeding or perforation. Post-procedure care typically includes instructions on dietary modifications and signs of potential complications to watch for, such as abdominal pain or changes in bowel habits. Follow-up appointments may be scheduled to assess the effectiveness of the stent and the condition of the ileum, ensuring that the patient’s gastrointestinal function is restored and maintained.

50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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).
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.
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.)
