CPT® Code 64823

The CPT® Code 64823 refers to a surgical procedure known as sympathectomy of the superficial palmar arch. This procedure involves the surgical division of sympathetic nerve connections associated with the superficial palmar arch, which is a critical vascular structure in the hand. The primary objective of this procedure is to enhance blood flow to the digits, particularly in patients suffering from severe ischemia, which can be caused by conditions such as Raynaud's syndrome, scleroderma, or other vascular diseases. The sympathectomy is performed to alleviate symptoms associated with these conditions, which may include pain, numbness, and color changes in the fingers due to inadequate blood supply. The procedure is typically executed through a transverse incision made in the distal palmar flexion crease, allowing for direct access to the superficial palmar arch. Utilizing microscopic techniques as necessary, the surgeon carefully divides the nerve connections and strips the adventitia from the arch, thereby interrupting the sympathetic nerve supply and promoting improved circulation to the affected areas of the hand.
