About the 05 Body System
These codes cover procedures on veins such as the azygos, jugular, subclavian, axillary, hand, face and intracranial veins. The body-part character identifies the vein and, where listed, its right or left side.
The tables include bypass to change the route through a vein, dilation to widen it, and restriction or occlusion to partly or fully close it. Others drain fluid or gas, remove or break up solid matter, or cut out, pull away, or destroy part of a vein. They also cover inspecting, freeing, moving, repairing, replacing or reinforcing a vein. Device procedures put in a nonbiological appliance, remove a device, or correct a malfunctioning or displaced device.
Questions About This Page
How many codes are in the 05 body system?
The 05 body system contains 2,505 ICD-10-PCS codes in FY 2027, organized into 19 root operations. 2,486 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.
