Type 1 diab with mod nonp rtnop with macular edema, unsp

This code signifies Type 1 diabetes complicated by a moderate stage of non-proliferative diabetic retinopathy, specifically involving swelling of the macula in an unspecified eye. This indicates retinal damage due to diabetes, prior to the development of new, abnormal blood vessels, and affecting central vision.

Use this code when documentation confirms a patient has Type 1 diabetes and a diagnosis of moderate non-proliferative diabetic retinopathy with macular edema. This typically follows an ophthalmologic examination detailing the severity of retinopathy and the presence of macular swelling, without specifying laterality.

• Ensure the documentation explicitly states "moderate" non-proliferative retinopathy and the presence of macular edema.
• Confirm the diabetes type is clearly identified as Type 1.
• If laterality (right or left eye) is specified, a more specific code should be used.
