CPT® Code 20802

The procedure described by CPT® Code 20802 refers to the replantation of an arm that has undergone complete amputation. This complex surgical intervention is performed under general anesthesia to ensure the patient's comfort and safety throughout the operation. The process begins with the careful removal of any damaged tissue surrounding the amputation site, which is crucial for promoting healing and reducing the risk of infection. Following this, the ends of the amputated bones are meticulously trimmed to facilitate a more effective rejoining of the skeletal structure. This preparation is essential as it aids in aligning the soft tissues on either side of the wound, which is a critical step in the reattachment process. The surgeon then proceeds to suture together the various anatomical structures, including arteries, veins, nerves, muscles, and tendons, ensuring that blood flow and nerve function can be restored. In cases where there is a lack of skin coverage, a graft is utilized to protect the underlying tissues. Additionally, any exposed nerves, tendons, and joints may require coverage through a free-tissue transfer, which includes its own blood supply via associated arteries and veins. Finally, the amputation site is closed in layers, which is important for proper healing and minimizing scarring. This comprehensive approach underscores the complexity and precision required in performing a complete arm replantation.
