CPT® Code 64734

Transection or avulsion of the infraorbital nerve, as described by CPT® Code 64734, refers to a surgical procedure that involves severing or removing a portion of the infraorbital nerve. This procedure is primarily performed to alleviate chronic pain conditions that may be associated with nerve dysfunction or irritation. The infraorbital nerve is a significant branch of the maxillary nerve, which is part of the trigeminal nerve system responsible for sensory innervation to various facial regions. Specifically, the infraorbital nerve provides sensory branches to the lower eyelid, the side of the nose, and the upper lip. The surgical approach to this nerve can be conducted either intraorally or extraorally, depending on the specific clinical scenario and the surgeon's preference. In the extraoral approach, an incision is typically made along a natural skin crease in the infraorbital rim to facilitate access to the nerve. The procedure aims to disrupt the nerve's function, which can lead to a reduction in pain perception in the areas it innervates. This intervention is particularly relevant for patients suffering from conditions such as neuropathic pain or other chronic pain syndromes where conservative treatments have failed.
