Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision procedures on the upper arteries involve cutting out a portion of an artery in the chest, neck, shoulder, or arm without replacing the tissue removed. Surgeons perform this when a segment of vessel wall has been damaged by trauma, contains a diseased or aneurysmal section, or holds a tumor or growth that needs to be removed for diagnosis or treatment. Common targets include the subclavian, axillary, brachial, and carotid arteries, along with the thoracic aorta and its major branches supplying the upper body.
The removed tissue is often small relative to the vessel and does not always require reconstruction of the artery afterward, distinguishing it from more extensive resections. Patients undergo this procedure to address localized disease, obtain a biopsy sample, or clear away scarred or narrowed sections that are interfering with blood flow to the arms, neck, or brain.
Anatomy & Axis Detail
Brachial Artery, Right
The right brachial artery is the direct continuation of the axillary artery running down the medial aspect of the upper arm, a vessel familiar to clinicians as the standard site for blood pressure auscultation and a common access point for catheter-based procedures. Excision of a segment is typically indicated for aneurysm, often related to repeated catheterization or dialysis access complications, for traumatic injury, or for a mass adjacent to the vessel wall. Its relatively superficial course alongside the median nerve makes it more accessible than the more proximal upper extremity arteries, but nerve proximity still requires careful dissection, and the operative note should specify whether the excised segment was replaced with graft material or simply removed.
Approach: Percutaneous
Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.
Coding & Documentation
Coders assign an Excision code when the operative note documents that only a portion of the artery wall or a discrete lesion was cut out, with no device left behind to replace the excised tissue. Supporting documentation should specify the exact artery involved down to the branch level available in the code tables, since upper artery anatomy is finely subdivided between innominate, subclavian, axillary, brachial, and their many named branches.
The most frequent assignment error is confusing Excision with Resection when an entire arterial segment or branch is removed rather than just a portion, or with Extirpation when the material taken out is a clot, foreign body, or other abnormal solid matter rather than vessel tissue itself. Coders also need to check whether the excision was performed as a biopsy, which changes the qualifier used, and whether an autograft was harvested from the artery for use elsewhere, which is coded separately from a diagnostic or therapeutic excision.
