ICD-10 Code H35.03 – Hypertensive Retinopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.03 – Hypertensive retinopathy
What it is
H35.03 identifies retinal damage caused by high blood pressure. Use it when documentation states hypertensive changes in the retina, including vascular narrowing or other pressure-related retinal findings.
Clinical signs
Findings may include arteriolar narrowing, retinal hemorrhages, cotton-wool spots, or optic disc swelling. Clinical features vary; refer to documentation for the exact severity and eye findings.
When to use this code
Use this code when the provider documents hypertensive retinopathy or retinal changes attributed to hypertension. It is appropriate for eye examinations, ophthalmology assessments, or follow-up visits documenting pressure-related retinal injury. Code the condition only when the record supports a direct hypertensive cause.
Do not use for
Do not use H35.03 for nonspecific visual complaints or retinal disease without a documented hypertensive cause. Check documentation if the note describes diabetic, vascular, or other retinal pathology instead.
Coding tip
Verify that hypertension is linked to the retinal findings in the provider’s note before assigning H35.03.
