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

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

Apply this code when documentation clearly indicates drug or chemical-induced diabetes with evidence of mild nonproliferative diabetic retinopathy and macular edema. This diagnosis typically arises from medication side effects or exposure to certain toxins, and ophthalmic examination confirms the specific retinopathy and macular involvement.

• Always sequence the drug or chemical causing the diabetes as an additional diagnosis.
• Ensure documentation specifies "mild" nonproliferative retinopathy and the presence of macular edema.
• Do not use if the diabetes is type 1, type 2, or gestational; this code is exclusively for drug/chemical induced diabetes.
