Hepatobiliary System and Pancreas (BF) ICD-10-PCS
The BF body system covers Imaging procedures on hepatobiliary system and pancreas, with 218 ICD-10-PCS codes across 6 root operations, 206 of them billable in fiscal year 2026. Each root operation defines a distinct procedural objective, and the info icons show the official definition with a preview of the codes inside.

About the BF Body System
The ICD-10-PCS root operation BF refers to Imaging of the Hepatobiliary System and Pancreas. This operation captures visual representations of these organs for diagnostic purposes without invasive entry.
Within this classification, various imaging modalities are used to obtain detailed views. For example, Plain Radiography (code BF0) produces planar images via external ionizing radiation exposure. Fluoroscopy (code BF1) offers real-time moving images, sometimes stored digitally. More advanced techniques include Computerized Tomography (CT Scan) (code BF2), providing multiplanar digital images through multiple X-ray exposures, and Magnetic Resonance Imaging (MRI) (code BF3), which uses magnetic fields and radiofrequency signals for detailed soft-tissue visualization. Ultrasonography (code BF4) captures real-time anatomical or flow information via high-frequency sound waves. There is also provision for Other Imaging modalities (code BF5) to visualize hepatobiliary and pancreatic structures through alternate specified techniques.
These specific hepatobiliary and pancreas imaging codes allow precise documentation of diagnostic procedures using different modalities tailored to patient needs and clinical settings.
Questions About This Page
How many codes are in the BF body system?
The BF body system contains 218 ICD-10-PCS codes in FY 2026, organized into 6 root operations. 206 of them are billable on inpatient claims.
What is a root operation?
The root operation is the third character of every ICD-10-PCS code and names the objective of the procedure. Drainage takes fluid out, Excision cuts out a portion of a body part, and Resection removes all of one. Picking the right root operation is the central skill of PCS coding, so each one above carries its official CMS definition.
