ICD-10 Code H35.23 – Other non-diabetic proliferative retinopathy, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.23 – Other non-diabetic proliferative retinopathy, bilateral
What it is
H35.23 identifies proliferative retinopathy affecting both eyes that is not due to diabetes. It describes abnormal retinal blood vessel growth or related proliferative changes documented as bilateral and non-diabetic.
Clinical signs
Clinical features vary; refer to documentation. You may see retinal neovascularization, hemorrhage, fibrosis, or tractional changes on eye exam or imaging, with findings recorded in both eyes.
When to use this code
Use H35.23 when the provider documents bilateral proliferative retinopathy and specifically states it is not diabetic. It fits cases where the retinal disease is present in both eyes and the record supports a proliferative process. If the cause is unclear, check documentation before coding.
Do not use for
Do not use this code for diabetic retinopathy or for proliferative disease limited to one eye. If the record does not clearly support bilateral, non-diabetic involvement, choose a different code or check documentation.
Coding tip
Confirm both the non-diabetic cause and bilateral laterality in the provider note before assigning H35.23.
