CPT® Code 64822

Sympathectomy of the ulnar artery, designated by CPT® Code 64822, is a surgical procedure aimed at improving blood flow to the fingers by severing the sympathetic nerve connections associated with the ulnar artery. This procedure is particularly beneficial for patients suffering from severe ischemia, which can occur due to conditions such as Raynaud's syndrome, scleroderma, or other vascular diseases. The sympathetic nervous system plays a crucial role in regulating blood flow, and by interrupting these nerve connections, the procedure can alleviate symptoms associated with poor circulation in the digits. The technique involves careful dissection and manipulation of the ulnar artery, often utilizing an operating microscope to enhance precision and minimize damage to surrounding tissues. This procedure is part of a broader category of sympathectomies that may also include interventions on the digital arteries and the superficial palmar arch, each tailored to the specific vascular needs of the patient.
