ICD-10 Code H34.829 – Venous Engorgement, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H34.829 – Venous engorgement, unspecified eye
What it is
This code identifies venous engorgement affecting the eye when the documentation does not specify the exact eye or cause. It signals abnormal dilation or congestion of ocular veins.
Clinical signs
Findings may include visibly dilated retinal or conjunctival veins and related ocular congestion. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents venous engorgement of the eye without naming a more specific diagnosis or laterality. It is appropriate for charted eye vein congestion, vascular fullness, or similar wording when no alternate condition is stated. Check documentation if the note suggests another retinal vascular disorder.
Do not use for
Do not use this code for retinal vein occlusion, hemorrhage, or generalized conjunctival redness unless venous engorgement is explicitly documented. If a more specific eye disorder is recorded, code that condition instead.
Coding tip
Query the provider for laterality or a more specific retinal vascular diagnosis when the note is vague.
