Cutting out or off, without replacement, all of a body part
Procedure Overview
Resection covers the complete removal of an entire lymphatic or hemic body part, without replacing it, and is one of the more consequential procedure types in this family because it permanently eliminates that structure. The most familiar example is total splenectomy, removing the entire spleen after severe trauma, certain blood disorders, or an enlarged spleen that is failing or at risk of rupture. Other examples include complete thymectomy for thymic tumors or myasthenia gravis, and full lymphadenectomy, where an entire chain or region of lymph nodes is removed, often as part of cancer staging or treatment to prevent disease spread.
Because these organs and nodes support immune defense and fluid balance, patients undergoing resection are usually counseled about the tradeoffs, such as increased infection risk after splenectomy, before the procedure is performed.
Anatomy & Axis Detail
Lymphatic, Left Lower Extremity
This code describes complete removal of lymphatic vessels and nodes draining the left leg, ankle, and foot, structures that channel lymph upward through the popliteal and femoral chains toward the left inguinal nodes. Surgeons resect this tissue when imaging or biopsy has already identified disease confined to these nodes, such as a primary lymphatic malignancy or a metastatic deposit requiring full clearance rather than partial sampling. Because the lower extremity depends on this chain for fluid return, taking out the full network raises meaningful concern for postoperative lymphedema, and surgeons often coordinate with reconstructive teams when extensive clearance is planned. Coders should confirm the operative note describes cutting out all of the diseased lymphatic tissue in this territory, using laterality to distinguish this code from its right-sided counterpart and from adjacent inguinal or extremity-only resections.
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
Documentation must clearly state that the entire body part was removed, not a portion of it, since removing only part of an organ or only some nodes in a chain is coded as Excision rather than Resection. This distinction is one of the most frequent sources of coding errors in this family, especially with lymphadenectomies, where a note describing removal of "regional lymph nodes" needs to specify whether the entire nodal chain or basin was taken versus a sampling of nodes. Coders also need to confirm the specific body part value that matches the region resected, such as spleen versus a named lymph node group, and should check whether any adjacent structures were resected in the same operation, which would require additional codes.
