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

This code signifies a diagnosis of type 2 diabetes mellitus complicated by severe nonproliferative diabetic retinopathy affecting the left eye, specifically with the presence of macular edema. This represents a significant microvascular complication of diabetes impacting vision.

This code is appropriate when a patient with type 2 diabetes is documented with severe nonproliferative diabetic retinopathy and concurrent macular edema in their left eye. Documentation should clearly specify the type of diabetes, the severity of retinopathy, and the laterality and presence of macular edema.

• Always confirm the type of diabetes (type 1 vs. type 2) and the specific eye affected.
• Ensure documentation differentiates between nonproliferative and proliferative retinopathy.
• Look for explicit mention of "macular edema" as opposed to other types of diabetic macular pathology.
