ICD-10 Code E11.339 – Type 2 diabetes mellitus with moderate nonproliferative diabetic retinopathy without macular edema (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.339 – Type 2 diabetes mellitus with moderate nonproliferative diabetic retinopathy without macular edema
What it is
This code identifies type 2 diabetes with moderate nonproliferative diabetic retinopathy, meaning diabetic damage to the retina is present but there is no macular edema. It tells you the eye complication is linked to diabetes and is not yet proliferative.
Clinical signs
Clinical features vary; refer to documentation. Standard findings may include retinal microaneurysms, hemorrhages, or hard exudates consistent with moderate nonproliferative retinopathy, with no documented macular edema.
When to use this code
Use this code when the record clearly links the patient’s type 2 diabetes to moderate nonproliferative diabetic retinopathy and explicitly states that macular edema is absent. You should rely on ophthalmology or retinal examination documentation. If the severity or edema status is unclear, check documentation before coding.
Do not use for
Do not use this code if the chart shows proliferative retinopathy, macular edema, or a different diabetic eye complication. Do not assign it when diabetic retinopathy is not documented as moderate.
Coding tip
Verify both the retinopathy severity and the absence of macular edema before assigning E11.339.
