CPT® Code 64866

The CPT® Code 64866 refers to the surgical procedure known as facial-spinal accessory nerve anastomosis, which is a reconstructive technique aimed at restoring function to the facial nerve. This procedure is typically indicated for patients who have suffered facial nerve damage, often due to trauma, surgical complications, or other medical conditions that impair facial nerve function. The anastomosis involves connecting the facial nerve to the spinal accessory nerve, which is responsible for certain motor functions in the neck and shoulder region. The surgical approach begins with an incision made in front of the ear, allowing access to the parotid gland and surrounding structures. The procedure requires careful dissection to identify the facial nerve as it exits the skull and to prepare the spinal accessory nerve for connection. By utilizing microsurgical techniques, the surgeon ensures that the anastomosis is performed with precision, aiming to restore facial movement and improve the patient's quality of life. This complex procedure underscores the intricate relationship between the facial and spinal accessory nerves and highlights the importance of surgical skill in achieving successful outcomes in nerve reconstruction.
