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

This code signifies diabetes mellitus that has been induced by a drug or chemical, specifically presenting with mild nonproliferative diabetic retinopathy affecting both eyes, and complicated by macular edema. This form of diabetes is distinct from Type 1 or Type 2 and is directly attributable to an external substance.

Apply this code when documentation clearly indicates drug or chemical-induced diabetes mellitus. The patient must also have mild nonproliferative diabetic retinopathy with macular edema, confirmed to be present in both eyes. This code is appropriate when the causal link between a medication or chemical exposure and the onset of diabetes is established.

• Always sequence the drug/chemical code (T36-T65) as a secondary diagnosis to identify the specific causative agent.
• Ensure documentation specifies "mild nonproliferative" retinopathy and "macular edema" in both eyes; otherwise, a less specific code may be required.
• Differentiate from other diabetes types (E10, E11, E13) where the etiology is not drug or chemical induced.
