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 BD49 includes procedures performed to image gastrointestinal structures in the duodenum. These ICD-10-PCS codes are used for inpatient documentation when real-time ultrasonographic evaluation of the duodenum is performed to assess anatomy or detect pathology. Accurate coding within the ICD-10-PCS BD49 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Duodenum Ultrasonography Procedure Overview

Procedures in this group involve real-time ultrasonographic imaging of the duodenum, capturing reflected high-frequency sound waves to create images of the gastrointestinal mucosa and wall. These procedures target the gastrointestinal system and are used to evaluate duodenal anatomy and pathology such as masses, wall thickening, or obstruction. Accurate ICD-10-PCS coding ensures inpatient records reflect the imaging performed and supports appropriate case mix assignment for reimbursement.

When to Use

Use a code from this group when a clinician performs real-time ultrasonographic imaging of the duodenum during an inpatient encounter to evaluate suspected duodenal disease or monitor an existing condition. Codes in this group are selected when the primary operation is ultrasonography of the duodenum and should be documented in the operative or procedure report.

ICD-10-PCS Code	Description
BD49ZZZ	Ultrasonography of Duodenum

Typical Clinical Scenarios

An elderly patient is admitted with acute upper abdominal pain, persistent vomiting, and signs of small-bowel obstruction on plain films; clinicians suspect obstructing lesion or severe inflammatory stricture in the proximal small bowel and request inpatient imaging to evaluate duodenal patency and wall thickness in real time. A bedside ultrasonography focused on the duodenum is performed to assess for mass effect, edema, or obstruction before further intervention. Typical codes: BD49ZZZ
A hospitalized patient with known duodenal ulcer disease and chronic anemia undergoes planned inpatient evaluation after recent melena and hemodynamic stabilization; the team needs targeted imaging to assess ulcer-related wall abnormalities, mural blood flow, or complications in the duodenum as part of the diagnostic workup. Real-time duodenal ultrasonography is used to visualize mucosal and wall changes and to guide further endoscopic or surgical planning. Typical codes: BD49ZZZ
A postoperative patient develops fever and localized upper abdominal tenderness after pancreaticoduodenectomy, raising concern for duodenal stump leak or localized fluid collection affecting the duodenal segment; clinicians obtain focused ultrasonographic imaging of the duodenum to evaluate for anastomotic disruption, adjacent collections, or altered duodenal anatomy contributing to the complication. Real-time ultrasonography of the duodenum aids rapid bedside assessment in the inpatient setting. Typical codes: BD49ZZZ
