Hepatobiliary System and Pancreas (BF) ICD-10-PCS
The BF body system covers Imaging procedures on hepatobiliary system and pancreas, with 109 ICD-10-PCS codes across 6 root operations, 103 of them billable in fiscal year 2027. Each root operation defines a distinct procedural objective, and the info icons show the official definition with a preview of the codes inside.

| Chars 1–3 | Root Operation | Codes | Billable |
|---|---|---|---|
| BF0 | Plain RadiographyPlanar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate | 10 | 9 |
| BF1 | FluoroscopySingle plane or bi-plane real time display of an image developed from the capture of external ionizing radiation on fluorescent screen. The image may also be stored by either digital or analog means | 23 | 22 |
| BF2 | Computerized Tomography (CT Scan)Computer-reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation | 29 | 28 |
| BF3 | Magnetic Resonance Imaging (MRI)Computer reformatted digital display of multiplanar images developed from the capture of radio frequency signals emitted by nuclei in a body site excited within a magnetic field | 10 | 9 |
| BF4 | UltrasonographyReal time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves | 8 | 7 |
| BF5 | Other ImagingOther specified modality for visualizing a body part | 29 | 28 |

About the BF Body System
These codes describe imaging of the liver, gallbladder, bile ducts, pancreas and pancreatic ducts. Some body-part values name combinations of these structures or include the spleen.
The type character separates plain radiography, real-time fluoroscopy, CT, MRI, ultrasound and other specified imaging. Plain radiography, fluoroscopy and CT use radiation to make images; MRI uses magnetic fields and radio signals, while ultrasound uses sound waves. These codes also include fluorescence imaging. The body-part character distinguishes sites such as the gallbladder from combinations such as the gallbladder and bile ducts.
Questions About This Page
How many codes are in the BF body system?
The BF body system contains 109 ICD-10-PCS codes in FY 2027, organized into 6 root operations. 103 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.
