ICD-10 Code H35.011 – Changes in retinal vascular appearance, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.011 – Changes in retinal vascular appearance, right eye
What it is
This code identifies abnormal retinal blood vessel appearance in the right eye. It is used when the record describes vascular changes in the retina without a more specific diagnosis.
Clinical signs
Findings may include visible retinal vessel narrowing, tortuosity, sheathing, or other vascular irregularity on eye exam. Clinical features vary; refer to documentation.
When to use this code
Use H35.011 when the provider documents changes in retinal vascular appearance limited to the right eye and no more specific retinal disorder is stated. It may fit ophthalmology notes describing incidental or examined vascular abnormalities. Code the documented laterality exactly.
Do not use for
Do not use this code for generalized retinal disease, diabetic retinopathy, or vascular changes in the left eye or both eyes. Check documentation if the note names a different retinal condition.
Coding tip
Verify laterality and whether a more specific retinal diagnosis is documented before assigning H35.011.
