CPT® Code 64510

The procedure described by CPT® Code 64510 refers to the injection of an anesthetic agent into the stellate ganglion, which is part of the cervical sympathetic nervous system. This block is primarily utilized to diagnose or treat pain that is mediated by sympathetic nerves in various regions, including the head, neck, chest, or arm. Conditions that may warrant this procedure include reflex sympathetic dystrophy, which is a chronic pain condition, nerve injuries that can lead to persistent pain, herpes zoster (commonly known as shingles), and intractable angina, which is severe chest pain due to heart-related issues. During the procedure, the healthcare provider palpates the front of the neck, specifically in the area around the voice box, to accurately locate the stellate ganglion for needle insertion. After preparing the neck, the provider inserts the needle through the skin and advances it into the deeper tissues until it reaches the targeted area. Once the needle is correctly positioned, an anesthetic agent is injected to block the sympathetic nerve signals. Following the injection, the patient is monitored for a period of 10 to 20 minutes to assess the effectiveness of the anesthetic and to observe for any immediate reactions.
