ICD-10 Code E11.32 – Type 2 diabetes mellitus with mild nonproliferative diabetic retinopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.32 – Type 2 diabetes mellitus with mild nonproliferative diabetic retinopathy
What it is
This code identifies type 2 diabetes with mild nonproliferative changes in the retina. It means diabetes has caused early diabetic eye disease, but not the more advanced proliferative form.
Clinical signs
Findings usually include retinal microaneurysms and small hemorrhages on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use E11.32 when the provider documents type 2 diabetes and mild nonproliferative diabetic retinopathy. It may appear in ophthalmology, endocrinology, or primary care records. Code it when the retinopathy is linked to diabetes and the severity is stated.
Do not use for
Do not use this code for diabetic retinopathy that is unspecified, proliferative, or due to another diabetes type. Check documentation if the eye findings are not clearly tied to type 2 diabetes.
Coding tip
Confirm both the diabetes type and the retinopathy severity before coding.
