Atrophy of globe, bilateral

This code signifies a degenerative condition affecting both eyes, characterized by the progressive shrinking and wasting away of the eyeball. This atrophy leads to a reduction in the globe's size and often results in severe vision impairment or blindness.

Apply this code when documentation explicitly states bilateral atrophy of the globe. This diagnosis is typically made based on clinical examination, imaging studies (e.g., ultrasound, CT scan), and a history of underlying ocular trauma, inflammation, or disease leading to the degeneration.

• Ensure documentation specifies bilateral involvement; unilateral atrophy would require a different code.
• Always code any underlying cause of the globe atrophy, if known and documented, as a primary or secondary diagnosis.
• Differentiate from microphthalmos (congenitally small eye) or phthisis bulbi (end-stage atrophy with disorganization).
