CPT® Code 64632

The procedure described by CPT® Code 64632 involves the destruction of the plantar common digital nerve using a neurolytic agent, typically ethyl alcohol. This intervention is primarily aimed at alleviating pain in the interdigital space, which is often associated with conditions such as Morton's neuroma. Morton's neuroma is a painful condition that affects the nerves between the toes, leading to discomfort and a burning sensation. The procedure is performed with the patient in a supine position, ensuring comfort and accessibility to the foot. The knee is flexed and supported with a pillow, while the foot is kept in a relaxed neutral position to facilitate the accurate placement of the needle. The clinician palpates the interdigital spaces to identify areas of tenderness or fullness, which may indicate the presence of a neuroma. The technique involves careful insertion of the needle at a specific anatomical location, ensuring that the neurolytic agent is delivered precisely to the target nerve. The use of a neurolytic agent like ethyl alcohol results in chemical neurolysis, which effectively disrupts the nerve's function by causing dehydration, necrosis, and the precipitation of protoplasm, ultimately leading to pain relief for the patient.
