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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BD48 includes procedures performed to image anatomical structures in the appendix. These ICD-10-PCS codes are used for inpatient documentation when real-time ultrasonography of the appendix is performed to evaluate anatomy or flow information. Accurate coding within the ICD-10-PCS BD48 group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Appendix Ultrasonography Procedure Overview

This procedure group includes real-time display ultrasonography of the appendix, a component of the gastrointestinal system used to generate images from reflected high-frequency sound waves. Procedures in this group involve capturing and displaying dynamic images of appendiceal anatomy or flow information to aid diagnosis or guide care. Accurate ICD-10-PCS coding for these procedures ensures inpatient records reflect the imaging performed and supports appropriate reimbursement.

ICD-10-PCS Code	Description
BD48ZZZ	Ultrasonography of Appendix

Typical Clinical Scenarios

A young adult presents to the emergency department with acute right lower quadrant abdominal pain, fever, and leukocytosis suspicious for acute appendicitis; the patient is admitted for observation and workup, and real-time ultrasonography of the appendix is performed to evaluate appendiceal inflammation and guide the decision for urgent surgical intervention. Typical codes: BD48ZZZ
An older patient with chronic intermittent abdominal discomfort and a history of nonspecific gastrointestinal imaging is admitted for planned diagnostic evaluation when outpatient studies were inconclusive; inpatient real-time ultrasonography of the appendix is performed to assess anatomy and rule out chronic appendiceal pathology as part of a nonemergent diagnostic workup. Typical codes: BD48ZZZ
A postoperative patient develops localized right lower quadrant tenderness and low-grade fever after recent abdominal surgery, raising concern for an appendiceal complication or abscess; bedside real-time ultrasonography of the appendix is performed in the inpatient setting to evaluate for acute appendiceal abnormality or fluid collection that may alter management. Typical codes: BD48ZZZ
