Diab with mild nonp rtnop without macular edema, left eye

This code signifies a patient diagnosed with diabetes mellitus that is secondary to another underlying medical condition, not type 1 or type 2 diabetes. The patient exhibits mild nonproliferative diabetic retinopathy affecting the left eye, specifically without any associated macular edema.

Apply this code when documentation clearly states diabetes due to an underlying condition (e.g., cystic fibrosis, pancreatectomy) and identifies mild nonproliferative retinopathy in the left eye, explicitly noting the absence of macular edema. This code requires a definitive diagnosis of the underlying condition causing the diabetes.

• Always sequence the underlying condition causing the diabetes first, followed by this code.
• Confirm laterality (left eye) and the absence of macular edema are explicitly documented.
• Differentiate from codes for type 1 or type 2 diabetes with retinopathy; this code is specifically for secondary diabetes.
