Diabetes with mild nonp rtnop with macular edema, unsp

This code describes a form of diabetes mellitus that develops as a consequence of another underlying medical condition, rather than being an autoimmune (Type 1) or insulin resistance-related (Type 2) diabetes. Specifically, it indicates the presence of mild nonproliferative diabetic retinopathy, characterized by microaneurysms and hemorrhages without new vessel formation, complicated by macular edema, affecting an unspecified eye.

Use this code when documentation clearly states diabetes is secondary to another condition (e.g., cystic fibrosis, pancreatitis, hemochromatosis) and mild nonproliferative diabetic retinopathy with macular edema is present. The physician's notes must specify the underlying condition causing the diabetes and the specific eye involvement for the retinopathy and macular edema.

• Always sequence the underlying condition causing the diabetes first, followed by this diabetes code.
• Ensure documentation specifies "mild nonproliferative" retinopathy and the presence of "macular edema."
• If the specific eye (right or left) is documented, use the more specific code (E08.3211 or E08.3212) instead of this unspecified eye code.
