Drug/chem diab with mild nonp rtnop without mclr edema, unsp

This diagnosis code signifies diabetes mellitus that has been caused by a drug or chemical agent, specifically presenting with early-stage diabetic retinopathy. The retinopathy is characterized by microaneurysms and hemorrhages without new vessel formation, and there is no swelling of the macula, affecting an unspecified eye.

Use this code when documentation clearly states drug or chemical-induced diabetes and mild nonproliferative diabetic retinopathy is present without macular edema. This is appropriate when the specific eye affected is not documented or is unknown. Supporting documentation would include physician notes detailing the etiology of diabetes and ophthalmological findings.

• Ensure the documentation explicitly links the diabetes to a drug or chemical, not Type 1 or Type 2.
• Verify the retinopathy is specifically described as "mild nonproliferative" and "without macular edema."
• Do not use if the affected eye (left or right) is specified; instead, use the more specific laterality codes.
