About the XR Body System
These New Technology codes cover joints in the spine, sacroiliac joints, knees, ankles, and tarsal joints of the foot. The body-part character identifies the joint, distinguishes right from left where listed, and separates single from multiple spinal joints.
Fusion joins parts of a joint so it cannot move. Insertion places an appliance that monitors, aids, carries out, or prevents a body function without replacing a body part. Replacement places material in or on a joint to take the place of all or part of it.
FY 2027 changes: The FY 2027 ICD-10-PCS update, effective October 1, 2026, added 12 codes and deleted 12 codes in this body system. Tables with changes: XRG Fusion and XRH Insertion.
Questions About This Page
How many codes are in the XR body system?
The XR body system contains 83 ICD-10-PCS codes in FY 2027, organized into 3 root operations. 80 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.
