Female Reproductive System (BU) ICD-10-PCS
The BU body system covers Imaging procedures on female reproductive system, with 166 ICD-10-PCS codes across 4 root operations, 158 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 |
|---|---|---|---|
| BU0 | Plain RadiographyPlanar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate | 38 | 36 |
| BU1 | 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 | 50 | 48 |
| BU3 | 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 | 44 | 42 |
| BU4 | 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 BU Body System
The ICD-10-PCS root operation Imaging for the Female Reproductive System involves capturing diagnostic images to visualize anatomical structures without invasion. This operation is key for noninvasive evaluation and treatment planning within the female reproductive body system.
This classification includes various imaging techniques such as Plain Radiography (code BU0), which produces planar images using external ionizing radiation; and Fluoroscopy (code BU1), offering real-time X-ray imaging with the capability for image storage. Advanced modalities like Magnetic Resonance Imaging (MRI) (code BU3) provide detailed multiplanar digital images based on radio frequency signals within a magnetic field. Additionally, Ultrasonography (code BU4) delivers real-time images using high frequency sound waves to assess anatomical structures and flow. Proper coding with these female reproductive system imaging codes ensures precise documentation of the diagnostic method used in clinical practice.
Questions About This Page
How many codes are in the BU body system?
The BU body system contains 166 ICD-10-PCS codes in FY 2026, organized into 4 root operations. 158 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.
