CPT® Code 28740

Arthrodesis of the midtarsal or tarsometatarsal joint, as described by CPT® Code 28740, refers to a surgical procedure aimed at fusing a single joint in the midfoot region. This procedure is typically indicated for patients suffering from severe, painful arthritis or those with congenital or acquired deformities affecting the midfoot. The goal of the surgery is to alleviate pain and restore function by permanently joining the bones of the affected joint, thereby eliminating movement that can cause discomfort. The surgical approach involves making a longitudinal incision over the targeted joint, ensuring that surrounding superficial nerves and blood vessels are carefully protected throughout the process. Once the joint is accessed, the surgeon meticulously removes all fibrous tissue and articular cartilage to prepare the bone surfaces for fusion. The articular surfaces are then shaped using an osteotome, and if necessary, a bone graft is harvested either locally or from donor sites such as the iliac crest or medial malleolus. The graft is tailored to fit the joint space and is secured in place with internal fixation devices, such as Steinmann pins, interfragmentary screws, or plates and screws, to maintain stability during the healing process. Finally, the incision is closed in layers, and a bulky dressing along with a splint is applied to support the foot during recovery.
