Non-Axial Upper Bones (BP) ICD-10-PCS
The BP body system covers Imaging procedures on non-axial upper bones, with 560 ICD-10-PCS codes across 5 root operations, 550 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.

| Chars 1–3 | Root Operation | Codes | Billable |
|---|---|---|---|
| BP0 | Plain RadiographyPlanar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate | 106 | 104 |

| BP3 | 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 | 74 | 72 |
| BP4 | UltrasonographyReal time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves | 34 | 32 |

About the BP Body System
The ICD-10-PCS root operation Non-Axial Upper Bones in the Imaging classification refers to various diagnostic imaging techniques used to visualize the upper bones from non-axial perspectives. This operation supports detailed examination without performing invasive procedures.
Several specific imaging modalities illustrate this root operation, including Plain Radiography (BP0), which uses external ionizing radiation captured on photographic plates to produce planar images. Fluoroscopy (BP1) provides real-time single or bi-plane imaging displayed on fluorescent screens, which can also be digitally stored. Advanced techniques like Computerized Tomography (CT Scan) (BP2) create computer-reformatted multiplanar images from multiple radiation exposures. Magnetic Resonance Imaging (MRI) (BP3) captures radiofrequency signals within a magnetic field to generate detailed multiplanar images, while Ultrasonography (BP4) uses high-frequency sound waves to visualize anatomy and flow in real time. These diverse codes emphasize the breadth of diagnostic tools available for studying upper bones non-invasively.
Questions About This Page
How many codes are in the BP body system?
The BP body system contains 560 ICD-10-PCS codes in FY 2026, organized into 5 root operations. 550 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.
