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
Tarsal, Right
The tarsal bones of the right foot, the talus, calcaneus, navicular, cuboid, and three cuneiforms, make up the hindfoot and midfoot and form a complex of joints essential for weight transfer and gait adaptation over uneven surfaces. Excision of a portion of one of these bones is commonly performed for a symptomatic osteophyte such as those seen in midfoot arthritis, a coalition between adjacent tarsals, or a benign cyst or lesion identified on imaging. Because these bones interlock tightly and share numerous small articular facets, even a limited excision can shift the mechanics of the subtalar or midtarsal joints if not planned carefully. Documentation should specify exactly which tarsal bone was involved, since ICD-10-PCS assigns separate body part values to the talus and calcaneus versus the remaining tarsals grouped together.
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.
