CPT® Code 29325

A hip spica cast is a specialized orthopedic device used to immobilize one or both hips, providing necessary support and stabilization during the healing process. 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 applied to key areas, particularly around the ribs, sacrum, and other pressure points, to prevent discomfort and 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, ensuring that it conforms to the body shape. The cast can be designed to extend only to the knee or all the way to the toes, depending on the specific needs of the patient. 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, it is important to note that CPT® Code 29305 is used for a hip spica cast covering one leg, while CPT® Code 29325 is designated for a hip spica cast that covers one leg and half of the other or both legs.
