Summary & Overview
CPT 64809: Thoracolumbar Sympathetic Nerve Procedure
CPT code 64809 represents a thoracolumbar sympathetic nerve procedure in which a portion of the sympathetic chain is removed or destroyed to relieve pain or improve blood flow in patients with narrowed blood vessels. Nationally, this code captures interventions for vascular insufficiency and certain neuropathic pain conditions where modulation of sympathetic outflow is clinically indicated. Payers commonly covering such procedures include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
This publication provides clinicians, billing professionals, and policy analysts with a concise view of CPT code 64809. Readers will find: a clinical description and typical settings for the procedure; the list of major payers considered in the analysis; and what to expect in benchmarking and policy context. Where specific contractual or coding details are not provided in the source input, the publication notes that data are not available in the input. The focus is national, summarizing clinical purpose and service context relevant to reimbursement, utilization review, and coding workflows.
Billing Code Overview
CPT code 64809 describes a surgical procedure in which the provider removes or destroys a portion of the thoracolumbar sympathetic nerve, part of the sympathetic chain. The procedure is intended to relieve pain or increase blood flow in patients with narrowed blood vessels and is a targeted neuroablative intervention on the sympathetic nervous system.
-
Service type: Neuroablative sympathetic nerve procedure
-
Typical site of service: Hospital operating room or ambulatory surgical center
Clinical & Coding Specifications
Clinical Context
A typical patient is a middle-aged to older adult with chronic, predominantly unilateral lower extremity ischemic pain or severe peripheral vascular disease causing rest pain and/or nonhealing ischemic ulcers. The patient has been evaluated by vascular surgery and pain management; conservative measures (smoking cessation, pharmacotherapy, exercise therapy, endovascular or open revascularization where appropriate) are either contraindicated, unsuccessful, or insufficient to relieve ischemic pain. Diagnostic workup includes vascular imaging (arterial duplex ultrasound, CT angiography or MR angiography), vascular laboratory studies, and consultation documenting focal arterial narrowing or occlusive disease. After multidisciplinary review, the patient is scheduled for a thoracolumbar sympathetic neurolysis/ectomy to interrupt sympathetic efferent fibers supplying the lower extremity to improve distal blood flow and relieve ischemic pain.
Pre-procedure workflow includes informed consent, review of anticoagulation status, baseline neurologic and vascular examination, and appropriate pre-procedure imaging review. The procedure is typically performed in an ambulatory surgery center or hospital operating room under monitored anesthesia care or general anesthesia with fluoroscopic or CT guidance. Post-procedure workflow includes recovery monitoring, neurovascular checks of the lower extremities, pain assessment, and outpatient follow-up with vascular surgery and pain management to assess wound healing, pain reduction, and limb perfusion.
