ICD-10-PCS Code For Large Intestine Left: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0DMG includes procedures performed to reattach gastrointestinal structures in the left large intestine. These ICD-10-PCS codes are used for inpatient documentation when a portion of the left large intestine has been separated and requires reattachment to restore continuity or suitable positioning. Accurate coding within the ICD-10-PCS 0DMG group is essential for proper inpatient reimbursement, as it captures the specific reattachment procedure performed and supports clinical documentation accuracy.

Typical Clinical Scenarios

A middle-aged patient presents emergently after blunt abdominal trauma with signs of peritonitis and imaging showing a transection of the left colon with separation of a segment. In the operating room the surgical team performs an open reattachment of the separated left large intestine to restore continuity and control contamination. This inpatient operation addresses the acute loss of bowel continuity due to traumatic separation. Typical codes: 0DMG0ZZ
An older adult with a chronic diverticular disease develops a contained fistula and segmental ischemia of the distal transverse and left colon, resulting in a planned operative session to resect nonviable tissue and reestablish colonic continuity. After resection and assessment, the surgeon performs a percutaneous endoscopic-assisted reattachment of the remaining left large intestine to restore bowel continuity in a controlled inpatient setting. This elective approach minimizes laparotomy in a patient with multiple comorbidities. Typical codes: 0DMG4ZZ
A patient who previously underwent left-sided colectomy with diversion returns with a separated anastomosis and persistent ostomy-related complications; after stabilization and optimization, surgery is undertaken to reunite the separated left colon segments and restore continuity. Because dense adhesions and prior surgery are present, the operation is performed open to safely mobilize and reattach the left large intestine. This inpatient revision procedure corrects a failed or disrupted prior reconstruction. Typical codes: 0DMG0ZZ
