Type 2 diab with severe nonp rtnop without mclr edema, r eye

This code identifies a patient diagnosed with type 2 diabetes who has developed severe nonproliferative diabetic retinopathy (NPDR) in their right eye. This stage of retinopathy is characterized by significant microvascular damage, such as widespread intraretinal hemorrhages and venous beading, but without the presence of new vessel growth or macular edema.

Use this code when documentation clearly states type 2 diabetes and severe nonproliferative diabetic retinopathy affecting the right eye, explicitly noting the absence of macular edema. This is typically found in ophthalmology reports, diabetic eye exam findings, or physician progress notes.

• Ensure the documentation specifies "severe" nonproliferative retinopathy and the affected eye (right).
• Verify the absence of macular edema; if present, a different code from the E11.34- series would be appropriate.
• Always code the underlying diabetes (E11.-) first, followed by the retinopathy manifestation.
