Sometimes daily motion can cause your back brace to shift out of place. If this happens, your doctor may prescribe you leg straps with an L0980 medical billing code. This is a code used to let insurance companies know what they are being billed for. The L0980 is a code used for prefabricated ready made pair of leg straps. These leg straps are meant to keep a brace in place. The L0980 is applied to leg straps that are considered "off the shelf". This means that the leg straps are not custom made, nor are they modified in any way to fit one specific patient.
