About the DU Body System
The ICD-10-PCS root operation DU represents Radiation Therapy applied to the Female Reproductive System. This operation involves using targeted radiation to treat diseases, primarily cancer, in specified reproductive organs.
Radiation Therapy for the female reproductive system includes several methods documented by specific codes. Beam Radiation (DU0) directs high-energy rays at cancer from outside the body. Brachytherapy (DU1) involves placing radioactive material such as seeds or catheters directly into or near a tumor for internal radiation. Another approach, Stereotactic Radiosurgery (DU2), uses advanced equipment to deliver a precise, high radiation dose in a single session. The category also allows for Other Radiation types (DUY) when they don’t fit standard classifications. These codes ensure accurate reporting of radiation treatments specific to the female reproductive organs, aiding in clinical documentation and treatment planning.

How many codes are in the DU body system?
The DU body system contains 182 ICD-10-PCS codes in FY 2026, organized into 4 root operations. 174 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.
