CPT® Code 21408

The CPT® Code 21408 refers to the open treatment of a fracture of the orbit, excluding blowout fractures, which involves the use of bone grafting. This procedure is essential for restoring the orbit to its natural anatomical shape and function after a fracture has occurred. The orbit is the bony cavity that houses the eye, and fractures in this area can lead to significant complications, including misalignment of the eye, double vision, and cosmetic deformities. The procedure begins with a thorough evaluation of the natural skin creases around the eye, followed by careful marking of incision lines to minimize scarring. A temporary tarsorrhaphy may be performed to protect the cornea by suturing the eyelids together, which helps to shield the eye during the surgical intervention. The surgical approach involves making an incision to access the underlying muscles and tissues, allowing for the identification and repair of the fractured bone. Bone grafting is a critical component of this procedure, as it involves harvesting bone from another site in the body and shaping it to fit the defect created by the fracture. This graft not only restores the structural integrity of the orbit but also prevents the soft tissues from prolapsing into the fracture site, thereby ensuring proper healing and function of the eye. Overall, this procedure is complex and requires a high level of surgical skill to achieve optimal outcomes for the patient.
