ICD-10 Code H35.032 – Hypertensive retinopathy, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.032 – Hypertensive retinopathy, left eye
What it is
This code identifies hypertensive damage to the retina in the left eye. It is used when the record specifies retinopathy caused by hypertension and the affected eye is the left eye.
Clinical signs
Findings may include retinal vascular changes, such as narrowing or arteriolar sclerosis, with possible retinal hemorrhages, exudates, or optic disc changes. Clinical features vary; refer to documentation.
When to use this code
Use H35.032 when the provider documents hypertensive retinopathy limited to the left eye. You should code it when the note clearly links the retinal findings to hypertension and laterality is stated. If the eye is not specified, check documentation.
Do not use for
Do not use this code for retinopathy from diabetes or other nonhypertensive causes. Do not assign it when the chart only mentions hypertension without retinal involvement.
Coding tip
Confirm both the hypertensive cause and left-eye laterality before coding.
