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

Lumbar Vertebra

Excision of a lumbar vertebra involves cutting out a portion of one of the five large vertebral bodies that bear most of the axial load in the lower back, most commonly performed to obtain a biopsy for suspected metastatic disease, infection, or primary bone tumor, or to remove a symptomatic bone spur or osteophyte impinging on neural structures. Because the lumbar vertebrae are massive relative to other spinal segments and sit close to the cauda equina and exiting nerve roots, even a partial excision demands careful attention to preserve spinal stability and avoid neurologic injury. This procedure is distinct from more extensive corpectomy or discectomy work, representing removal of a portion rather than the whole vertebral body, and does not include device placement. Documentation should specify the vertebral level, since L4 and L5 in particular carry biomechanical significance for the lumbosacral junction.

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

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.

Commonly Confused With

ExtirpationExcision is frequently confused with Extirpation, which applies to abnormal solid material like sequestered bone fragments or debris rather than a cut portion of otherwise viable bone.
ResectionIt's also confused with Resection, used when an entire bone or bony process is taken rather than just a part of it, and with Detachment, which applies specifically to amputation-type removal of a limb portion.
