CPT® Code 64778

Add-On Code

The procedure described by CPT® Code 64778 pertains to the excision of a neuroma affecting the digital nerve in each additional digit. Neuromas are benign growths that can develop on the digital nerves, which are responsible for providing sensation to the fingers and toes. In the hand, the median nerve branches into lateral and medial components, which further divide into digital nerves that innervate the fingers. Similarly, in the foot, the medial and lateral plantar nerves branch out to form digital nerves for the toes. When these nerves become damaged or irritated, they can form neuromas, leading to pain and discomfort. The excision procedure involves making a skin incision over the neuroma, carefully exposing and dissecting the neuroma from the surrounding tissue, and then removing it. After the excision, the incision is closed. It is important to note that this code is specifically used in conjunction with a primary procedure code, such as CPT® Code 64776, which is used for the excision of a neuroma from one or both digital nerves in the same finger or toe. CPT® Code 64778 is designated for each additional digit where a neuroma excision is performed.
