Atrophy of globe, left eye

This code signifies a degenerative condition affecting the left eye, characterized by a reduction in the size and volume of the eyeball. This atrophy often results from severe trauma, chronic inflammation, or end-stage ocular diseases, leading to significant vision loss or blindness in the affected eye.

Apply this code when documentation explicitly states "atrophy of globe, left eye" or describes a shrunken, non-functional left eyeball. This diagnosis is typically made based on clinical examination, imaging studies (e.g., ultrasound, CT scan), and a history of severe ocular insult.

• Ensure laterality is clearly documented as "left eye" to support this specific code.
• Do not confuse with phthisis bulbi (H44.51-), which is a more severe, end-stage atrophy with disorganization of intraocular contents.
• Code any underlying cause of the globe atrophy (e.g., severe trauma, glaucoma) as an additional diagnosis, if known and still active.
