About the DT Body System
The ICD-10-PCS root operation DT refers to Radiation Therapy applied to the Urinary System. This operation encompasses delivering targeted radiation to treat urinary system conditions, typically cancers, using different therapeutic techniques.
Radiation Therapy for the urinary system can be administered via several methods. Beam Radiation (DT0) involves externally aiming high-energy rays at tumors using a machine. Alternatively, Brachytherapy (DT1) places radioactive material directly into or near the tumor through seeds, needles, wires, or catheters. Another precise technique is Stereotactic Radiosurgery (DT2), which uses specialized equipment to deliver a single, high-dose radiation session focused accurately on the tumor. Finally, the DTY code covers other radiation types not specifically categorized. These detailed radiation therapy codes are essential for accurately documenting the specific approach used in managing urinary system malignancies.
Questions About This Page
How many codes are in the DT body system?
The DT body system contains 240 ICD-10-PCS codes in FY 2026, organized into 4 root operations. 232 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.
