Official Description

Intraoperative colonic lavage (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Intraoperative colonic lavage is a specialized medical procedure aimed at cleansing the colon of fecal matter, which is particularly important prior to conducting a colectomy or colon repair. This procedure is performed during surgery and is essential for ensuring that the surgical field is clear of any obstructive material that could complicate the primary surgical intervention. The process begins with the mobilization of the splenic flexure, allowing the surgeon to effectively manipulate the colon. Manual massage is then employed to move the contents of the colon into the descending colon, facilitating the removal of fecal matter. To aid in this process, a drain is inserted into the descending colon, which serves as an outlet for the evacuated fecal material. An incision is made in the cecum, where a catheter is introduced. This catheter is crucial for delivering an irrigating solution into the colon, which, when combined with the manual massage, helps to break up any solid stool present. The combination of stool and irrigating solution is then expelled from the descending colon through the drain. Once the lavage is completed, the catheter and drain are removed, and the incision in the cecum is closed. Following this preparatory step, the surgeon can proceed with the definitive surgical procedure, ensuring optimal conditions for the operation.

1. Indications

The intraoperative colonic lavage procedure is indicated in specific surgical scenarios where a clear colon is essential for the success of subsequent surgical interventions. The following conditions warrant the performance of this procedure:

  • Colectomy This procedure is often performed prior to a colectomy, which involves the surgical removal of all or part of the colon, to ensure that the surgical field is free of fecal matter.
  • Colon Repair In cases where a repair of the colon is necessary, intraoperative colonic lavage helps to cleanse the colon, reducing the risk of contamination during the repair process.

2. Procedure

The intraoperative colonic lavage procedure consists of several critical steps that ensure effective cleansing of the colon. Each step is designed to facilitate the removal of fecal matter and prepare the colon for subsequent surgical procedures.

  • Step 1: Mobilization of the Splenic Flexure The procedure begins with the mobilization of the splenic flexure, which allows the surgeon to access the colon more effectively. This step is crucial for enabling the manual manipulation of the colon contents.
  • Step 2: Manual Massage Following mobilization, the surgeon performs manual massage of the colon to encourage the movement of fecal matter into the descending colon. This technique is essential for preparing the colon for lavage.
  • Step 3: Insertion of Drain A drain is then inserted into the descending colon. This drain serves as an outlet for the evacuation of fecal material during the lavage process.
  • Step 4: Incision in the Cecum An incision is made in the cecum, which is the beginning of the large intestine. This incision allows for the insertion of a catheter that will facilitate the irrigation process.
  • Step 5: Catheter Insertion A catheter is inserted through the incision in the cecum. This catheter is used to deliver an irrigating solution into the colon.
  • Step 6: Irrigation The irrigating solution is flushed through the catheter into the colon while the colon is massaged. This step is critical for breaking up solid stool and ensuring thorough cleansing.
  • Step 7: Evacuation of Contents The stool and irrigating solution are expelled from the descending colon through the previously placed drain, effectively cleansing the colon.
  • Step 8: Removal of Catheter and Drain Upon completion of the lavage procedure, the catheter and drain are carefully removed. This step is followed by closing the incision in the cecum to ensure proper healing.

3. Post-Procedure

After the intraoperative colonic lavage is completed, the focus shifts to post-procedure care. The incision in the cecum is closed, and the surgical team monitors the patient for any signs of complications. It is essential to ensure that the surgical site is healing properly and that there are no signs of infection or other adverse effects. The patient may be observed for a period to assess recovery and readiness for the subsequent definitive surgical procedure. Proper documentation of the lavage procedure is also critical for coding and billing purposes, as it is reported separately in addition to the primary procedure.

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.
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).
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).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
GC This service has been performed in part by a resident under the direction of a teaching physician
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
