About the 0X Body System
These codes cover procedures on upper-extremity regions, from the shoulder and armpit to the arm, wrist, hand and fingers. The body-part character identifies the site and distinguishes right from left.
Some procedures change a part’s shape without changing its function, inspect it, or stop acute bleeding. Others drain fluid or gas, cut away part of a body part, or cut off part of an extremity. Device procedures insert, remove, exchange, or correct a device or its position. Other procedures repair a body part, reattach a separated part, or move a part to take over another part’s function. Material may replace or reinforce a body part; transplantation uses a living part from another individual or animal.
Questions About This Page
How many codes are in the 0X body system?
The 0X body system contains 1,168 ICD-10-PCS codes in FY 2027, organized into 16 root operations. 1,152 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.
