CPT® Code 64820

Sympathectomy of the digital arteries, as described by CPT® Code 64820, is a surgical procedure aimed at improving blood flow to the fingers by targeting the sympathetic nerve connections associated with the digital arteries. This procedure is particularly relevant for patients suffering from severe ischemia, which can occur due to conditions such as Raynaud's syndrome, scleroderma, or other vascular diseases that impair blood circulation to the digits. The procedure involves making a zigzag incision at the base of the finger, which is then extended into the palm. The surgeon utilizes an operating microscope to enhance visibility and precision during the operation. The common digital artery is carefully separated from the adjacent digital nerve, and the adventitia, or outer layer of the artery, is stripped away, starting from the superficial palmar arch and continuing distally along the artery. This dissection effectively severs the sympathetic connections, which can alleviate symptoms associated with poor blood flow. After the completion of the procedure, the incisions are meticulously closed in layers to promote optimal healing. It is important to note that CPT® Code 64820 is reported for each digit on which the sympathectomy is performed, allowing for accurate coding and billing for the surgical intervention.
