CPT® Code 21395

The CPT® Code 21395 refers to the open treatment of an orbital floor blowout fracture using a periorbital approach, which includes the process of obtaining a bone graft. This procedure is essential for addressing an orbital floor fracture, a type of injury that often occurs due to mid-facial trauma. Such fractures can lead to significant complications, including entrapment of the extraocular muscles, which may impair eye movement, as well as aesthetic deformities of the face. The surgical intervention aims to restore both the anatomical integrity and functional capabilities of the eye and surrounding structures. During the procedure, an incision is made along the lower eyelid, allowing access to the orbital area. The surgical team carefully dissects the tissue to reach the orbital rim, where the fracture is addressed. An autogenous bone graft, which is harvested from a donor site such as the maxillary wall, calvaria, iliac crest, rib, or fibula, is then shaped and inserted to fill the defect in the orbital floor. This meticulous approach ensures that the eye's position and function are preserved, while also addressing any cosmetic concerns resulting from the fracture.
