ICD-10 Code E13.341 – Other specified diabetes mellitus with severe nonproliferative diabetic retinopathy with macular edema (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.341 – Other specified diabetes mellitus with severe nonproliferative diabetic retinopathy with macular edema
What it is
This code identifies diabetes mellitus in the “other specified” category with severe nonproliferative diabetic retinopathy and macular edema. It indicates significant diabetic eye disease affecting the retina and central vision area.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include severe nonproliferative retinal changes and documented macular edema on eye examination or ophthalmology assessment.
When to use this code
Use this code when the record clearly states other specified diabetes mellitus with severe nonproliferative diabetic retinopathy and macular edema. You should code it when the diabetes type is documented in the “other specified” category and the eye complication is linked to that diabetes.
Confirm that both the retinopathy severity and macular edema are documented. If the note does not specify the diabetes category or the eye complication, check documentation before assigning the code.
Do not use for
Do not use this code for proliferative retinopathy, mild or moderate nonproliferative retinopathy, or diabetic eye disease without macular edema. Check documentation if the diabetes type is not clearly “other specified.”
Coding tip
Assign the code only when the provider documents both severe nonproliferative retinopathy and macular edema with the correct diabetes category.
