Oth diab with mild nonp rtnop without macular edema, l eye

This code signifies a patient diagnosed with a form of diabetes mellitus other than type 1 or type 2, who also presents with early-stage diabetic retinopathy in their left eye. This retinopathy is characterized by microaneurysms, hemorrhages, or hard exudates, but without new vessel formation or swelling of the macula.

Use this code when documentation confirms a diagnosis of "other specified diabetes mellitus" (e.g., secondary diabetes due to cystic fibrosis or pancreatectomy) and ophthalmological findings indicate mild nonproliferative diabetic retinopathy affecting only the left eye, with no evidence of macular edema. The physician's notes should clearly specify the type of diabetes and the laterality and severity of the retinopathy.

• Always code the underlying diabetes type first, if known and applicable (e.g., E08.-, E09.-, E10.-, E11.-).
• Ensure the documentation explicitly states "mild nonproliferative" and "without macular edema" for the left eye.
• Do not use this code if the retinopathy is proliferative, severe, or involves macular edema, or if both eyes are affected.
