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 0D9B includes procedures performed to drain fluids and gases from the ileum. These ICD-10-PCS codes are used for inpatient documentation when a clinician performs drainage of the ileum to evacuate fluid collections, decompress the bowel, or treat localized infection or abscess. Accurate coding within the ICD-10-PCS 0D9B group is essential for proper inpatient reimbursement, as it captures the procedure performed and the specific anatomic site, supporting appropriate case mix assignment and payment.

Ileum Drainage Procedure Overview

Procedures in this group involve drainage of fluids or gases from the ileum and target the gastrointestinal system. These inpatient drainage procedures remove accumulated fluids or gases from the small intestine to relieve symptoms, treat infection, or manage obstruction. Accurate coding matters for inpatient reimbursement because it captures the specific anatomic site and drainage action, which affects case mix and payment.

When to Use

Use a code from this group when an inpatient procedure specifically drains fluid or gas from the ileum, such as percutaneous or open drainage of an abscess or decompression. Do not use these codes for drainage procedures involving other segments of the small intestine or for non-drainage operations.

Typical Clinical Scenarios

An elderly patient presents to the emergency department with severe abdominal pain, distention, and fever. CT shows an infected fluid collection/abscess localized to the distal ileum with surrounding inflammation; interventional radiology performs percutaneous drainage placement to evacuate purulent material and decompress the segment. A percutaneous drainage device is left in place for ongoing drainage and culture-directed therapy. Typical codes: 0D9B30Z
A middle-aged patient with Crohn disease is admitted electively for worsening obstructive symptoms and a contained ileal phlegmon identified on imaging. During a scheduled minimally invasive procedure, the surgeon performs a percutaneous endoscopic drainage to evacuate the phlegmon and decompress the involved ileal segment to control inflammation prior to definitive bowel resection. A drainage catheter is placed endoscopically for continued decompression. Typical codes: 0D9B40Z
A postoperative patient who previously had ileal surgery develops a persistent enteric fistula with a localized fluid collection at the ileum not resolving with conservative care. The team performs open surgical drainage and places a drain to control ongoing contamination and allow the fistula to mature before further reconstructive procedures. Open drainage with a drain device is used because of adhesions and need for direct visualization. Typical codes: 0D9B00Z
