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
Pelvic Bone, Right
The right pelvic bone, formed by the fused ilium, ischium, and pubis, is excised in part most often to obtain a bone marrow or tumor biopsy from the iliac crest, to harvest autologous bone graft for use elsewhere in the body, or to remove a localized lesion such as an osteochondroma or area of infection. The iliac crest in particular is a favored biopsy and graft donor site because it offers accessible cortical and cancellous bone without disrupting a weight-bearing joint surface. Because the pelvis forms part of the ring that transmits load between the spine and lower extremities, and because major vessels and nerves course along its inner and outer surfaces, the surgeon must carefully plan the excision site to avoid destabilizing the pelvic ring or injuring structures such as the femoral or sciatic nerve. Laterality and the specific pelvic subregion should be documented precisely.
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.
