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 in this family involve putting in biological or synthetic material to physically stand in for all or part of a damaged bursa or, far more commonly, a ligament. The clearest example is anterior cruciate ligament (ACL) reconstruction, where a torn ACL is removed and replaced with a graft harvested from the patient's own patellar or hamstring tendon, from a donor, or occasionally a synthetic substitute, because the native ligament cannot be sutured back together and heal reliably.

These procedures are performed when a ligament tear is too severe, too chronic, or too central to joint stability for simple suturing to restore function - the knee, shoulder, and elbow are the joints where ligament replacement is most frequently needed. The goal is to give the joint a new structural cable capable of bearing the same mechanical loads as the original ligament, allowing patients to return to sports or daily activity with restored stability. Recovery is longer than for a simple repair, involving staged rehabilitation as the graft incorporates into the surrounding bone.

Anatomy & Axis Detail

Rib(s) Bursa and Ligament

Rib bursae and ligaments include the costotransverse and costovertebral ligaments along with intercostal connective tissue that anchors each rib to the spine and maintains the mechanical integrity of the thoracic cage during respiration. Replacement is uncommon and generally follows extensive trauma, tumor resection, or infection that destroys ligamentous support beyond what suture repair can address, particularly where rib stability affects overall chest wall function. Graft or synthetic material restores the tethering that keeps ribs properly aligned relative to the vertebrae, which matters for preserving normal respiratory excursion. Because multiple ribs and levels can be involved, documentation should specify which rib-associated ligament was replaced rather than treating the rib cage as a single uniform structure.

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: Nonautologous Tissue Substitute

Nonautologous Tissue Substitute refers to biologic material sourced from a donor or another species, such as an allograft or xenograft, used to replace a body part. It differs from Autologous Tissue Substitute by tissue origin outside the patient's own body, and from Synthetic Substitute by being biologic rather than manufactured material.

Coding & Documentation

Coders assign from this family when documentation clearly states that the native ligament or bursa was removed and a graft or prosthetic material was implanted to take its place - autograft, allograft, and synthetic ligament substitutes all qualify. The operative note should identify the graft source and confirm the original structure was excised rather than left in place. A common assignment error is coding Replacement when the surgeon actually augmented an intact ligament with additional material, which is Supplement; the deciding question is whether the native structure was taken out. Another pitfall is missing the correct body part value when a graft crosses two adjoining structures, such as ACL reconstruction touching both femoral and tibial attachment sites.

Commonly Confused With

SupplementSupplement is the operation most often mixed up with Replacement - Supplement reinforces a ligament that remains largely intact, while Replacement takes the damaged structure out and substitutes new material entirely.
RepairRepair is used instead when the native ligament can simply be sutured back together without any graft material.
ResectionResection differs in that no replacement material is introduced at all; the bursa or ligament is simply excised.
