Official Description

Closure of enteroenteric or enterocolic fistula

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 44650 involves the surgical closure of an enteroenteric or enterocolic fistula. An enteroenteric fistula refers to an abnormal connection between two segments of the small intestine, while an enterocolic fistula is an abnormal passage between a segment of the small intestine and a segment of the colon, which is the large intestine. These fistulas can result from various conditions, including inflammatory diseases, infections, or surgical complications. During the procedure, the surgeon makes an incision in the abdomen to access the affected area. The fistulous tract, which is the abnormal passage, is identified and then severed at both ends where it connects to the intestines. After excising the tract, the openings in the intestines are meticulously closed using sutures to restore the integrity of the intestinal walls. Finally, the surgical incision in the abdomen is closed, completing the procedure. This intervention is critical for preventing complications associated with fistulas, such as infection, malnutrition, and bowel obstruction.

1. Indications

The closure of enteroenteric or enterocolic fistulas is indicated in several clinical scenarios where these abnormal connections pose significant health risks. The following conditions may warrant this surgical intervention:

  • Presence of Fistula: The existence of an enteroenteric or enterocolic fistula that has been diagnosed through imaging or clinical evaluation.
  • Infection: The development of infections or abscesses associated with the fistula, which can lead to further complications if not addressed.
  • Malnutrition: Nutritional deficiencies resulting from the abnormal passage of intestinal contents, which can impair the absorption of nutrients.
  • Bowel Obstruction: Symptoms of bowel obstruction that may arise due to the presence of the fistula, necessitating surgical intervention to restore normal bowel function.

2. Procedure

The procedure for closing an enteroenteric or enterocolic fistula involves several critical steps to ensure successful closure and restoration of intestinal integrity. The following outlines the procedural steps:

  • Step 1: The surgeon begins by administering anesthesia to the patient to ensure comfort throughout the procedure. Once the patient is adequately anesthetized, an incision is made in the abdominal wall to access the affected area of the intestine.
  • Step 2: After the abdominal cavity is accessed, the surgeon locates the fistulous tract. This involves careful exploration of the intestines to identify the abnormal connection between the segments of the small intestine or between the small intestine and the colon.
  • Step 3: Once the fistulous tract is identified, the surgeon proceeds to sever the tract at both intestinal openings. This step is crucial as it removes the abnormal passage that has formed between the intestinal segments.
  • Step 4: Following the excision of the fistulous tract, the next step involves closing the openings in the intestines. The surgeon uses sutures to meticulously close these openings, ensuring that the intestinal walls are securely reconnected and that there is no leakage of intestinal contents.
  • Step 5: Finally, the surgical incision in the abdomen is closed. This may involve suturing the layers of the abdominal wall back together, ensuring proper healing and minimizing the risk of infection.

3. Post-Procedure

After the closure of the enteroenteric or enterocolic fistula, patients typically require monitoring in a recovery area to ensure stable vital signs and to manage any immediate post-operative pain. The expected recovery period may vary depending on the individual’s overall health and the complexity of the procedure. Patients are often advised to follow a specific diet and may need to gradually reintroduce foods as tolerated. Follow-up appointments are essential to monitor healing and to assess for any potential complications, such as infection or recurrence of the fistula. Additionally, healthcare providers may provide guidance on activity restrictions during the recovery phase to promote optimal healing.

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.
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.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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.)
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
