About the 06 Body System
The ICD-10-PCS Lower Veins category in the Medical and Surgical section covers various root operations performed on veins in the lower extremities. These procedures involve modifying, removing, or examining parts of the venous system to treat or diagnose conditions.
Each root operation defines a specific action: for example, Bypass (061) reroutes blood flow around a blocked vein, while Destruction (065) physically eradicates diseased venous tissue using energy or force. Other key operations include Dilation (067) to expand the vein’s lumen, Drainage (069) to remove fluids or gases, and Excision (06B) which involves cutting out a portion of the vein. Healthcare professionals may also perform Inspection (06J) to visually or manually explore veins or Occlusion (06L) to completely close off a vein. Additional procedures like Repair (06Q) restore venous structure and function, and Replacement (06R) involves installing materials that substitute for vein segments. Understanding these lower vein procedure codes aids accurate documentation and clinical communication regarding vascular interventions.
Questions About This Page
How many codes are in the 06 body system?
The 06 body system contains 4,732 ICD-10-PCS codes in FY 2026, organized into 19 root operations. 4,694 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.
