About the 06 Body System
These codes cover procedures on veins such as the portal, splenic, renal, iliac, femoral, and foot veins. The body-part character names the vein and distinguishes right from left where those values appear.
The tables include rerouting what passes through a vein, widening its opening, and closing that opening partly or completely. Other procedures remove, strip out, or destroy vein tissue; drain fluid or gas; or remove or break up solid matter. The tables also cover inspecting, freeing, moving, repairing, replacing, or reinforcing a vein, as well as putting in or working on a device.
Questions About This Page
How many codes are in the 06 body system?
The 06 body system contains 2,366 ICD-10-PCS codes in FY 2027, organized into 19 root operations. 2,347 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.
