Non-Axial Upper Bones (BP) ICD-10-PCS
The BP body system covers Imaging procedures on non-axial upper bones, with 280 ICD-10-PCS codes across 5 root operations, 275 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.
Root Operations in This Body System 5 operations · 280 codes
| 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 | 53 | 52 |
| BP1 | 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 | 49 | 48 |
| BP2 | Computerized Tomography (CT Scan)Computer-reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation | 124 | 123 |
| 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 | 37 | 36 |
| BP4 | UltrasonographyReal time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves | 17 | 16 |

About the BP Body System
These imaging codes show sites including the shoulders, arms, hands, their joints, ribs and thorax. The body-part character identifies the site; its values distinguish right, left and some bilateral sites.
Plain radiography makes flat images using external radiation. Fluoroscopy shows radiation images in real time. CT uses multiple radiation exposures to produce images across several planes. MRI uses signals in a magnetic field, while ultrasonography uses reflected sound waves to show images in real time.
Questions About This Page
How many codes are in the BP body system?
The BP body system contains 280 ICD-10-PCS codes in FY 2027, organized into 5 root operations. 275 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.
