The CPT® Code 20697 refers to the application of a multiplane unilateral external fixation device, which is a specialized orthopedic procedure used to stabilize fractures or deformities of the bone. This procedure employs a stereotactic computer-assisted adjustment system, which enhances the precision of the fixation process. The term "multiplane" indicates that the external fixation device can be adjusted in multiple planes, allowing for comprehensive correction of complex intra-articular fractures or deformities. The use of imaging during the procedure aids in accurately positioning the external fixator components, which include struts, rings, bolts, cubes, and springs, collectively known as the spatial frame. The spatial frame is strategically placed around the affected bone and is secured using pins or wires that penetrate through the rings and/or struts into the bone itself. This external fixation method is particularly advantageous as it allows for dynamic stabilization, meaning that it can accommodate movement of the involved joint while still providing the necessary support for healing. The adjustments made to the spatial frame are facilitated by computer software, which enables the physician to make precise modifications to the alignment of the bone. This tailored approach ensures optimal correction of the deformity based on a patient-specific adjustment schedule. It is important to note that the exchange of a strut, which involves both the removal and replacement of the strut, is reported separately under this code for each strut that is exchanged, distinguishing it from the initial application and adjustments of the external fixation device.
