| Chars 1–3 | Root Operation | Codes | Billable |
|---|---|---|---|
| BD1 | 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 | 34 | 32 |
| BD2 | Computerized Tomography (CT Scan)Computer-reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation | 16 | 14 |
| BD4 | UltrasonographyReal time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves | 14 | 12 |

About the BD Body System
In ICD-10-PCS, the root operation BD for the Gastrointestinal System refers to various Imaging techniques used to visualize internal structures for diagnostic purposes. This operation involves creating images without physically changing the body.
The Gastrointestinal System Imaging includes methods like Fluoroscopy (code BD1), which provides real-time X-ray images using a fluorescent screen, often stored digitally. Another example is Computerized Tomography (CT Scan) (code BD2), which offers detailed, cross-sectional digital images by combining multiple ionizing radiation exposures. Additionally, Ultrasonography (code BD4) uses high-frequency sound waves to produce live images of anatomy or blood flow without radiation exposure. These codes enable precise documentation of noninvasive imaging procedures within the gastrointestinal tract, supporting accurate diagnosis and treatment planning.
Questions About This Page
How many codes are in the BD body system?
The BD body system contains 64 ICD-10-PCS codes in FY 2026, organized into 3 root operations. 58 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.
