ICD-10 Code H34.219 – Partial Retinal Artery Occlusion, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H34.219 – Partial retinal artery occlusion, unspecified eye
What it is
H34.219 identifies a partial blockage of a retinal artery in an unspecified eye. It means blood flow to part of the retina is reduced, but the record does not specify right or left eye.
Clinical signs
Findings may include sudden visual disturbance, blurred vision, or a partial visual field defect. Clinical features vary; refer to documentation and ophthalmic examination notes.
When to use this code
Use this code when the provider documents partial retinal artery occlusion and does not identify the affected eye. It is appropriate for confirmed retinal artery obstruction involving only part of the retinal circulation. If the note later specifies laterality, code that more specific option instead.
Do not use for
Do not use this code for central retinal artery occlusion, branch retinal artery occlusion, or retinal vein occlusion. Check documentation if the note only describes transient visual loss without confirmed arterial occlusion.
Coding tip
Verify laterality and whether the occlusion is partial before assigning H34.219.
