Official Description

Colonoscopy, flexible; with removal of foreign body(s)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A flexible colonoscopy is a diagnostic and therapeutic procedure that involves the insertion of a colonoscope into the rectum and advancement through the colon to the cecum or the terminal ileum. This procedure is specifically performed for the removal of foreign body(s) that may be lodged within the colon. During the colonoscopy, air insufflation is utilized to expand the colon, allowing for improved visualization of the mucosal surfaces. The physician inspects these surfaces meticulously to locate the foreign body. Various techniques may be employed for the removal of the foreign body, including the use of a balloon catheter for smooth-edged objects or forceps for impacted items. The balloon catheter technique involves passing the catheter tip beyond the foreign body, inflating the balloon, and then withdrawing the catheter to extract the foreign body. In cases where the foreign body is impacted, forceps are introduced through the endoscope to grasp and remove the object. After the removal process, the colonoscope is reintroduced to conduct a thorough examination of the colon for any signs of perforation or other potential injuries that may have occurred during the procedure.

1. Indications

The flexible colonoscopy with removal of foreign body(s) is indicated in specific clinical scenarios where a foreign object is suspected to be lodged within the colon. The following conditions may warrant this procedure:

  • Foreign Body Ingestion: Patients who have ingested objects that may pass through the gastrointestinal tract but have become lodged in the colon.
  • Symptoms of Obstruction: Patients presenting with symptoms such as abdominal pain, distension, or changes in bowel habits that suggest a blockage due to a foreign body.
  • Previous Imaging Findings: Imaging studies indicating the presence of a foreign body within the colon that requires removal.

2. Procedure

The procedure for a flexible colonoscopy with removal of foreign body(s) involves several critical steps to ensure successful extraction and patient safety:

  • Step 1: Preparation and Anesthesia The patient is positioned appropriately, and sedation or anesthesia is administered to ensure comfort during the procedure. The colon is prepared through bowel cleansing protocols prior to the colonoscopy.
  • Step 2: Insertion of the Colonoscope The colonoscope, a flexible tube equipped with a camera and light source, is gently inserted into the rectum. The physician carefully advances the colonoscope through the rectum and into the colon, using air insufflation to expand the colon and enhance visibility of the mucosal surfaces.
  • Step 3: Inspection and Localization Once the colonoscope reaches the cecum or terminal ileum, the physician inspects the mucosal surfaces for any abnormalities, including the presence of foreign body(s). The location of the foreign body is identified during this inspection.
  • Step 4: Removal of Foreign Body Depending on the characteristics of the foreign body, different techniques are employed for removal. For smooth-edged foreign bodies, a balloon catheter may be utilized. The catheter is passed beyond the foreign body, and the balloon is inflated to facilitate removal. For impacted foreign bodies, forceps are introduced through the endoscope to grasp and extract the object.
  • Step 5: Post-Removal Examination After the foreign body has been successfully removed, the colonoscope is reintroduced to conduct a thorough examination of the colon for any signs of perforation or injury that may have occurred during the procedure.

3. Post-Procedure

Following the procedure, patients are monitored for any immediate complications or adverse reactions to sedation. It is essential to assess for signs of perforation or bleeding. Patients may experience mild discomfort or cramping, which typically resolves shortly after the procedure. Instructions regarding diet, activity level, and follow-up care are provided to ensure proper recovery. Any significant findings during the colonoscopy, including the presence of additional abnormalities, should be documented and communicated to the patient for further management.

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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
