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

This code signifies diabetes mellitus resulting from drug or chemical exposure, specifically presenting with moderate nonproliferative diabetic retinopathy affecting both eyes, complicated by macular edema. It indicates a significant ocular complication of drug-induced diabetes, impacting central vision.

This code is appropriate when a patient's diabetes is explicitly documented as caused by a drug or chemical, and ophthalmological examination confirms moderate nonproliferative diabetic retinopathy with macular edema in both eyes. Documentation should clearly link the diabetes to a specific drug or chemical and detail the severity and bilaterality of the retinopathy and the presence of macular edema.

• Always confirm the etiology of the diabetes is drug or chemical induced, not Type 1 or Type 2.
• Ensure documentation specifies "moderate nonproliferative" retinopathy and "macular edema" in both eyes.
• Do not use this code if the retinopathy is proliferative, mild, or severe nonproliferative, or if macular edema is absent or unilateral.
