Operation Definition

Moving to its normal location, or other suitable location, all or a portion of a body part

Procedure Overview

Reposition procedures move a lower bone, or a fragment of one, from an abnormal location to its correct anatomical position, or to another location that will let it function properly. This is the category most fracture reductions fall into, along with corrective osteotomies performed to realign a bone that has healed crookedly or grown abnormally, and procedures that move a bone segment to a new site for reconstructive purposes.

These operations address displaced fractures of the pelvis, femur, tibia, fibula, patella, or foot bones, as well as deformities such as a bowed tibia or a malaligned metatarsal that needs to be cut and shifted into better alignment. Fixation devices like plates, screws, rods, or external fixators are frequently used alongside the repositioning to hold the bone in its new location while it heals.

Anatomy & Axis Detail

Femoral Shaft, Left

The left femoral shaft is the elongated middle portion of the thighbone lying between the proximal and distal ends, bearing the primary axial and torsional loads of the leg. Reposition addresses displaced diaphyseal fractures by moving fragments back into correct alignment, restoring length, rotation, and angulation before stabilization is performed. The shaft's close relationship to the deep femoral vessels and major thigh musculature means reduction must be carried out with attention to soft tissue protection and avoiding further displacement of fracture ends. As with the right side, this code applies strictly to the repositioning maneuver, with any nailing or plating captured under a separate procedure.

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.

Device: External Fixation Device

This is the general external fixation device value, used when pins or wires anchored in bone are connected to a stabilizing frame outside the body to hold a fracture or joint in position, without specifying a more particular frame configuration. It contrasts with the more specific External Fixation Device subtypes - Monoplanar, Ring, Hybrid, and Limb Lengthening - which describe the frame's geometry or added lengthening function.

Coding & Documentation

The operative note needs to document that a bone or bone fragment was moved to a different position, whether by closed manipulation or open surgical exposure, and should specify any fixation device left in place, since that device is captured as a separate value on the same code rather than a separate procedure. Coders must distinguish open versus percutaneous versus external approaches carefully, as this changes the approach value substantially. A common mistake is coding a simple cast application or splinting as Reposition when no manipulation of bone position actually occurred, and another is failing to capture the device value when hardware is placed during the same reduction.

Commonly Confused With

RepairRepair is the main point of confusion, since both can appear in fracture care documentation; Repair applies only when no formal repositioning or fixation of a fragment takes place.
FusionFusion is distinct because it targets a joint to eliminate motion permanently, while Reposition preserves the bone's normal mobility once healed.
DivisionDivision is sometimes confused with corrective osteotomy, but Division simply separates bone without relocating it, whereas Reposition requires the fragment to be moved to a new, more functional position.
