CPT® Code 21820

The CPT® Code 21820 refers to the closed treatment of a sternum fracture, which is a type of injury involving the breastbone, located in the center of the chest. In this procedure, the fracture is assessed and determined to be stable and non-displaced, meaning that the bone fragments have not moved out of their normal alignment. This assessment is typically confirmed through the use of X-rays, which are reported separately to document the condition of the fracture. During the closed treatment process, no external devices such as braces or splints are applied to stabilize the fracture. Instead, the focus is on managing the patient's activity level, with recommendations for reduced physical activity to facilitate healing. This approach is generally aimed at minimizing discomfort and promoting recovery without the need for surgical intervention or invasive procedures.
