Drug/chem diab with mild nonp rtnop with mclr edema, r eye

This code signifies diabetes mellitus caused by a drug or chemical, specifically presenting with early-stage diabetic retinopathy characterized by microaneurysms and hemorrhages, and swelling of the macula in the right eye. The retinopathy is not yet severe enough to involve new vessel growth.

Apply this code when documentation clearly states drug- or chemical-induced diabetes and mild nonproliferative diabetic retinopathy with macular edema affecting the right eye. This code is appropriate when the physician explicitly links the diabetes to a drug or chemical exposure.

• Always code the drug or chemical responsible for the diabetes as an additional diagnosis.
• Ensure the documentation specifies "mild" nonproliferative retinopathy and "macular edema" in the "right eye."
• Differentiate from other types of diabetes (e.g., Type 1, Type 2) and other stages of retinopathy.
