Official Description

Gastrointestinal tract imaging, intraluminal (eg, capsule endoscopy), colon, with interpretation and report

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 91113 involves gastrointestinal tract imaging using an intraluminal device, specifically a capsule endoscopy. This innovative technique utilizes a small, disposable capsule that contains a miniature endoscope equipped with a camera. The complete system also includes sensing and transmission devices, along with a data recorder that the patient wears. The primary purpose of this procedure is to obtain detailed images of the colon, particularly in cases where traditional colonoscopy has proven to be technically impossible, or when there has been incomplete fecal evacuation or issues with bowel preparation. During the procedure, the patient swallows the capsule, which then travels through the gastrointestinal tract propelled by natural peristaltic movements. As the capsule moves, it captures images of the colon at two-second intervals. These images are wirelessly transmitted to a recorder worn around the patient's waist. After the imaging process is complete, which typically occurs within approximately 24 hours, the collected data is downloaded to a workstation computer for thorough interpretation. A comprehensive report detailing the findings is then generated, providing valuable insights into the condition of the colon, including the detection of polyps and tumors.

1. Indications

The procedure is indicated for the following conditions:

  • Technical impossibility of colonoscopy - When a standard colonoscopy cannot be performed due to anatomical or technical challenges.
  • Incomplete fecal evacuation - In cases where the bowel preparation is inadequate, preventing a thorough examination during colonoscopy.
  • Problematic bowel preparation - Situations where the preparation for colonoscopy does not allow for clear visualization of the colon.

2. Procedure

The procedure involves several key steps to ensure effective imaging of the colon:

  • Step 1: Patient Preparation - Prior to the procedure, the patient is instructed on how to prepare for the capsule endoscopy. This may include dietary restrictions and guidelines for bowel preparation to optimize the imaging results.
  • Step 2: Capsule Ingestion - The patient swallows the capsule, which is designed to travel through the gastrointestinal tract. The capsule is small and equipped with a camera that captures images as it moves.
  • Step 3: Image Capture - As the capsule progresses through the colon, it takes pictures at two-second intervals. This imaging process allows for detailed visualization of the colonic mucosa.
  • Step 4: Data Transmission - The images captured by the capsule are transmitted wirelessly to a data recorder that the patient wears around their waist. This ensures that all images are collected without the need for invasive procedures.
  • Step 5: Data Download and Interpretation - After approximately 24 hours, the capsule is naturally expelled from the body. The recorded data is then downloaded to a workstation computer, where a healthcare professional interprets the images and prepares a report detailing the findings.

3. Post-Procedure

After the capsule endoscopy, the patient can typically resume normal activities immediately. The capsule is expected to be expelled naturally within about 24 hours. Patients may be advised to monitor for any unusual symptoms following the procedure. The healthcare provider will review the interpreted data and findings from the capsule endoscopy, providing a comprehensive report that may guide further diagnostic or therapeutic actions based on the results.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
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).
