ICD-10 Code H35.431 – Paving stone degeneration of retina, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.431 – Paving stone degeneration of retina, right eye
What it is
H35.431 identifies paving stone degeneration in the right retina. This is a peripheral retinal degeneration seen on eye examination, usually documented as an incidental finding.
Clinical signs
Findings are typically described as discrete, pale, atrophic retinal lesions in the peripheral fundus. Clinical features vary; refer to documentation.
When to use this code
Use H35.431 when the provider documents paving stone degeneration specifically in the right eye. It may appear during a routine dilated retinal exam or as a noted retinal finding without active treatment. Code the documented eye laterality exactly as recorded.
Do not use for
Do not use this code for unspecified eye or bilateral retinal degeneration unless the record supports that wording. Do not assign it for other retinal disorders, such as tears, detachment, or diabetic retinopathy.
Coding tip
Confirm laterality in the ophthalmology note before coding, because H35.431 is right-eye specific.
