ICD-10 Code H34.823 – Venous engorgement, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H34.823 – Venous engorgement, bilateral
What it is
This code identifies venous engorgement in both eyes, meaning the retinal veins appear abnormally dilated or congested. Use it when documentation specifically states bilateral venous engorgement.
Clinical signs
Clinical features vary; refer to documentation. Eye examination may note prominent, enlarged retinal veins in both eyes, sometimes with other retinal vascular changes.
When to use this code
Use H34.823 when the provider documents bilateral venous engorgement as the diagnosed finding. It is appropriate for ophthalmology or retinal assessments where the record clearly names both eyes. If the note only says venous congestion or vascular changes without laterality, check documentation.
Do not use for
Do not use this code for unilateral venous engorgement or for nonspecific retinal vein disorders. If the chart describes a different retinal vascular diagnosis, code that condition instead.
Coding tip
Verify laterality in the assessment or impression, because this code is specific to bilateral involvement.
