Type 2 diab with mild nonp rtnop with macular edema, l eye

This code signifies a patient diagnosed with type 2 diabetes mellitus who has developed a mild form of nonproliferative diabetic retinopathy (NPDR) affecting the left eye. Crucially, this specific retinopathy is complicated by the presence of macular edema, indicating fluid accumulation in the macula, which can impair central vision.

Use this code when documentation confirms type 2 diabetes and an ophthalmological examination reveals mild NPDR with macular edema in the left eye. This diagnosis is typically supported by funduscopic findings, optical coherence tomography (OCT) imaging demonstrating macular edema, and a confirmed diagnosis of type 2 diabetes.

• Ensure the documentation clearly specifies "mild" nonproliferative retinopathy and the presence of macular edema.
• Verify the affected eye is explicitly stated as the "left eye" to avoid laterality errors.
• Always sequence the diabetes code (E11.-) first, as it is the underlying systemic condition causing the retinopathy.
