Deformity of bilateral orbits due to bone disease

This code signifies an abnormal shape or structure of both eye sockets resulting from a underlying bone pathology. This deformity can impact ocular function, vision, and facial aesthetics. It is distinct from deformities caused by trauma or congenital anomalies.

Apply this code when documentation explicitly states bilateral orbital deformity secondary to a systemic or localized bone disease, such as fibrous dysplasia, Paget's disease, or osteopetrosis. Supporting documentation should include imaging reports (e.g., CT, MRI) confirming the bone involvement and orbital malformation.

• Ensure the documentation specifies bilateral involvement; unilateral deformities would require a different code.
• Do not use this code for orbital deformities due to trauma, congenital conditions, or neoplastic processes.
• Always code the underlying bone disease first, as it is the etiology of the orbital deformity.
