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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BD42 includes procedures performed to image the stomach using ultrasonography in the gastrointestinal system. These ICD-10-PCS codes are used for inpatient documentation when real-time diagnostic ultrasonography of the stomach is performed to assess anatomy or flow information. Accurate coding within the ICD-10-PCS BD42 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Stomach Ultrasonography Procedure Overview

This procedure group includes real-time ultrasonography of the stomach, using reflected high-frequency sound waves to create images of the gastrointestinal system. Procedures in this group target the stomach and surrounding structures to evaluate anatomy and flow information relevant to diagnosis and treatment. Accurate ICD-10-PCS coding for these imaging procedures is important for capturing the inpatient service provided and supporting appropriate reimbursement.

ICD-10-PCS Code	Description
BD42ZZZ	Ultrasonography of Stomach

Typical Clinical Scenarios

An elderly patient is admitted with acute upper abdominal pain, persistent vomiting, and concern for gastric outlet obstruction after recent weight loss and dehydration; inpatient evaluation includes bedside real-time ultrasonography to assess stomach distension, wall thickening, and gastric emptying to guide urgent management and possible endoscopic intervention. Typical codes: BD42ZZZ
A hospitalized patient with known gastric malignancy undergoes planned inpatient imaging to monitor tumor progression and evaluate changes in gastric wall morphology and local fluid collections; real-time ultrasonography of the stomach is used to document anatomy and guide multidisciplinary treatment planning during the admission. Typical codes: BD42ZZZ
A postoperative patient develops new-onset epigastric pain and suspected localized fluid collection near the stomach after abdominal surgery; inpatient diagnostic ultrasonography is performed at the bedside to evaluate for gastric leak, perigastric fluid, or other complications affecting the stomach that require prompt clinical decision-making. Typical codes: BD42ZZZ
