CPT® Code 15840

The procedure described by CPT® Code 15840 involves the use of a graft to address facial nerve paralysis. Specifically, this code refers to the harvesting and transplantation of a free fascia graft, which is a type of connective tissue that provides structural support. The fascia is typically obtained from the fascia lata, a layer of tissue located in the thigh region. This harvested graft is then carefully transplanted to the facial area where paralysis has occurred. The surgical process includes suturing the graft beneath the skin to facilitate partial reanimation of the facial muscles that have been affected by paralysis. This procedure aims to restore some degree of movement and function to the face, improving the patient's appearance and quality of life. It is important to note that alternative codes exist for different types of grafts and techniques, such as a free muscle graft (CPT® Code 15841), a free muscle flap with microsurgical technique (CPT® Code 15842), and a regional muscle transfer (CPT® Code 15845), each indicating specific methods and materials used in the surgical intervention.
