CPT® Code 28116

The procedure described by CPT® Code 28116 refers to an ostectomy, specifically the excision of a tarsal coalition. A tarsal coalition is characterized by an abnormal connection or fusion between two or more tarsal bones in the foot, which can significantly restrict the normal range of motion. This condition may arise from various causes, with congenital factors being the most common; however, it can also develop as a result of acquired conditions such as infections, arthritis, or traumatic injuries. Clinically, individuals with a tarsal coalition may experience a range of symptoms, including pain during ambulation or standing, fatigue in the legs, muscle spasms, flatfoot deformity, limping, and stiffness in the foot and ankle. The surgical approach to address this condition is contingent upon the specific tarsal bones involved in the coalition. During the procedure, the abnormal connections—whether they consist of bone, cartilage, or fibrous tissue—are surgically excised. To promote proper healing and restore function, surrounding fat and/or muscle tissue is interposed between the affected bones. Finally, the overlying soft tissues are meticulously closed in layers, and the foot is immobilized in a cast to ensure stability during the recovery process.
