CPT® Code 20690

The procedure described by CPT® Code 20690 involves the application of a uniplane external fixation system, which is a medical technique used to stabilize fractures or joint injuries. This method is particularly beneficial in cases where traditional casting may not provide adequate support or when the injury requires more precise alignment. The term "uniplane" indicates that the fixation system utilizes pins or wires that are positioned in a single plane, providing stability to the affected area. The procedure is performed unilaterally, meaning it is applied to one side of the body only. During the procedure, the patient is placed under general anesthesia to ensure comfort and immobility. A specialized drill is employed to create small holes in the affected bones, allowing for the insertion of wires or pins. These pins or wires are then passed through the skin and into the bone, connecting to an external fixation device that is secured outside the body. This external device plays a crucial role in maintaining the proper alignment of the fracture or joint injury, facilitating the healing process by allowing for controlled movement and stability. It is important to note that CPT® Code 20690 specifically refers to the uniplane system, while a different code, CPT® Code 20692, is designated for a multiplane external fixation system, which involves a more complex arrangement of pins or wires for stabilization.
