Drug/chem diab with prolif diab rtnop w/o mclr edema, unsp

This code signifies diabetes mellitus caused by a drug or chemical, specifically complicated by the presence of proliferative diabetic retinopathy. It indicates that macular edema is absent and the affected eye is not specified. This condition involves abnormal new blood vessel growth in the retina due to the drug-induced diabetes.

Use this code when documentation clearly states drug or chemical-induced diabetes mellitus with proliferative diabetic retinopathy, explicitly noting the absence of macular edema. This diagnosis requires a confirmed causal link between medication/chemical exposure and the onset of diabetes. Supporting documentation includes physician notes detailing the etiology of diabetes, ophthalmology reports confirming proliferative retinopathy, and absence of macular edema.

• Always sequence the drug or chemical causing the diabetes first, if known and if it's an adverse effect or poisoning.
• Ensure documentation specifies "proliferative" retinopathy and explicitly states "without macular edema."
• Do not use this code for Type 1, Type 2, or other specified types of diabetes unless a drug/chemical is the direct cause.
