CPT® Code 28315

The procedure described by CPT® Code 28315 refers to a sesamoidectomy of the first toe, which is classified as a separate procedure. The sesamoid bones are small, rounded bones located on the plantar aspect of the forefoot, specifically near the great toe, with one sesamoid bone positioned on either side of the first metatarsal head. These bones serve a critical function in the biomechanics of the foot; they act as pulleys that facilitate smooth tendon movement and provide a stable surface for tendons to glide over during foot movement. Additionally, the sesamoid bones play a significant role in weightbearing and assist in the elevation of the great toe bones during activities such as walking and running. When these sesamoid bones sustain fractures or become inflamed due to various conditions, surgical intervention may be required to alleviate pain and restore function. The surgical procedure involves making a skin incision directly over the affected sesamoid bone, followed by careful dissection of the surrounding soft tissues to access and excise the bone. This procedure is typically performed to relieve symptoms associated with sesamoiditis or other related pathologies affecting the sesamoid bones.
