Injection, anesthetic agent; facial nerve

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The injection of an anesthetic agent into the facial nerve (CPT® Code 64402) is indicated for various conditions that may involve pain or dysfunction associated with the facial nerve. The primary indications include:

  • Muscle Spasms The injection may be performed to treat involuntary muscle contractions or spasms in the facial region.
  • Disruption of Sensory Transmission This procedure can be utilized to interrupt the transmission of sensory stimuli, providing relief from pain or discomfort associated with facial nerve conditions.

2. Procedure

The procedure for injecting an anesthetic agent into the facial nerve involves several key steps, which are detailed as follows:

  • Preparation The area over the facial nerve is first cleansed thoroughly to minimize the risk of infection. This step is crucial for ensuring a sterile environment during the injection.
  • Identification of the Injection Site The healthcare provider identifies the precise location of the facial nerve, which is essential for the effectiveness of the injection. This may involve palpation or the use of imaging techniques to ensure accuracy.
  • Injection of Anesthetic Agent Once the site is prepared and identified, an anesthetic agent is injected into the facial nerve. The injection technique may vary depending on the specific condition being treated and the provider's preference.
  • Assessment of Pain Relief After the injection, the patient is typically asked to assess the degree of pain relief experienced. This feedback is important for evaluating the effectiveness of the procedure and determining any further treatment needs.

3. Post-Procedure

Following the injection of the anesthetic agent into the facial nerve, patients may experience immediate relief from symptoms, although the duration of this relief can vary. It is important for patients to be monitored for any adverse reactions or complications following the procedure. Patients may be advised to avoid strenuous activities for a short period and to follow any specific post-procedure care instructions provided by their healthcare provider. Additionally, follow-up appointments may be scheduled to assess the long-term effectiveness of the treatment and to determine if further interventions are necessary.
