Summary & Overview
CPT 64822: Ulnar Artery Sympathectomy for Ischemic Pain
CPT code 64822 describes surgical removal or destruction of sympathetic nerves of the ulnar artery to relieve pain or improve blood flow in patients with narrowed or vasospastic vessels. This procedure is clinically significant for patients with severe ischemia or refractory vasospasm of the hand or forearm where improving distal perfusion can preserve tissue and reduce pain. Nationally, the code captures a specialized neurovascular intervention relevant to vascular surgery, hand surgery, and peripheral nerve specialists.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and typical sites of service, plus what to expect from payer coverage policies and benchmark reporting where available. The publication outlines common billing and coding considerations for 64822, summarizes typical clinical indications, and highlights how payers and Medicare approach reimbursement for specialized sympathectomy procedures. Where input data is incomplete, the report notes missing elements and focuses on national relevance rather than state-specific practices.
Billing Code Overview
CPT code 64822 describes a surgical procedure in which the provider removes or destroys sympathetic nerves of the ulnar artery. The procedure is performed to relieve ischemic pain or to increase blood flow in a limb affected by narrowed or vasospastic blood vessels.
-
Service type: Surgical neurovascular sympathectomy targeting the ulnar artery to improve distal perfusion and reduce pain.
-
Typical site of service: Ambulatory surgical center or hospital operating room, depending on patient condition and clinical setting.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 52-year-old male with progressive ischemic pain, cold intolerance, and digital ulceration of the hand due to severe vasospasm and chronic vasculopathy affecting the ulnar artery distribution. After conservative measures (smoking cessation, vasodilator medication, and wound care) fail and vascular imaging confirms focal sympathetic-mediated vasoconstriction of the ulnar artery, the vascular or hand surgeon performs a targeted sympathectomy of the ulnar artery to interrupt sympathetic fibers and improve distal blood flow. The clinical workflow includes preoperative vascular assessment (Doppler ultrasound or angiography), informed consent discussing risks/benefits and alternatives, intraoperative monitoring in an outpatient surgery center or inpatient operating room depending on comorbidity, surgical exposure of the ulnar artery at the wrist or forearm, identification and removal or chemical destruction of the sympathetic fibers along the artery, hemostasis, closure, and postoperative monitoring of perfusion and wound healing. Typical postprocedure care includes analgesia, limb warming, monitoring for hematoma or infection, and follow-up vascular assessment to document improved blood flow and symptom relief.
