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
Metatarsal, Left
The left metatarsals form the long bones of the mid-foot, connecting the tarsal bones to the toes and absorbing forceful loading during walking and running. Excision of a portion of one of these bones is performed for conditions such as an enchondroma, a stress-related nonunion fragment, or infected bone requiring debridement short of full removal. Because the metatarsals vary in length and load distribution, with the first bearing the greatest axial force and the fifth prone to avulsion injury at its base, the specific bone and segment excised should be clearly recorded. The procedure leaves the remainder of the bone intact, distinguishing it from resection, and surgeons must weigh preservation of the transverse arch against the need for adequate margins when tumor or infected tissue is present.
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.
