ICD-10 Code H35.20 – Other non-diabetic proliferative retinopathy, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.20 – Other non-diabetic proliferative retinopathy, unspecified eye
What it is
Use this code for proliferative retinopathy not caused by diabetes when the affected eye is not specified. It indicates abnormal retinal blood vessel growth or related proliferative changes, with the cause documented as non-diabetic.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include retinal neovascularization, hemorrhage, or traction-related changes on eye examination, but you should only code what is clearly documented.
When to use this code
Use H35.20 when the provider documents other proliferative retinopathy and does not identify diabetes as the cause. It also applies when the record names the condition but does not specify right or left eye. If the note identifies a specific eye or underlying cause, code that information instead.
Do not use for
Do not use this code for diabetic proliferative retinopathy, because those cases belong in the diabetes-related retinopathy codes. Also avoid it when the documentation names a different retinal disorder or a specific eye that is coded elsewhere.
Coding tip
Check the ophthalmology note for laterality and the cause of retinopathy before assigning H35.20.
