Type 1 diab with mild nonp rtnop with macular edema, l eye

This code signifies a diagnosis of Type 1 diabetes where the patient has developed mild nonproliferative diabetic retinopathy affecting the macula of the left eye. This indicates early-stage retinal damage due to diabetes, specifically involving the central part of the retina responsible for sharp, detailed vision, and is characterized by fluid leakage.

Use this code when documentation clearly states Type 1 diabetes and mild nonproliferative diabetic retinopathy with macular edema is present in the left eye. This is typically supported by ophthalmology examination notes, including findings from fundus photography, optical coherence tomography (OCT), or fluorescein angiography.

• Ensure the documentation specifies "Type 1" diabetes; do not use for Type 2 or unspecified diabetes.
• Verify the laterality (left eye) and the presence of macular edema, as separate codes exist for other laterality or absence of edema.
• Sequence this code after the primary diabetes diagnosis if the retinopathy is a manifestation.
