CPT® Code 21406

The CPT® Code 21406 refers to the open treatment of a fracture of the orbit, specifically excluding blowout fractures, and is performed without the use of an implant. This procedure is designed to restore the natural shape of the orbit, which is the bony cavity that houses the eye. In cases of orbital fractures, the integrity of the orbit can be compromised, leading to potential complications such as misalignment of the eye, double vision, or damage to surrounding structures. The open repair technique involves making an incision to access the fractured area directly, allowing for precise manipulation and correction of the fracture. The procedure may also include the use of a temporary tarsorrhaphy, which is a technique to protect the cornea by suturing the eyelids partially closed. This is particularly important during the initial stages of the procedure to prevent exposure and injury to the eye. The surgical approach requires careful dissection to preserve the surrounding tissues and nerves, ensuring that the repair is both effective and minimizes the risk of complications. Overall, the goal of this procedure is to restore the anatomical and functional integrity of the orbit, thereby improving the patient's visual and cosmetic outcomes.
