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 0DBB includes procedures performed to excise portions of the ileum in the gastrointestinal system. These ICD-10-PCS codes are used for inpatient documentation when a portion of the ileum is surgically removed for treatment of disease, obstruction, ischemia, or injury. Accurate coding within the ICD-10-PCS 0DBB group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Ileum Excision Procedure Overview

This procedure group encompasses excision procedures performed on the ileum within the gastrointestinal system. These procedures involve cutting out or off a portion of the ileum without replacement and typically address diseased, damaged, or obstructive segments. Accurate coding of ileum excisions ensures inpatient records reflect the surgical intervention performed and supports appropriate reimbursement and case mix assignment.

Typical Clinical Scenarios

An adult patient presents to the emergency department with acute abdominal pain, fever, and leukocytosis. Imaging demonstrates a segment of necrotic ileum from mesenteric ischemia with perforation and localized peritonitis; the surgical team performs an open laparotomy and excises the nonviable ileal segment without immediate reconstruction. An open excision code from the group is used to report removal of the diseased ileum portion. Typical codes: 0DBB0ZZ
A middle-aged patient with Crohn disease refractory to medical therapy is admitted for a planned elective limited ileal resection to remove a chronically inflamed, strictured segment causing obstructive symptoms. The surgeon performs the planned excision of the affected ileum via a minimally invasive percutaneous endoscopic approach without placement of a graft or prosthesis. A percutaneous endoscopic excision code from the group is appropriate for this elective procedure. Typical codes: 0DBB4ZZ
An elderly patient with a history of prior small bowel surgery develops recurrent small-bowel obstruction due to adhesions and a discrete segment of diseased ileum identified at exploratory minimally invasive surgery. The procedure involves percutaneous excision of the problematic ileal segment for symptom relief and to prevent further obstruction; no replacement is inserted. A percutaneous excision code best represents this complication-related operative intervention. Typical codes: 0DBB3ZZ
