Drug/chem diab with stable prolif diabetic rtnop, left eye

This code signifies diabetes mellitus caused by medication or chemical exposure, specifically presenting with stable proliferative diabetic retinopathy affecting the left eye. Proliferative retinopathy involves abnormal new blood vessel growth in the retina, and "stable" indicates no active progression or regression at the time of assessment.

Apply this code when a patient has a documented history of drug or chemical-induced diabetes and an ophthalmological examination confirms stable proliferative diabetic retinopathy in the left eye. Documentation should clearly state the etiology of the diabetes and the specific eye affected by the stable proliferative retinopathy.

• Always code the drug or chemical responsible for the diabetes as an additional diagnosis.
• Ensure documentation specifies "stable" proliferative retinopathy; otherwise, a different subcategory may be more appropriate.
• Verify laterality (left eye) is clearly documented to avoid coding errors.
