Drug/chem diab with mod nonp rtnop with macular edema, l eye

This code signifies diabetes mellitus resulting from drug or chemical exposure, specifically presenting with moderate nonproliferative diabetic retinopathy affecting the macula of the left eye. This indicates a stage of diabetic eye disease where microaneurysms, hemorrhages, and hard exudates are present, and the central vision is impacted by fluid accumulation.

Apply this code when documentation clearly states drug or chemical-induced diabetes and specifies moderate nonproliferative diabetic retinopathy with macular edema in the left eye. This is typically supported by ophthalmological examination findings, including fundus photography, optical coherence tomography (OCT), and a history of medication or chemical exposure linked to diabetes onset.

• Always confirm the laterality (left eye) and the specific stage of retinopathy (moderate nonproliferative) and presence of macular edema.
• Ensure the documentation explicitly links the diabetes to drug or chemical induction, rather than type 1 or type 2.
• Sequence this code after the primary code for the drug or chemical causing the diabetes, if applicable, to fully describe the etiology.
