ICD-10 Code H34.11 – Central retinal artery occlusion, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H34.11 – Central retinal artery occlusion, right eye
What it is
H34.11 identifies central retinal artery occlusion affecting the right eye. It means blood flow through the main retinal artery is blocked, causing sudden loss of vision in that eye.
Clinical signs
Typical findings include sudden, painless monocular vision loss and a marked decrease in visual acuity. Funduscopic features may include retinal whitening and a cherry-red spot; clinical features vary, so refer to documentation.
When to use this code
Use H34.11 when the clinician documents central retinal artery occlusion in the right eye. Apply it for confirmed or clearly diagnosed right-sided CRAO in the chart. If the record only says retinal artery occlusion without laterality, check documentation before coding.
Do not use for
Do not use this code for left eye or bilateral retinal artery occlusion, or for branch retinal artery occlusion. If the note describes another retinal vascular disorder, choose the documented condition instead.
Coding tip
Always verify laterality in the ophthalmology or emergency note before assigning H34.11.
