CPT® Code 29305

A hip spica cast is a specialized orthopedic device designed to immobilize one or both hips, providing essential support during the healing process of certain injuries or conditions affecting the hip area. The application of this cast begins with the placement of a stockinette, which is a soft, tubular fabric that is wrapped around the patient's torso, extending down over one or both legs. This stockinette serves as a protective layer against skin irritation from the cast material. Following the stockinette, padding is strategically placed to cushion the areas around the ribs, sacrum, and other pressure points, ensuring comfort and reducing the risk of pressure sores. The next step involves the use of plaster or fiberglass rolls, which are first immersed in water to activate their setting properties. After excess water is squeezed out, the saturated material is carefully wrapped around the torso and legs, forming the cast. Depending on the specific requirements of the patient's condition, the cast may extend only to the knee or all the way to the toes. As the casting material begins to set, it is smoothed and molded to ensure a snug fit. Additionally, a bar covered with cast material may be attached between the legs at the thigh level to enhance stability and support. For coding purposes, the appropriate CPT® code for a hip spica cast covering one leg is 29305, while 29325 is used for a hip spica cast that covers one leg and half of the other or both legs.
