About the 0X Body System
The ICD-10-PCS root operations for the Upper Extremities (section Medical and Surgical, character 0X) cover a range of procedures involving modification, removal, repair, and replacement of anatomical regions of the arm and hand. These codes precisely describe interventions targeting specific body parts in this region.
For example, Alteration (code 0X0) refers to modifying the anatomic structure without impacting function, while Detachment (0X6) is the cutting off of all or part of the upper extremity. Procedures like Insertion (0XH) involve placing devices that assist physiological function without replacing the body part, whereas Replacement (0XR) and Transplantation (0XY) deal with putting in synthetic or living tissue to substitute portions of the limb. Other operations include Inspection (0XJ) for exploring the anatomy, Repair (0XQ) for restoring structure and function, and Drainage (0X9) for releasing fluids or gases. These detailed codes allow accurate documentation of upper extremity procedures in ICD-10-PCS.
Questions About This Page
How many codes are in the 0X body system?
The 0X body system contains 2,336 ICD-10-PCS codes in FY 2026, organized into 16 root operations. 2,304 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.
