Drug/chem diab with prolif diab rtnop w/o mclr edema, l eye

This diagnosis code identifies diabetes mellitus that has been caused by a drug or chemical agent, specifically presenting with proliferative diabetic retinopathy in the left eye. Importantly, there is no associated macular edema in the left eye. This indicates severe retinal damage with new, abnormal blood vessel growth due to the drug-induced diabetes.

This code is appropriate when a patient's diabetes is directly attributed to a medication or chemical exposure, and ophthalmological examination confirms proliferative diabetic retinopathy affecting only the left eye, without evidence of macular edema. Documentation should clearly state the drug or chemical as the etiology of the diabetes and specify the type and laterality of the retinopathy.

• Ensure documentation explicitly links the diabetes to a drug or chemical cause.
• Verify the laterality (left eye) and the absence of macular edema in the ophthalmology report.
• Distinguish from other types of diabetes (e.g., Type 1, Type 2) and other forms of diabetic retinopathy.
