ICD-10 Code H34.822 – Venous engorgement, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H34.822 – Venous engorgement, left eye
What it is
This code identifies venous engorgement affecting the left eye. It describes abnormal fullness or distention of ocular veins, not a specific cause or a complete diagnosis.
Clinical signs
Findings may include visibly dilated conjunctival or episcleral veins and eye redness. Clinical features vary; refer to documentation for the exact ocular findings and laterality.
When to use this code
Use H34.822 when the record specifically documents venous engorgement in the left eye. It is appropriate when the provider names this condition without a more specific underlying diagnosis. If the chart identifies another cause, code the documented condition instead.
Do not use for
Do not use this code for nonspecific eye redness, general vascular congestion, or bilateral findings unless the left eye is clearly documented. Check documentation if the record describes a different ocular disorder.
Coding tip
Verify laterality carefully; H34.822 is left eye only, and the provider’s wording should support that specificity.
