CPT® Code 20696

Application of multiplane (pins or wires in more than 1 plane), unilateral, external fixation with stereotactic computer-assisted adjustment (eg, spatial frame), including imaging; initial and subsequent alignment(s), assessment(s), and computation(s) of adjustment schedule(s)

The CPT® Code 20696 refers to the application of a multiplane unilateral external fixation device that utilizes stereotactic computer-assisted adjustment, which is a sophisticated method of aligning and stabilizing fractures or deformities. This procedure is particularly beneficial for complex intra-articular fractures or deformities, where traditional fixation methods may not provide adequate support or alignment. The term 'multiplane' indicates that the external fixation device can be adjusted in multiple planes, allowing for simultaneous correction of various axes of a fracture or deformity. This dynamic type of fixation not only stabilizes the affected area but also permits mobility of the involved joint, which is crucial for patient recovery and rehabilitation. During the procedure, a spatial frame, which consists of external fixator components such as struts, rings, bolts, cubes, and springs, is positioned around the bone that requires treatment. Pins or wires are then inserted through the rings and/or struts and into the bone to secure the spatial frame in place. The precise alignment of the bone is achieved through the use of computer software, which enables the physician to make accurate adjustments based on a patient-specific adjustment schedule. This level of customization is essential for achieving optimal correction of the deformity. The code 20696 encompasses not only the initial application of the external fixation device but also any subsequent alignments, assessments, and computations of the adjustment schedules necessary for effective treatment.
