The CPT® Code 64402 refers to the procedure of injecting an anesthetic agent into the facial nerve, which is also known as cranial nerve VII (CN VII). This procedure is categorized as a nerve block and can serve both diagnostic and therapeutic purposes. The facial nerve is a mixed nerve, meaning it has both motor and sensory functions, and plays a crucial role in facilitating facial expressions. The injection of an anesthetic agent into this nerve can be performed to alleviate muscle spasms or to disrupt the transmission of sensory stimuli, thereby providing relief from associated pain or discomfort. The procedure typically involves cleansing the skin over the area of the facial nerve before the anesthetic is administered. This targeted approach aims to provide effective pain management and improve the quality of life for patients experiencing conditions related to the facial nerve.
