ICD-10 Code H34.213 – Partial retinal artery occlusion, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H34.213 – Partial retinal artery occlusion, bilateral
What it is
H34.213 identifies a partial blockage of the retinal arteries in both eyes. Use it when documentation states bilateral retinal artery occlusion that is incomplete or partial rather than total.
Clinical signs
Clinical features may include sudden visual disturbance, field loss, or reduced vision in both eyes. Findings depend on exam and imaging; clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents partial retinal artery occlusion affecting both eyes, including bilateral ischemic retinal findings. It may also fit when the record clearly states bilateral branch or partial arterial obstruction of the retina. Check documentation if the laterality or completeness is unclear.
Do not use for
Do not use H34.213 for central retinal artery occlusion, unilateral disease, or retinal vein occlusion. If the note does not confirm bilateral partial involvement, choose a more specific or different code.
Coding tip
Verify both laterality and whether the occlusion is partial before assigning H34.213.
