CPT® Code 64776

The procedure described by CPT® Code 64776 involves the excision of a neuroma affecting the digital nerve, which can occur in either one or both nerves of the same digit, whether it be a finger or a toe. Digital nerves are responsible for providing sensation to the fingers and toes, and they can become the site of painful benign growths known as neuromas. In the hand, the median nerve branches into lateral and medial components, which further divide into digital nerves that innervate the fingers. Specifically, the lateral digital nerve branches into three parts, with two serving the thumb and one serving the radial side of the index finger. The medial digital nerve also divides into common palmar digital nerves that innervate the remaining fingers. In the foot, the medial and lateral plantar nerves similarly branch out to form digital nerves for the toes, with each toe receiving two branches. When these nerves develop neuromas, they can cause significant discomfort, necessitating surgical intervention. The surgical procedure involves making a skin incision over the neuroma site, carefully exposing the neuroma, and then dissecting it free from the surrounding tissue before excising it. Finally, the incision is closed. This code specifically applies to the excision of a neuroma from one or both digital nerves in the same digit, while a different code, CPT® 64778, is used for excision of neuromas in additional fingers or toes.
