CPT® Code 28730

The procedure described by CPT® Code 28730 refers to the surgical technique known as arthrodesis, specifically targeting the midtarsal or tarsometatarsal joints. This surgical intervention is primarily indicated for patients suffering from severe, painful arthritis or those with congenital or acquired deformities affecting the midfoot region. The goal of the procedure is to fuse multiple joints in the midfoot to alleviate pain and restore function. During the operation, a longitudinal incision is made over the affected joints, ensuring careful handling of superficial nerves and blood vessels to minimize complications. The surgeon then exposes the joint by removing all fibrous tissue and articular cartilage, which may involve resecting bone in cases of significant deformity. The articular surfaces are meticulously prepared 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. This graft is shaped and placed into the joint space to facilitate fusion. To ensure stability during the healing process, internal fixation devices, such as Steinmann pins, interfragmentary screws, or plates and screws, are utilized. The procedure concludes with layered closure of the incisions and the application of a bulky dressing and splint to support the foot during recovery. It is important to note that CPT® Code 28730 should be used when the procedure is performed without an accompanying osteotomy, while CPT® Code 28735 is designated for cases where an osteotomy is also performed to address conditions like flatfoot deformity.
