CPT® Code 28305

The procedure described by CPT® Code 28305 involves an osteotomy of the tarsal bones, specifically excluding the calcaneus or talus, and includes the use of an autograft. An osteotomy is a surgical procedure that involves cutting and reshaping bones to correct deformities or misalignments. In this case, the focus is on the navicular, cuboid, and cuneiform bones, which are critical components of the midfoot structure. This procedure is typically indicated for patients with congenital or acquired foot deformities, such as pes cavus, which is characterized by an excessively high arch. The term 'autograft' refers to the use of the patient's own bone tissue, which is harvested and then used to fill the defect created by the osteotomy. This approach is beneficial as it reduces the risk of rejection and complications associated with foreign graft materials. The surgical technique may involve an opening wedge osteotomy, where the bone is cut and spread apart to create a space that is then filled with the harvested bone graft. This method aims to restore proper alignment and function of the foot, ultimately improving the patient's mobility and quality of life.
