How many codes are in the XK body system?
The XK body system contains 3 ICD-10-PCS codes in FY 2027, organized into 1 root operations. 2 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.
