Drug/chem diab with severe nonp rtnop with macular edema, bi

This code signifies diabetes mellitus caused by medication or chemical exposure, specifically when the patient presents with severe nonproliferative diabetic retinopathy affecting both eyes, and also has macular edema. This represents a significant ocular complication of drug-induced diabetes, indicating advanced retinal damage.

Apply this code when documentation clearly states a diagnosis of diabetes mellitus induced by a drug or chemical, alongside bilateral severe nonproliferative diabetic retinopathy and confirmed macular edema. Physician notes should explicitly link the diabetes to a specific drug or chemical and detail the severity and bilaterality of the retinopathy and the presence of macular edema.

• Ensure documentation specifies "severe" nonproliferative retinopathy; mild or moderate forms require different codes.
• Verify the laterality is explicitly documented as "bilateral" for both the retinopathy and macular edema.
• Confirm the etiology of the diabetes is clearly stated as drug or chemical-induced, not Type 1, Type 2, or other specified types.
