ICD-10 Code E08.341 – Diabetes mellitus due to underlying condition with severe nonproliferative diabetic retinopathy with macular edema (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E08.341 – Diabetes mellitus due to underlying condition with severe nonproliferative diabetic retinopathy with macular edema
What it is
This code identifies diabetes caused by another underlying condition, with severe nonproliferative diabetic retinopathy and macular edema in an eye. It tells you the eye disease is a complication of the diabetes.
Clinical signs
Clinical features vary; refer to documentation. Common findings include retinal hemorrhages, venous changes, and macular swelling documented by an eye specialist or retinal imaging.
When to use this code
Use this code when the record states diabetes due to an underlying condition and documents severe nonproliferative diabetic retinopathy with macular edema. Apply it when the eye complication is clearly linked to the diabetes and the severity is specified.
Choose the correct laterality and any additional diabetes-related codes if the chart supports them. Check documentation when the underlying condition is named but the eye findings are not fully described.
Do not use for
Do not use this code for diabetic retinopathy without macular edema, or when the record only says retinopathy unspecified. Do not use it if diabetes is not documented as due to an underlying condition.
Coding tip
Verify both the diabetes type and the exact retinal severity before assigning E08.341.
