ICD-10-PCS Code For Ileum: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0DMB includes procedures performed to reattach portions of the ileum in the gastrointestinal system. These ICD-10-PCS codes are used for inpatient documentation when surgical reconnection of separated ileal tissue is performed to restore intestinal continuity. Accurate coding within the ICD-10-PCS 0DMB group is essential for proper inpatient reimbursement, as it captures the specific reattachment procedure performed and supports clinical documentation accuracy.

Ileum Reattachment Procedure Overview

Procedures in this group involve reattaching all or a portion of the ileum to restore continuity of the gastrointestinal system following separation or detachment. These reattachment procedures target the gastrointestinal system and typically include surgical reconnection of ileal tissue. Accurate coding of ileum reattachment procedures in inpatient records ensures correct capture of the operative intervention and supports appropriate reimbursement and case mix assignment.

When to Use

Use a code from this group when a surgeon performs reattachment of separated or detached ileal segments to reestablish intestinal continuity. These codes apply when the primary operative intent is reattachment of the ileum rather than procedures such as revision, anastomosis, or bypass.

Typical Clinical Scenarios

An adult presents emergently after blunt abdominal trauma with signs of peritonitis and imaging showing a transected distal ileum with contamination; the patient is taken to the OR for restoration of intestinal continuity after debridement of devitalized ends to prevent ongoing sepsis. A surgical reattachment of the ileal segments is performed to reestablish bowel continuity during the same admission. Typical codes: 0DMB0ZZ.
An elective case in a patient with Crohn disease who previously had an ileal segment exteriorized as a temporary stoma that has since healed and matured; during a planned inpatient admission, the surgeon performs takedown of the stoma and reattaches the ileal limb to restore enteric continuity. The procedure is performed via a minimally invasive endoscopic-guided percutaneous approach in a controlled setting. Typical codes: 0DMB4ZZ.
A patient develops a postoperative disruption of an ileal anastomosis after small bowel resection, resulting in leakage and failure of the prior connection; once stabilized and infection is controlled, the patient returns to the operating room for reoperation to reapproximate and reattach the separated ileal ends to reestablish continuity and heal the fistula. Typical codes: 0DMB0ZZ.
