CPT® Code 21400

The CPT® Code 21400 refers to the closed treatment of a fracture of the orbit, specifically excluding blowout fractures. This procedure is characterized by the absence of manipulation, meaning that the fractured bone fragments do not require repositioning. In cases of a nondisplaced fracture of the orbit, the treatment involves a thorough evaluation of the fracture site, which is confirmed through radiographic imaging. The primary goal of this procedure is to ensure that the integrity of the neurovascular structures surrounding the orbit is maintained, which is assessed through a neurovascular examination. This examination checks for any potential damage to the nerves and blood vessels in the area of the injury. Unlike CPT® Code 21401, which involves the manipulation of displaced fracture fragments, CPT® Code 21400 is utilized when the fracture is stable and does not necessitate any corrective measures to restore anatomical alignment. The closed treatment approach is less invasive and focuses on monitoring the healing process without the need for surgical intervention to reposition the bones.
