Drug/chem diab with mod nonp rtnop without mclr edema, r eye

This code describes diabetes mellitus that has been caused by a drug or chemical, specifically presenting with moderate nonproliferative diabetic retinopathy in the right eye. Importantly, there is no macular edema associated with this retinopathy. This condition signifies a moderate level of retinal damage due to the drug-induced diabetes.

Use this code when documentation clearly indicates a patient's diabetes is iatrogenic (drug or chemical induced) and an ophthalmological examination confirms moderate nonproliferative diabetic retinopathy affecting only the right eye, without any mention of macular edema. This code requires a definitive link between a medication/chemical exposure and the onset of diabetes.

• Always sequence the drug or chemical responsible for the diabetes as an additional diagnosis.
• Confirm laterality (right eye) and the absence of macular edema are explicitly documented.
• Distinguish carefully from type 1 or type 2 diabetes with similar retinopathy; the etiology must be drug/chemical induced.
