Cutting out or off, without replacement, all of a body part

Procedure Overview

This family covers the surgical removal of an entire bone or bony structure in the leg, foot, pelvis, or related lower-body skeletal segment, without putting anything back in its place. It applies to structures such as the femur, tibia, fibula, patella, pelvic bones, tarsals, metatarsals, and toe phalanges. Surgeons turn to it when a bone segment is destroyed by infection, riddled with tumor, so badly fractured that repair isn't feasible, or deformed beyond what osteotomy or reshaping could correct.

Because resection takes out the whole named bony part rather than a fragment, it is a bigger step than excision or debridement. Patients encounter it most often in the context of bone cancer (primary or metastatic), chronic osteomyelitis that has not responded to antibiotics, or severe joint destruction where the diseased bone end must be cleared away before a prosthesis or graft can be placed. Depending on the site, the surgeon may reconstruct with a graft, implant, or amputation-level closure in a separate, later procedure.

Anatomy & Axis Detail

Tarsal, Left

The left tarsal group comprises the calcaneus, talus, navicular, cuboid, and three cuneiforms, which together form the hindfoot and midfoot arch and bear the body's weight during standing and gait. Complete resection of a tarsal bone is reserved for aggressive infection such as osteomyelitis unresponsive to debridement, primary bone tumors, or severe avascular necrosis, since removing an entire bone from this tightly interlocked mosaic collapses the arch and typically demands adjacent joint fusion or structural bone grafting to restore a stable foot. Documentation should specify which individual tarsal bone was entirely removed, since the tarsals are coded separately and resection differs sharply in impact depending on whether the talus, calcaneus, or a smaller midfoot bone is involved.

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

The operative note has to state that an entire named bony part was removed, not a portion of it - documentation reading "partial resection" or "removed a segment of the shaft" points instead to Excision. Coders should confirm the specific bone or bone group from the ICD-10-PCS body part table (e.g., distal femur vs. entire femur can carry different values) and check whether the pathology report or op note supports a diagnosis - like tumor or osteomyelitis - that clinically justifies total removal.

A frequent error is defaulting to Resection whenever a large piece of bone is taken, when the correct read is Excision if any portion of the bone remains. Another is missing a same-operative-session Replacement or Supplement, which should be coded separately if a graft or device is placed after the bone is removed.

Commonly Confused With

ExcisionExcision is the closest neighbor and the most common miscode: it applies when only part of a bone is cut out, leaving the rest intact, while Resection requires the entire body part to be gone.
DetachmentDetachment is used instead when the resected structure is a limb or a portion cut off at a joint as an amputation-type procedure, which follows different body part values.
ReplacementReplacement should not be confused with Resection itself, though the two frequently occur together when a resected bone segment is immediately replaced with an implant or graft.
