About the 0T Body System
These medical and surgical codes cover procedures on the kidney, kidney pelvis, ureter, bladder, bladder neck and urethra. Body-part values identify right, left or bilateral sites where those choices are listed.
The tables distinguish cutting out part of a body part from cutting out all of it. Other procedures pull tissue away, drain fluid or gas, or remove or break up solid matter. Some widen, narrow, close or reroute a passage; others separate, free, move, reattach or repair a body part. The tables also cover putting in material that replaces or reinforces a body part, transplanting a living body part, and putting in, changing, removing or correcting a device. Inspection explores a body part by sight or touch.
FY 2027 changes: The FY 2027 ICD-10-PCS update, effective October 1, 2026, added 4 codes in this body system. Table with changes: 0TX Transfer.
Questions About This Page
How many codes are in the 0T body system?
The 0T body system contains 2,023 ICD-10-PCS codes in FY 2027, organized into 25 root operations. 1,998 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.
