Deformity of left orbit due to trauma or surgery

This code signifies an abnormal shape or structure of the left eye socket resulting from a previous injury or surgical intervention. This deformity can affect the position and function of the eyeball and surrounding structures.

Apply this code when documentation clearly indicates a structural alteration of the left orbit directly attributable to a past traumatic event (e.g., fracture) or a prior surgical procedure involving the orbit. The patient's history must explicitly link the deformity to one of these etiologies.

• Ensure the documentation specifies "left" orbit; laterality is crucial.
• Distinguish from congenital orbital deformities, which have different codes.
• Verify the etiology is explicitly stated as "trauma" or "surgery" and not an unspecified cause.
