Summary & Overview
CPT 64740: Lingual Nerve Transection for Facial Pain
CPT code 64740 denotes a surgical lingual nerve transection performed to diminish sensation and relieve facial pain. As an invasive peripheral nerve procedure, it is clinically significant for select patients with refractory neuropathic or intractable facial pain where conservative therapies have failed. Nationally, use of this code is uncommon and typically concentrated in surgical practices and hospital settings that manage complex craniofacial pain.
Payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage and payment policies vary across commercial plans and Medicare, affecting utilization, prior authorization, and facility settings.
Readers will find a concise overview of clinical context for 64740, typical sites of service, and payer coverage considerations. The publication summarizes benchmarking metrics where available, highlights salient policy or coding updates affecting reimbursement and documentation, and outlines common billing modifiers and administrative considerations for claims processing. The content is intended to inform revenue cycle, coding, and clinical stakeholders about coding, billing, and payer interactions related to this specific peripheral nerve surgical procedure.
Billing Code Overview
CPT code 64740 describes a surgical procedure in which the provider transects or forcibly tears the lingual nerve to reduce facial pain by diminishing sensation. This procedure is a form of peripheral nerve intervention intended to provide pain relief when other treatments are insufficient.
-
Service type: Surgical peripheral nerve procedure for pain management
-
Typical site of service: Operating room or other surgical suite where minor-to-moderate surgical interventions on cranial or oral nerves are performed

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting with chronic, severe unilateral or bilateral neuropathic facial pain localized to the anterior two-thirds of the tongue or floor of mouth, refractory to conservative therapy (pharmacologic pain management, nerve blocks, or less invasive neurosurgical procedures). The patient has undergone diagnostic evaluation including history, neurologic exam, and imaging as indicated to exclude structural lesions. After multidisciplinary review and informed consent addressing expected sensory loss and risks, the provider performs a surgical transection or avulsion of the lingual nerve to reduce afferent nociceptive input and relieve intractable neuropathic pain.
Typical workflow:
-
Preoperative assessment by the operating surgeon (oral and maxillofacial surgeon, otolaryngologist, or neurosurgeon), including review of prior treatments, medication reconciliation, and documentation of pain severity and prior responses.
-
Preoperative counseling and consent documenting indication, anticipated permanent sensory deficit of the ipsilateral anterior tongue, alternative treatments, and potential complications.
-
Procedure performed in an appropriate surgical setting (ambulatory surgery center or hospital operating room) under local anesthesia with sedation or general anesthesia, with intraoperative identification and deliberate transection/avulsion of the lingual nerve.
-
Immediate postoperative monitoring for airway, bleeding, and anesthetic recovery; discharge planning for outpatient cases or admission if indicated.
-
Postoperative follow-up to assess pain relief, wound healing, sensory changes, and management of complications such as dysesthesia, infection, or persistent neuropathic pain.
