ICD-10 Code H35.21 – Other non-diabetic proliferative retinopathy, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.21 – Other non-diabetic proliferative retinopathy, right eye
What it is
H35.21 identifies proliferative retinopathy in the right eye that is not caused by diabetes. It describes abnormal retinal vessel growth or related proliferative changes documented specifically in the right eye.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may note retinal neovascularization, vitreous hemorrhage, tractional changes, or other proliferative retinal findings in the right eye.
When to use this code
Use H35.21 when the provider documents non-diabetic proliferative retinopathy affecting the right eye. It is appropriate when the condition is clearly identified as proliferative and not attributed to diabetes. If laterality is not stated, check documentation before coding.
Do not use for
Do not use this code for diabetic retinopathy or for nonproliferative retinal disease. If the record does not specify the right eye or the proliferative nature of the retinopathy, check documentation.
Coding tip
Verify both laterality and non-diabetic cause in the note before assigning H35.21.
