ICD-10 Code H35.22 – Other non-diabetic proliferative retinopathy, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.22 – Other non-diabetic proliferative retinopathy, left eye
What it is
H35.22 identifies proliferative retinopathy in the left eye that is not caused by diabetes. Use it when documentation specifies abnormal retinal new vessel growth or related proliferative change affecting only the left eye.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include retinal neovascularization, vitreous or preretinal hemorrhage, and ischemic retinal changes on eye examination or imaging.
When to use this code
Use this code when the provider documents proliferative retinopathy in the left eye and states it is non-diabetic. It may apply after ophthalmology evaluation, retinal imaging, or follow-up for known retinal vascular disease. If the note does not clearly identify the cause, check documentation.
Do not use for
Do not use it for diabetic retinopathy or for proliferative retinopathy affecting the right eye or both eyes. If the record only says “retinopathy” without proliferative change or laterality, check documentation.
Coding tip
Confirm both laterality and non-diabetic etiology in the provider note before assigning H35.22.
