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, Left Upper Extremity

On the left upper extremity, nodes such as the epitrochlear node above the medial epicondyle and scattered lymphatics along the brachial vessels collect drainage from the hand, forearm, and arm, and excision is typically prompted by a palpable mass, chronic infection, or the need to stage melanoma or another skin cancer arising on that limb. The relative absence of major nerves directly overlying these superficial nodes makes excision technically straightforward compared with deeper nodal basins, though the ulnar nerve's proximity at the elbow warrants care when working near the epitrochlear node. Because in-transit lymphatic spread can occur before disease reaches the axilla, sampling a left arm node separately from the axillary chain provides additional staging information for extremity melanoma. Laterality and precise anatomic location within the limb should be recorded to distinguish this from an axillary procedure.

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.

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.
