Veins (B5) ICD-10-PCS
The B5 body system covers Imaging procedures on veins, with 513 ICD-10-PCS codes across 5 root operations, 508 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 |
|---|---|---|---|
| B50 | Plain RadiographyPlanar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate | 85 | 84 |
| B51 | 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 | 225 | 224 |
| B52 | Computerized Tomography (CT Scan)Computer-reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation | 105 | 104 |
| B53 | 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 | 49 | 48 |
| B54 | UltrasonographyReal time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves | 49 | 48 |

About the B5 Body System
These codes describe imaging of veins, including cerebral and cerebellar veins, veins in the limbs, and a dialysis shunt or fistula.
The tables distinguish still X-ray images, live X-ray images, CT images built from multiple X-ray exposures, MRI images made using a magnetic field, and sound-wave images. The body part value identifies the vein or other imaged site and distinguishes right, left, or both sides where those choices appear.
The Index also directs venography, phlebography, and guidance for catheter placement to these tables.
Questions About This Page
How many codes are in the B5 body system?
The B5 body system contains 513 ICD-10-PCS codes in FY 2027, organized into 5 root operations. 508 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.
