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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0DB9 includes procedures performed to excise portions of the duodenum in the gastrointestinal system. These ICD-10-PCS codes are used for inpatient documentation when a segment of the duodenum is surgically removed without replacement to treat disease, injury, or obstruction. Accurate coding within the ICD-10-PCS 0DB9 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

When to Use

Use a code from this group when a surgeon removes part of the duodenum during an inpatient procedure and no replacement or reconstruction of the removed segment is performed. These codes apply when the primary operative intent is excision for reasons such as malignancy, ischemia, perforation, or other pathologic conditions.

Typical Clinical Scenarios

An older adult presents emergently with severe abdominal pain, hemodynamic instability, and radiographic evidence of a perforated duodenal ulcer with free intraperitoneal air. The patient is taken to the operating room for open surgical exploration and removal of the necrotic/ perforated segment of duodenum without reconstruction to control contamination and source of sepsis. Typical codes: 0DB90ZZ.
A middle-aged patient with a biopsy-proven duodenal adenocarcinoma is admitted electively for segmental resection of the tumor after preoperative staging; the surgeon removes the involved portion of the duodenum without immediate replacement as part of a planned oncologic excision. Typical codes: 0DB94ZZ, 0DB97ZZ.
A patient who previously underwent endoscopic management for severe duodenal ischemia returns with ongoing obstruction and recurrent localized necrosis; after failed conservative therapy, a percutaneous excision of the nonviable duodenal segment is performed during inpatient admission to alleviate obstruction and remove devitalized tissue. Typical codes: 0DB93ZZ, 0DB93ZX.
