ICD-10-PCS Code For Hepatobiliary System: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BF4C includes procedures performed to image anatomy and flow information in the hepatobiliary system and pancreas using ultrasonography. These ICD-10-PCS codes are used for inpatient documentation when real-time diagnostic or procedural ultrasound of the hepatobiliary system and pancreas is performed. Accurate coding within the ICD-10-PCS BF4C group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Hepatobiliary System Ultrasonography Procedure Overview

This procedure group includes real-time ultrasonography examinations that capture reflected high-frequency sound waves to produce images of the hepatobiliary system and pancreas. Procedures in this group target the hepatobiliary system and pancreas to visualize anatomy and flow information for diagnosis and guidance. Accurate ICD-10-PCS coding is important for inpatient reimbursement because it documents the imaging performed and supports correct case mix and payment.

ICD-10-PCS Code	Description
BF4CZZZ	Ultrasonography of Hepatobiliary System, All

Typical Clinical Scenarios

A patient presents to the emergency department with sudden-onset right upper quadrant pain, fever, and jaundice suspicious for acute cholangitis or obstructing choledocholithiasis; the patient is admitted for IV antibiotics and possible biliary intervention, and an inpatient real-time hepatobiliary ultrasound is performed to evaluate the biliary tree, gallbladder, and liver for stones, dilation, or pus prior to endoscopic or surgical management. Typical codes: BF4CZZZ
An older patient with known cirrhosis and newly identified hepatic lesions on outpatient imaging is admitted for expedited diagnostic workup and staging; bedside real-time ultrasonography of the entire hepatobiliary system is performed to characterize lesion size, vascular flow, and relation to biliary structures and to guide potential biopsy planning. Typical codes: BF4CZZZ
A postoperative patient on the surgical ward develops increasing abdominal pain and leukocytosis after recent cholecystectomy, raising concern for bile leak or retained stones; inpatient hepatobiliary ultrasonography is obtained to assess for bilomas, fluid collections, or biliary obstruction as part of the complication evaluation. Typical codes: BF4CZZZ
