Urinary System (0T) ICD-10-PCS
The 0T body system covers Medical and Surgical procedures on urinary system, with 4,030 ICD-10-PCS codes across 24 root operations, 3,982 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.

About the 0T Body System
The ICD-10-PCS classification for the Urinary System includes a broad range of root operations that describe various procedures performed on urinary tract structures. These root operations define distinct clinical actions such as altering, removing, or examining urinary body parts.
Examples in this section demonstrate the diversity of interventions: Bypass (code starting with 0T1) alters the route of passage through tubular urinary structures, while Dilation (0T7) involves expanding an orifice or lumen. Procedures like Excision (0TB) and Resection (0TT) describe cutting out portions or whole urinary body parts without replacement. Removal or manipulation of devices is coded under Change (0T2) and Removal (0TP). More complex interventions include Replacement (0TR), which inserts biological or synthetic materials to substitute part of a urinary structure, and Transplantation (0TY), placing living tissue from another individual. Understanding these codes ensures precise documentation of surgical and diagnostic procedures within the urinary system.
Questions About This Page
How many codes are in the 0T body system?
The 0T body system contains 4,030 ICD-10-PCS codes in FY 2026, organized into 24 root operations. 3,982 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.
