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
Foot Vein, Right
The right foot venous network consists of the dorsal venous arch and associated superficial and deep veins draining the toes and forefoot, vessels that are small in caliber and lie close to the skin surface, tendons, and cutaneous nerves. Excision of a foot vein segment is typically performed for a localized varicosity, a venous malformation, or a thrombosed or symptomatic superficial vein causing pain or cosmetic concern, procedures usually done under local or regional anesthesia given the vessels' superficial course. Because these veins have abundant collateral connections and drain into the larger saphenous and deep systems proximally, documentation should note the specific vein involved (dorsal, plantar, or digital) and confirm removal was limited to the diseased segment.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
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.
