Operation Definition

Cutting out or off, without replacement, a portion of a body part

Procedure Overview

Excision procedures in the upper veins involve cutting out a portion of a diseased or damaged vein without replacing it, most commonly to remove a segment affected by phlebitis, a varicosity, a tumor, or a section of vessel that has been injured. Because these are superficial or accessible veins in the arm, chest, or neck, excision is frequently done to relieve pain, improve appearance, or eliminate a source of clotting or infection rather than to restore blood flow, since the upper extremity has extensive collateral venous drainage.

A surgeon typically makes a small incision over the affected vein, isolates the segment, and removes it while leaving the surrounding tissue intact. Excised tissue may also be sent for biopsy when the reason for removal is to evaluate a suspicious growth or mass involving the vein wall.

Anatomy & Axis Detail

Axillary Vein, Left

The left axillary vein continues from the brachial vein at the teres major tendon and becomes the subclavian vein at the first rib, coursing through the axilla in close relation to the axillary artery and brachial plexus cords. Excision of a portion of this vein addresses localized pathology such as a venous aneurysm, a chronically scarred segment from prior catheter or port placement, or invasion by an adjacent soft tissue mass. The deep location beneath the pectoral muscles means the surgeon works near dense lymphatic tissue and axillary nodes, so care is taken to limit disruption that could lead to arm swelling afterward. Its proximity to major neurovascular structures of the upper limb also demands careful, deliberate dissection. Documentation should specify the exact segment removed and whether the vessel was ligated or repaired following excision.

Approach: Open

Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.

Qualifier: Diagnostic

Applied chiefly to Excision, this qualifier marks that tissue was removed specifically for diagnostic purposes, i.e., a biopsy intended for pathologic evaluation rather than to treat disease. It distinguishes biopsy-type excisions from therapeutic excisions of the same body part, which are coded without this qualifier even though the physical technique may be identical.

Coding & Documentation

Coders need documentation confirming that only a portion of the vein was removed, since removal of an entire named vein still falls under excision as long as it is not paired with a graft or synthetic replacement. The operative report should specify the exact vein segment taken and whether the tissue was sent to pathology, which supports the diagnostic qualifier when applicable.

A common mistake is defaulting to excision when the physician actually performed a resection that included reconstruction or bypass, which would instead be coded as a different root operation. Coders should also watch for procedures described as "stripping" a vein, which despite the informal terminology is typically coded to extraction rather than excision because force is used to pull the vessel out along its length.

Commonly Confused With

ExtractionExtraction is the closest source of confusion, since both remove venous tissue, but extraction specifically involves pulling or stripping the vein out using force along its course, while excision uses sharp dissection to cut out a defined segment.
ResectionResection, used when an entire body part is removed, does not apply here because ICD-10-PCS treats named vein segments individually rather than the whole venous system as one body part.
ExtirpationExtirpation is distinguished because it removes abnormal solid matter such as thrombus from within the vein rather than removing vein wall tissue itself.
