CPT® Code 28755

The procedure described by CPT® Code 28755 refers to the surgical technique known as arthrodesis of the great toe, specifically targeting the interphalangeal joint. Arthrodesis is a surgical procedure that involves the fusion of a joint, which is achieved by eliminating the articular cartilage and stabilizing the bones to promote bone growth across the joint space. In this case, the focus is on the interphalangeal joint of the great toe, which is the joint located between the proximal and distal phalanges of the toe. The procedure is performed through an incision made on the lateral side of the great toe, ensuring that surrounding nerves and blood vessels are carefully protected during the operation. The surgical steps include exposing the joint, excising the articular cartilage, and preparing the bone surfaces for fusion. This is accomplished by using an osteotome to scale the articular surfaces, which allows for the exposure of cancellous bone. To achieve stability and promote healing, internal fixation devices such as pins, screws, staples, or small plates are utilized to hold the bones together across the joint. After the fixation is secured, the incision is closed, and a bulky dressing is applied to protect the surgical site. It is important to note that CPT® Code 28755 is specifically designated for the fusion of the interphalangeal joint, while CPT® Code 28750 is used for the fusion of the metatarsophalangeal joint of the great toe.
