CPT® Code 29355

The CPT® Code 29355 refers to the application of a long leg cast that extends from the thigh to the toes, specifically designed for use as a walker or ambulatory type. This procedure involves several steps to ensure that the cast is both functional and comfortable for the patient. Initially, a stockinette is placed over the area of the leg that will be casted, providing a protective layer against the skin. Following this, padding is applied over the stockinette to enhance comfort and prevent irritation. The casting material, which can be either plaster or fiberglass, is then prepared by immersing it in water until it is fully saturated. After excess water is gently squeezed out, the casting material is wrapped around the leg, typically starting from the distal (far) end and moving towards the proximal (near) end. This method allows for a secure fit that conforms to the shape of the leg. The cast is then smoothed and molded to ensure it provides adequate support while allowing for mobility. It is important to note that this specific code is used for casts that are designed to allow ambulation, as opposed to a standard long leg cast, which does not facilitate walking. The walker component of the cast is made from a prefabricated heel constructed of a non-slip material, which is affixed to the bottom of the cast. This design includes additional strips of plaster applied to the base of the cast to enhance stability. The walker is carefully positioned and molded into the cast to ensure a secure attachment, allowing the patient to walk safely while wearing the cast.
