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.

The application of a long leg cast (thigh to toes) using CPT® Code 29355 is indicated for various conditions that require immobilization of the leg while allowing for ambulation. These indications may include:
The procedure for applying a long leg cast using CPT® Code 29355 involves several detailed steps to ensure proper application and functionality. The first step is the application of a stockinette over the area of the leg that is to be casted. This stockinette serves as a protective barrier between the skin and the casting material. Next, padding is placed over the stockinette to provide additional comfort and to prevent skin irritation from the cast. Once the padding is in place, the casting material, either plaster or fiberglass, is prepared by immersing it in water until it is fully saturated. After soaking, excess water is gently squeezed out to ensure that the material is not overly wet, which could affect its setting properties. The saturated casting material is then wrapped around the leg, starting from the distal aspect (the toes) and moving towards the proximal aspect (the thigh). This technique allows for a secure fit that conforms to the leg's anatomy. As the material is applied, it is smoothed and molded to ensure that it provides adequate support while maintaining comfort for the patient. For the walker or ambulatory type cast, a prefabricated heel made of a non-slip material is attached to the bottom of the cast over the heel area. This is crucial for allowing the patient to walk safely while wearing the cast. Several strips of plaster are applied to the bottom of the cast to enhance stability. The walker is then carefully positioned on the bottom of the cast, and the plaster is molded around the walker to secure it in place. A second strip of plaster is placed in a groove in the middle of the walker and wrapped around the top of the cast over the foot to ensure that the walker is firmly attached to the cast, providing the necessary support for ambulation.
After the application of the long leg cast, it is essential to monitor the patient for any signs of complications, such as swelling, discomfort, or skin irritation. Patients are typically advised on how to care for the cast, including keeping it dry and avoiding any activities that could compromise its integrity. Follow-up appointments may be scheduled to assess the healing process and to make any necessary adjustments to the cast. Patients should also be educated on the importance of reporting any unusual symptoms, such as increased pain or changes in circulation, to their healthcare provider promptly. The expected recovery time will vary depending on the underlying condition being treated, but the cast will generally remain in place until adequate healing has occurred, as determined by the physician.
