CPT® Code 29345

The procedure described by CPT® Code 29345 involves the application of a long leg cast, which extends from the thigh down to the toes. This type of cast is typically used to immobilize the leg for the treatment of fractures, severe sprains, or other injuries that require stabilization of the entire leg. The process begins with the application of a stockinette, which serves as a protective layer over the skin. Following this, padding is added to provide cushioning and prevent irritation from the cast material. The next step involves the use of plaster or fiberglass rolls, which are immersed in water to activate their setting properties. Once saturated, excess water is squeezed out to ensure the material is not overly wet, which could affect its integrity. The plaster or fiberglass is then wrapped around the leg, starting from the distal (far) end and moving towards the proximal (near) end, ensuring that the cast conforms closely to the contours of the leg. The final steps include smoothing and molding the cast to ensure a snug fit, which is crucial for effective immobilization. It is important to note that this code specifically refers to a long leg cast that is not designed for walking or ambulation; for walking casts, a different code (CPT® Code 29355) is used, which includes additional features such as a prefabricated heel for stability and safety during ambulation.
