Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision procedures on the lower bones remove a portion of a bone in the pelvis, hip, leg, ankle, or foot without replacing what's taken out. Surgeons perform these when a piece of bone needs to come out but the rest of the bone can stay in place - trimming a bone spur pressing on a nerve, taking a wedge sample from a suspicious lesion to send for biopsy, or shaving down a prominent area that's causing pain or skin breakdown.
Because only part of the bone is involved, the surrounding structure typically remains functional. Recovery often centers on protecting the area while it heals rather than rebuilding lost function, though larger excisions near a joint may need a period of limited weight-bearing.
Anatomy & Axis Detail
Femoral Shaft, Left
The left femoral shaft is the straight, cylindrical diaphyseal segment of the thighbone lying between the hip and knee, built of thick cortical bone to withstand axial loading during standing and gait. Excision of a portion of this bone is typically undertaken to remove infected or dead cortex in osteomyelitis, sample tissue from a bone lesion, or excise a benign growth such as an osteochondroma arising from the shaft. Because removing shaft cortex can compromise the femur's load-bearing capacity, surgeons weigh the size and location of the excised segment carefully and may plan for stabilization afterward. The procedure is generally performed through a lateral surgical approach, and documentation should clarify whether the excision was limited to cortical bone or extended into the medullary cavity.
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.
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
Assign an excision code when the operative note describes cutting out a discrete portion of a lower bone - an exostosis, an osteophyte, a bone biopsy specimen, or margins around a tumor - without inserting a device or graft to replace the missing bone. The note should specify the bone and the general region (e.g., femoral neck, calcaneus) since Lower Bones is subdivided by specific bone. A common assignment error is coding excision when the surgeon actually removed the entire bone or a full bony process, which is resection; another is missing that a biopsy taken via excisional technique still codes as excision even though it's diagnostic rather than therapeutic.
