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 Inguinal

Right inguinal lymph nodes sit in the groin crease and drain the lower abdominal wall, external genitalia, perineum, and portions of the leg, making them a frequent site of both reactive and malignant enlargement. Excision commonly addresses metastatic spread from penile, vulvar, or anal cancer, or serves as a sentinel or excisional biopsy for melanoma of the lower body. The femoral vessels and saphenous vein run immediately deep to this nodal group, so dissection carries a recognized risk of vascular injury, seroma, and lymphedema of the leg. Because inguinal lymphadenectomy can range from a single sentinel node to a full superficial and deep dissection, the operative note should clearly state the scope of tissue removed to support accurate code assignment.

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.

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.

Commonly Confused With

ResectionExcision is closely related to Resection, separated only by whether all or just part of the body part was taken out.
DrainageIt is also confused with Drainage when the specimen obtained is fluid rather than solid tissue, and with Extraction when tissue is pulled or stripped out rather than cut with a sharp instrument.
