Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
This family covers surgical removal of a portion of a vein in the leg, groin, pelvis, or lower abdomen, without replacing the tissue taken out. In the lower extremities this most often means cutting away a segment of a varicose or diseased superficial vein, such as a stab avulsion of tributary branches during varicose vein surgery, or taking a wedge or segment of a deeper vein like the femoral or popliteal for diagnostic biopsy. The vein tissue removed is typically sent to pathology or discarded because it is no longer functioning normally.
Surgeons perform these procedures to relieve symptoms from varicose disease (aching, swelling, skin changes), to diagnose suspected vascular tumors or inflammatory conditions of the vein wall, or to remove a vein segment that will be reused elsewhere in the body, such as harvesting the greater saphenous vein for coronary or peripheral bypass grafting. Unlike stripping the entire length of a vein, excision here refers to taking out a defined portion while leaving the rest of the vein bed intact.
Patients typically undergo this under local, regional, or general anesthesia depending on how extensive the removal is, and recovery is usually brief for isolated segment excisions such as saphenous vein harvest or stab avulsions.
Anatomy & Axis Detail
Lower Vein
This entry applies when a lower extremity or pelvic vein excision does not correspond to one of the specifically named vessels, such as an unlisted tributary, an accessory or duplicated venous channel, or a small perforator vein connecting the superficial and deep systems. Excision in these cases removes a segment of an abnormal or diseased vein, often identified incidentally during another vascular or pelvic procedure, for reasons such as a localized varicosity, a venous malformation, or scarring from prior injury or thrombosis. Because the specific vessel does not map to a designated body part value, documentation should describe its anatomic location and course in enough detail to justify use of this general classification rather than a more precise one.
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: Hemorrhoidal Plexus
This qualifier refers to the hemorrhoidal venous plexus surrounding the anorectal canal, used when a procedure targets this network directly, such as sclerotherapy or ligation performed for symptomatic hemorrhoids. It differs from Rectum, which denotes the bowel wall itself rather than the venous cushions embedded within it.
Coding & Documentation
A coder should confirm the operative note describes cutting out a discrete portion of vein, not stripping the entire vessel with a stripper device and not simply ligating or tying it off. Documentation should specify the named vein (great saphenous, small saphenous, femoral, popliteal, or an unspecified lower extremity vein) and confirm no graft or substitute material replaced the excised segment. Saphenous vein harvest for later use as a bypass conduit still codes to Excision in this body system even though the vein is destined for use elsewhere, because nothing replaces it at the harvest site.
The most common assignment error is confusing Excision with Extraction when the operative report actually describes stripping the full length of the saphenous vein with a stripper wire or endovenous device, which is Extraction because force is used to pull the vessel out rather than cut it in sections. Coders also sometimes default to Excision for stab avulsion phlebectomy of varicose tributaries when the documentation actually supports a different root operation if the vein is being obliterated in place rather than physically removed.
