ICD-10 Code H34.8 – Other retinal vascular occlusions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H34.8 – Other retinal vascular occlusions
What it is
H34.8 identifies retinal vascular occlusions that do not fit a more specific retinal artery or vein occlusion code. It is used when the record documents an atypical or unspecified retinal vessel blockage.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include sudden visual loss, blurred vision, visual field defects, or retinal ischemic changes on eye examination.
When to use this code
Use H34.8 when the ophthalmology note clearly states another retinal vascular occlusion and does not name a more specific subtype. It may apply when the provider documents an unusual retinal vessel occlusion or a retinal vascular blockage not otherwise classified. Check documentation if the exact vessel or mechanism is unclear.
Do not use for
Do not use this code for central, branch, or other specifically named retinal artery or vein occlusions when a more specific code is available. Avoid it when the diagnosis is only suspected or not documented.
Coding tip
Code the most specific retinal occlusion documented; if the note is vague, query the provider before assigning H34.8.
