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 Lower Extremity
Lymphatic tissue of the right lower extremity includes the popliteal and other superficial and deep nodes distal to the inguinal region, responsible for draining the leg and foot. Excision of these nodes is typically performed to biopsy a mass, address lymphedema-related fibrotic tissue, or remove nodes involved by melanoma or soft tissue sarcoma originating in the limb. Because lower extremity lymphatics are vulnerable to disruption, surgeons must weigh the risk of postoperative lymphedema against the diagnostic or therapeutic benefit of removal, often limiting dissection to a sentinel node or a clearly defined mass. Documentation should note laterality precisely, since the coding system distinguishes right from left extremity lymphatics, and should specify whether popliteal or other named nodal groups were involved.
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 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.
