CPT® Code 20805

The procedure described by CPT® Code 20805 refers to the surgical replantation of a forearm that has been completely amputated, specifically between the wrist and elbow. This complex surgical intervention is performed under general anesthesia to ensure the patient is fully unconscious and pain-free during 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, namely the radius and ulna, are meticulously trimmed to facilitate a proper alignment and connection. This preparation is essential as it aids in the subsequent steps of suturing the soft tissues, including arteries, veins, nerves, muscles, and tendons, which are all critical for restoring function and sensation to the limb. In cases where there is a lack of skin coverage, a graft is utilized to protect the underlying structures. 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 surgical site is closed in layers to ensure optimal healing and support for the reattached structures.
