Official Description

Ileoscopy, through stoma; with transendoscopic balloon dilation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Ileoscopy is a specialized endoscopic procedure that involves the examination of the ileum, which is the final section of the small intestine, through an existing stoma, specifically an ileostomy. This procedure is performed using an endoscope, a flexible tube equipped with a camera and light source, which is inserted into the ileum via the stoma. The primary purpose of ileoscopy is to visualize the mucosal lining of the ileum, allowing for the assessment of any abnormalities or conditions affecting this part of the digestive tract. During the procedure, the ileum is inflated with a small amount of air to expand the mucosal folds, enhancing visibility for the physician. This inflation aids in the thorough inspection of the mucosa for any signs of disease or damage. Additionally, ileoscopy can involve obtaining tissue samples through biopsy or collecting cell samples via brushing or washing techniques. A critical component of this procedure is the transendoscopic balloon dilation, which is performed when a narrowed area, or stricture, of the ileum is identified. This dilation process involves the use of a balloon device that is inserted through the endoscope to widen the narrowed segment, thereby improving the passage through the ileum. The combination of these techniques during ileoscopy allows for both diagnostic and therapeutic interventions, making it a valuable procedure in managing conditions affecting the ileum.

1. Indications

The ileoscopy procedure is indicated for various conditions and symptoms that may affect the ileum, particularly when there is a need for direct visualization and intervention. The following are explicitly provided indications for performing ileoscopy:

  • Evaluation of Ileal Strictures - This procedure is often performed to assess and treat narrowed areas of the ileum, which can lead to obstruction and other complications.
  • Investigation of Inflammatory Bowel Disease - Ileoscopy is indicated for patients with suspected or known inflammatory bowel diseases, such as Crohn's disease, to evaluate the extent of disease involvement.
  • Assessment of Tumors or Polyps - The procedure may be indicated for the identification and biopsy of tumors or polyps located in the ileum.
  • Surveillance of Post-Surgical Changes - Patients who have undergone previous surgeries involving the ileum may require ileoscopy to monitor for any complications or changes in the ileal structure.

2. Procedure

The ileoscopy procedure involves several key steps that ensure effective examination and treatment of the ileum. The following procedural steps are explicitly described:

  • Step 1: Preparation and Anesthesia - The patient is prepared for the procedure, which may include fasting and the administration of sedation or anesthesia to ensure comfort during the examination.
  • Step 2: Insertion of the Endoscope - The endoscope is carefully inserted through the ileostomy opening into the ileum. The physician navigates the scope to reach the area of interest while ensuring minimal discomfort to the patient.
  • Step 3: Inflation of the Ileum - A small amount of air is introduced into the ileum to inflate it. This inflation helps to expand the mucosal folds, providing better visualization of the ileal lining.
  • Step 4: Inspection of the Mucosa - The physician systematically inspects the mucosal surface of the ileum for any abnormalities, such as inflammation, lesions, or strictures.
  • Step 5: Collection of Samples - If necessary, cell samples may be obtained through brushing or washing saline fluid into the ileum. Additionally, biopsy forceps can be introduced through the endoscope to collect tissue samples from identified areas for further analysis.
  • Step 6: Balloon Dilation - If a stricture is identified, a balloon catheter is advanced through the endoscope to the narrowed area. The balloon is inflated using a pressure gauge to determine the optimal inflation level, which is maintained for a short duration (30 seconds to 2 minutes) to effectively dilate the stricture.
  • Step 7: Post-Dilation Inspection - After the balloon is deflated and removed, the physician inspects the area of dilation to confirm the success of the procedure and to check for any potential injuries to the ileum.

3. Post-Procedure

Following the ileoscopy procedure, patients may experience some discomfort or cramping, which is typically mild and resolves quickly. It is important for patients to be monitored for any immediate complications, such as bleeding or perforation. The physician may provide specific post-procedure care instructions, including dietary recommendations and activity restrictions. Patients are usually advised to gradually resume their normal diet and activities as tolerated. Additionally, any collected tissue or cell samples will be sent for laboratory analysis, and results will be discussed with the patient in a follow-up appointment. It is essential for patients to report any unusual symptoms, such as severe pain or persistent bleeding, to their 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.
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.
GC This service has been performed in part by a resident under the direction of a teaching physician
GW Service not related to the hospice patient's terminal condition
PT Colorectal cancer screening test; converted to diagnostic test or other procedure
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
