Add-On Code

Suture of nerve; requiring extensive mobilization, or transposition of nerve (List separately in addition to code for nerve suture)

The CPT® Code 64874 refers to the surgical procedure involving the suture of a nerve that necessitates extensive mobilization or transposition of the nerve. This procedure is typically required when a standard nerve suture cannot be performed due to tension on the nerve, which can occur when the nerve ends are not in close proximity to each other after an injury. In such cases, additional surgical techniques are employed to ensure that the nerve can be sutured without tension, which is critical for optimal healing and function. The mobilization process involves carefully freeing the nerve from surrounding tissues both distally and proximally, allowing for greater flexibility and movement of the nerve. If this mobilization alone does not suffice to achieve a tension-free repair, the nerve may be transposed, meaning it is rerouted through a different pathway, which may include creating a soft tissue tunnel. This procedure is often performed under microscopic visualization to enhance precision and minimize damage to surrounding structures. The complexity of this procedure underscores the need for careful planning and execution to ensure successful nerve repair and recovery.
