CPT® Code 64713

The procedure described by CPT® Code 64713 refers to neuroplasty of a major peripheral nerve, specifically targeting the brachial plexus in the arm or leg through an open surgical approach. The brachial plexus is a complex network of nerves that originates from the spinal cord and extends to the shoulder, arm, and hand, facilitating motor and sensory functions in these areas. Injuries to the brachial plexus can arise from various causes, including blunt trauma often seen in contact sports, automobile accidents, or falls. Additionally, such injuries may occur during childbirth or result from conditions like inflammation or the presence of tumors. Damage to this nerve network can lead to the formation of scar tissue and adhesions, which can entrap and compress the nerves, resulting in pain, weakness, or loss of function in the affected limb. The surgical procedure involves a supraclavicular approach to access the proximal aspect of the brachial plexus, where the omohyoid muscle is divided to facilitate exposure. During the operation, electrophysiological tests may be conducted to evaluate the function of the exposed nerves and nerve roots, helping to identify which nerves are under compression. The surgeon then meticulously dissects the compressed nerves free from the surrounding scar tissue and other obstructive structures. After ensuring that the affected nerves are completely liberated, the overlying soft tissues are carefully closed in layers to promote healing.
