Drug/chem diab with mild nonp rtnop without mclr edema, bi

This code describes diabetes mellitus that has been caused by a drug or chemical, specifically noting the presence of mild nonproliferative diabetic retinopathy affecting both eyes. Importantly, there is no macular edema associated with the retinopathy.

Use this code when documentation clearly indicates drug or chemical-induced diabetes mellitus and an ophthalmological examination confirms mild nonproliferative diabetic retinopathy in both eyes, with no mention of macular edema. This code is appropriate when the physician explicitly links the diabetes to a specific drug or chemical exposure.

• Always verify the etiology of the diabetes (drug/chemical-induced) and the specific type and severity of retinopathy.
• Ensure documentation specifies "mild" nonproliferative retinopathy and the absence of macular edema.
• Code also the drug or chemical responsible for the diabetes, if known and documented.
