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

Toe Phalanx, Left

The phalanges of the left toes make up the skeletal segments of each digit, the great toe having a proximal and distal phalanx and the lesser toes an additional middle phalanx, all subject to the repetitive pressure of shoe wear and weight-bearing. Excision takes out a portion of one of these small bones without removing the entire toe, a technique used in hammertoe or claw toe correction to shorten and straighten a digit, or to remove a bone spur or a segment affected by osteomyelitis. Given how compact these bones are, surgeons rely on careful intraoperative imaging, and coders must record the specific toe and phalangeal level involved, since arthrodesis or other adjunctive procedures are frequently performed alongside the excision to stabilize the digit afterward.

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

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.
