Diabetes with mild nonp rtnop with macular edema, right eye

This code signifies diabetes mellitus that is a direct consequence of another underlying medical condition, not type 1 or type 2 diabetes. Specifically, it indicates the presence of mild nonproliferative diabetic retinopathy affecting the right eye, further complicated by macular edema.

Apply this code when documentation clearly states diabetes is secondary to another condition (e.g., cystic fibrosis, pancreatectomy) and the patient presents with mild nonproliferative diabetic retinopathy with macular edema in the right eye. Ensure the physician explicitly links the diabetes to the underlying condition.

• Always sequence the underlying condition causing the diabetes first, followed by this code.
• Verify laterality (right eye) and the specific severity and type of retinopathy (mild nonproliferative) and the presence of macular edema.
• Do not use this code for type 1 or type 2 diabetes; separate codes exist for those etiologies.
