Drug/chem diab with severe nonp rtnop w/o mclr edema, r eye

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

Use this code when documentation clearly states drug or chemical-induced diabetes and severe nonproliferative diabetic retinopathy affecting the right eye, explicitly noting the absence of macular edema. This diagnosis is supported by ophthalmological examination findings detailing the severity and laterality of the retinopathy.

• Always confirm the etiology of the diabetes as drug or chemical-induced, not Type 1 or Type 2.
• Verify the specific severity of the retinopathy (severe nonproliferative) and the absence of macular edema.
• Ensure laterality (right eye) is explicitly documented; codes exist for left eye, bilateral, and unspecified.
