Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision procedures remove a portion of a lymph node, the spleen, the thymus, or another lymphatic or hemic structure, without replacing it, most commonly to obtain a tissue sample for diagnosis. Lymph node biopsies fall squarely in this family and are frequently used to stage cancers such as lymphoma or breast cancer, or to investigate unexplained swelling.
Because these excisions are usually diagnostic, the tissue removed is sent to pathology for microscopic examination, and the results often guide decisions about further treatment such as chemotherapy or additional surgery. A partial splenectomy performed to preserve some immune function while removing damaged tissue is another example within this family.
These procedures range from a quick outpatient biopsy under local anesthesia to a more involved surgical excision requiring general anesthesia, depending on the location and size of the tissue being sampled.
Anatomy & Axis Detail
Lymphatic, Right Upper Extremity
Lymph nodes of the right upper extremity, including the epitrochlear node near the medial elbow and scattered nodes along the brachial and basilic vessels, drain the hand, forearm, and arm and are excised chiefly to evaluate reactive or metastatic adenopathy from an infection, melanoma, or squamous cell carcinoma originating distally in the limb. Because these nodes are superficial and relatively isolated from major neurovascular bundles compared with axillary or neck nodes, excisional biopsy here is usually a lower-risk outpatient procedure, though care is still taken around the basilic vein and medial antebrachial cutaneous nerve near the elbow. This excision targets a node outside the axilla, which is relevant when staging melanoma with in-transit or epitrochlear nodal involvement before or in addition to axillary dissection. The specific limb segment and node location should be documented to clarify the drainage basin being sampled.
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
A code from this family requires documentation that a portion of the lymphatic or hemic structure was physically cut out and removed from the body, with the rest of the structure left in place. The body part value must match the specific node group or organ documented, such as an axillary versus inguinal lymph node.
A persistent source of error is distinguishing an excisional lymph node biopsy from a full lymph node dissection, where an entire chain or region of nodes is removed; the latter is typically coded as Resection rather than Excision. Coders should also check whether the entire structure, such as the whole spleen, was removed, which again points to Resection instead.
