ICD-10-PCS Code For Liver And Spleen: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BF46 includes procedures performed to image structures in the liver and spleen using real-time ultrasonography. These ICD-10-PCS codes are used for inpatient documentation when ultrasound imaging of the hepatobiliary system and spleen is performed to assess anatomy, pathology, or blood flow. Accurate coding within the ICD-10-PCS BF46 group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Liver And Spleen Ultrasonography Procedure Overview

This procedure group includes real-time ultrasonography of the liver and spleen, using reflected high-frequency sound waves to create images of hepatobiliary anatomy and flow information. Procedures target the Hepatobiliary System and Pancreas and involve capture and display of ultrasound images to evaluate structure and blood flow. Accurate ICD-10-PCS coding ensures inpatient records reflect the imaging performed and supports correct case mix assignment and reimbursement.

BF46ZZZ	Ultrasonography of Liver and Spleen

Typical Clinical Scenarios

A middle-aged patient is admitted with acute right upper quadrant pain, fever, and abnormal liver function tests after suspected biliary sepsis; inpatient evaluation includes bedside real-time ultrasonography to assess liver parenchyma for focal lesions, evaluate for hepatic abscess, and visualize splenic size or involvement as part of the hepatobiliary assessment. Typical codes: BF46ZZZ
An inpatient with known chronic liver disease (cirrhosis) hospitalized for evaluation of worsening abdominal distention and monitoring of disease progression undergoes scheduled real-time ultrasound imaging to document liver morphology, detect new nodules, and assess the spleen for enlargement or portal hypertension-related changes. Typical codes: BF46ZZZ
A patient following blunt abdominal trauma is admitted for observation with concern for intra-abdominal injury; real-time ultrasonography of the liver and spleen is performed in the inpatient setting to rapidly identify liver lacerations, subcapsular hematoma, or splenic injury contributing to hemodynamic instability. Typical codes: BF46ZZZ
