ICD-10 Code H35.033 – Hypertensive retinopathy, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.033 – Hypertensive retinopathy, bilateral
What it is
H35.033 identifies retinal damage in both eyes caused by high blood pressure. It is used when hypertension has produced documented changes in the retina.
Clinical signs
Findings may include retinal arteriolar narrowing, arteriovenous nicking, hemorrhages, cotton-wool spots, or optic disc swelling. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents hypertensive retinopathy affecting both eyes. It applies when the retinal changes are attributed to hypertension, whether noted on routine eye exam or specialist evaluation. Confirm laterality and the documented diagnosis before coding.
Do not use for
Do not use it for unspecified retinopathy, diabetic retinopathy, or eye findings without a stated hypertensive cause. Check documentation if the record does not clearly link the retinal changes to hypertension.
Coding tip
Verify that both laterality and the hypertension-related cause are documented before assigning H35.033.
