Veins (B5) ICD-10-PCS
The B5 body system covers Imaging procedures on veins, with 1,026 ICD-10-PCS codes across 5 root operations, 1,016 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 B5 Body System
In ICD-10-PCS, the root operation B5 - Veins within the Imaging section refers to the diagnostic visualization of veins using various imaging techniques. This operation focuses on capturing detailed images of the venous structures to aid in diagnosis and treatment planning.
The B5 - Veins imaging codes include several modalities, each highlighting different technological approaches. For instance, Plain Radiography (B50) produces planar images by capturing external ionizing radiation on photographic plates. Fluoroscopy (B51) provides real-time, single or bi-plane visualization using fluorescent screens, with digital or analog storage options. More advanced imaging techniques feature Computerized Tomography (CT Scan) (B52), which offers multiplanar digital images through multiple ionizing radiation exposures, and Magnetic Resonance Imaging (MRI) (B53), which uses radio frequency signals in a magnetic field to create detailed multiplanar images. Lastly, Ultrasonography (B54) leverages high frequency sound waves to produce real-time anatomic and flow images of veins. Understanding these vein imaging codes is essential for accurate procedural documentation and clinical decision-making.
Questions About This Page
How many codes are in the B5 body system?
The B5 body system contains 1,026 ICD-10-PCS codes in FY 2026, organized into 5 root operations. 1,016 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.
