Diabetes with mild nonp rtnop without macular edema, r eye

This code signifies diabetes mellitus that is a direct consequence of another underlying medical condition, rather than type 1 or type 2 diabetes. Specifically, it indicates the presence of early-stage diabetic retinopathy in the right eye, characterized by microaneurysms or hemorrhages without swelling of the macula, and the retinopathy is not severe enough to involve new blood vessel growth.

Use this code when documentation clearly links a patient's diabetes to a specific underlying condition (e.g., cystic fibrosis, pancreatitis, drug-induced diabetes). The patient must also have mild, non-proliferative diabetic retinopathy affecting only the right eye, with no mention of macular edema. Supported by ophthalmology reports detailing the specific findings in the right eye and the physician's assessment of the diabetes etiology.

• Always sequence the underlying condition code first, followed by this diabetes code.
• Distinguish carefully between "due to underlying condition" and other diabetes types (E09, E10, E11, E13).
• Ensure documentation specifies "mild" nonproliferative retinopathy and "right eye" without "macular edema" to avoid more severe or bilateral retinopathy codes.
