Summary & Overview
CPT 64610: Trigeminal Nerve Neurodestructive Injection
CPT code 64610 designates an image‑guided neurodestructive injection directed at part of the trigeminal nerve. It is used to interrupt sensory or motor function in the face and scalp, most commonly to treat severe trigeminal neuralgia (tic douloureux). Nationally, this procedure is clinically significant because it addresses a debilitating pain syndrome that can require specialized procedural pain management and may affect utilization patterns across outpatient surgical settings.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and common billing modifiers (provided in input). The publication summarizes available benchmarks and payment policy considerations, highlights coding and documentation points relevant to procedural and imaging guidance elements, and outlines implications for utilization management and prior authorization practices. Practical takeaways include how the procedure is described in coding terms, the clinical scenarios that commonly justify its use, and where to look for payer policy updates or medical necessity criteria. Data not available in the input will be noted where relevant.
Billing Code Overview
CPT code 64610 describes a neurodestructive injection procedure targeting part of the trigeminal nerve to ablate or disrupt nerve function. The service involves injecting a neurodestructive agent under imaging guidance at or near a branch of the trigeminal nerve to interrupt sensory and/or motor signals. This procedure is commonly performed to relieve severe facial pain from trigeminal neuralgia (tic douloureux) or to obstruct motor functions of the face or scalp when indicated.

Service type: Image‑guided neurodestructive nerve injection

Typical site of service: Outpatient procedural setting, ambulatory surgery center, or hospital outpatient department, performed under sterile technique with imaging guidance
Clinical & Coding Specifications
Clinical Context
A 67-year-old female with a 2-year history of refractory left-sided trigeminal neuralgia presents to a neurosurgical procedural suite after failing long-term medical therapy with carbamazepine and gabapentin and intolerable medication side effects. She reports paroxysmal lancinating facial pain in the V2 distribution triggered by speaking and light touch. Prior magnetic resonance imaging excluded a compressive vascular loop or mass. The care team elects to perform a percutaneous trigeminal nerve neurolytic injection under fluoroscopic or CT guidance to achieve pain relief.
The clinical workflow: the patient undergoes pre-procedure consent and anesthesia assessment, interruption of anticoagulants as indicated, and placement on a monitored procedural table. Conscious sedation or general anesthesia is provided per anesthesia and patient needs. Under sterile conditions, the interventional pain specialist or neurosurgeon advances a needle toward the foramen ovale (or appropriate percutaneous trigeminal approach) using fluoroscopy or CT guidance. After position confirmation with imaging and sensory/motor stimulation testing if indicated, a neurodestructive agent (e.g., glycerol, alcohol, or phenol) is injected to selectively destroy pain-conducting fibers. Immediate post-procedure monitoring occurs in recovery with assessment for facial numbness, corneal reflex, motor deficits, and signs of complications. Discharge instructions address wound care, activity restrictions, pain control, and follow-up for outcome assessment and possible repeat procedures if pain recurs.
