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

Fibula, Right

The right fibula is the slender, non-weight-bearing bone on the lateral side of the lower leg, contributing primarily to ankle stability through the lateral malleolus and to muscle attachment along its shaft. Because it bears little axial load, a portion of the fibula can often be excised, for a benign tumor, an osteochondroma, or infected bone, without significantly affecting leg function, and the fibula itself is sometimes harvested in segments for use as autograft elsewhere. The common peroneal nerve wraps around the fibular neck just below the knee, making surgeons cautious when excising bone from that proximal region to avoid nerve injury. Coding should distinguish the level involved, proximal, shaft, or distal near the ankle, and note whether the excised bone was discarded or used as graft material.

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.

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.

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.
