Type 1 diab with mod nonp rtnop without macular edema, r eye

This code signifies a patient diagnosed with Type 1 diabetes who has developed moderate nonproliferative diabetic retinopathy in their right eye. Importantly, there is no evidence of macular edema affecting the central vision in this eye. This stage of retinopathy involves microaneurysms, hemorrhages, and cotton wool spots, but not new vessel growth.

Use this code when documentation confirms Type 1 diabetes and an ophthalmological examination reveals moderate nonproliferative diabetic retinopathy specifically in the right eye, without any mention of macular edema. This code is appropriate when the physician explicitly states "moderate" and "nonproliferative" and specifies the "right eye" and "no macular edema."

• Ensure the documentation clearly specifies "moderate" nonproliferative retinopathy; differentiate from mild or severe.
• Verify laterality (right eye) is explicitly stated; do not assume if not documented.
• Confirm the absence of macular edema; if present, a different code from the E10.33 category would be required.
