ICD-10 Code H35.031 – Hypertensive retinopathy, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.031 – Hypertensive retinopathy, right eye
What it is
This code identifies hypertensive retinal changes limited to the right eye. It is used when high blood pressure has caused damage or vascular changes seen in that eye.
Clinical signs
Findings may include retinal arteriolar narrowing, hemorrhages, exudates, cotton-wool spots, or optic disc swelling. Clinical features vary; refer to documentation.
When to use this code
Use H35.031 when the provider documents hypertensive retinopathy in the right eye, with or without laterality-specific ophthalmic findings. Code it when the retinal changes are attributed to hypertension and the right eye is specified. If the note only says “hypertensive retinopathy” without eye laterality, check documentation.
Do not use for
Do not use this code for hypertensive retinopathy of the left eye, both eyes, or unspecified eye. Also avoid it when retinal changes are due to another cause, such as diabetes or vascular occlusion.
Coding tip
Always verify laterality in the ophthalmology note before assigning H35.031.
