CPT® Code 25210

The carpus, commonly referred to as the wrist joint, is composed of eight small bones arranged in two rows, with four bones in each row. The proximal row consists of the pisiform, triquetrum, lunate, and scaphoid (also known as the navicular) bones, while the distal row includes the hamate, capitate, trapezoid, and trapezium bones. The procedure described by CPT® Code 25210 involves the excision of a single carpal bone. This surgical intervention is typically indicated when there is a need to remove a bone due to various conditions affecting the wrist. During the procedure, a longitudinal incision is made on the dorsal aspect of the wrist, directly over the carpal bone designated for excision. To facilitate access, traction is applied to the fingers, allowing for better exposure of the carpal bone while ensuring that surrounding ligaments are preserved. A rongeur, a surgical instrument designed for cutting bone, is utilized to remove the middle portion of the targeted bone, which results in the bone collapsing inward. Subsequently, the remaining proximal and distal portions of the bone are carefully excised. After the excision is complete, the incision is meticulously closed in layers, and the wrist is immobilized in a cast to promote healing and stability post-surgery.
