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, Aortic
Aortic lymph nodes, also called para-aortic or lumbar nodes, sit along the abdominal aorta and receive drainage from the testes, ovaries, kidneys, and posterior abdominal wall. Excision of this group is a key step in staging testicular and ovarian cancers, since these organs bypass pelvic nodes and drain directly to the aortic chain via the gonadal vessels. The nodes lie in close proximity to the renal vessels, inferior vena cava, and lumbar sympathetic trunk, making the dissection technically demanding and prone to bleeding or nerve injury if not performed with meticulous exposure. Retroperitoneal lymph node dissection for testicular cancer is a common clinical scenario generating this code, and the operative note should clarify the extent of nodal tissue removed relative to the great vessels.
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.
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.
