Operation Definition

Putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part

Procedure Overview

Replacement procedures put in biological or synthetic material that physically takes over the role of all or part of a lower bone. This includes structural bone grafts, cadaver bone allografts, and synthetic bone substitutes used to rebuild a portion of the pelvis, femur, tibia, fibula, or foot bones after tumor resection, severe trauma, or bone loss from infection.

These procedures are performed when a segment of bone is missing or so damaged that it can no longer support the body's structure or function on its own, and simply repairing or repositioning the remaining bone isn't enough. A patient who has had a tumor removed from the femoral shaft, for example, may need the resulting gap filled with a structural allograft to restore the bone's load-bearing capacity.

Anatomy & Axis Detail

Pelvic Bone, Right

The right pelvic bone, comprising the ilium, ischium, and pubis fused around the acetabulum, forms half of the bony pelvic ring and anchors the hip joint along with major muscle attachments for the trunk and thigh. Replacement of this body part occurs when extensive bone loss from tumor resection, severe comminuted fracture, or failed prior reconstruction requires substituting a structural or custom implant for the native pelvic bone, distinct from acetabular component replacement performed during routine hip arthroplasty. Given the pelvis's proximity to major vessels and the lumbosacral plexus, these reconstructions are typically extensive, and documentation should make clear whether the replaced segment is the pelvic bone itself rather than the acetabulum, which is coded separately.

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: Synthetic Substitute

Synthetic Substitute designates a device made from manufactured, non-biologic material, such as mesh or prosthetic components, used to replace or augment a body part. It is distinguished from the two tissue substitute categories by its artificial composition, which carries different considerations for integration and long-term durability than biologic grafts.

Coding & Documentation

Documentation must describe material being put in that takes over the physical role of the bone segment - not material that merely reinforces existing bone, which would be Supplement instead. The type of graft or substitute material and the specific bone segment addressed both need to be clear in the operative note. A frequent error is coding Replacement when bone graft is used to fill a defect but the native bone structure is still largely intact and functional, which points toward Supplement rather than Replacement; another is confusing joint replacement procedures, which are coded to the Lower Joints body system, with bone-segment replacement coded here.

Commonly Confused With

SupplementSupplement is the closest and most frequently confused root operation, since both can involve grafting material into bone; the distinguishing factor is whether the material takes the place of a missing or resected bone segment (Replacement) or reinforces bone that is still structurally present (Supplement).
InsertionInsertion is distinct because it covers placing a device that doesn't physically substitute for bone tissue, such as a spacer.
RepositionReposition is unrelated in purpose, since it moves existing bone rather than replacing missing bone with new material.
