Oth diab with severe nonp rtnop without macular edema, r eye

This code signifies a diagnosis of other specified diabetes mellitus complicated by severe nonproliferative diabetic retinopathy affecting the right eye, specifically without any associated macular edema. This represents a significant stage of diabetic eye disease where microaneurysms, hemorrhages, and venous beading are present, but new blood vessel growth has not yet occurred, and the macula remains unaffected by swelling.

Use this code when documentation clearly states "other specified diabetes mellitus" as the underlying diabetic condition, and the ophthalmologist or optometrist has diagnosed severe nonproliferative diabetic retinopathy in the patient's right eye, explicitly noting the absence of macular edema. This code is appropriate when the patient's diabetes is not type 1, type 2, or drug/chemical induced.

• Always confirm the specific type of diabetes mellitus documented, as this code is for "other specified" types.
• Ensure the documentation specifies "severe nonproliferative" retinopathy and explicitly states "without macular edema" for the right eye.
• Laterality is crucial; verify the affected eye (right, left, or bilateral) to select the most accurate code.
