Drug/chem diab with mod nonp rtnop without mclr edema, l eye

This code signifies diabetes mellitus that has been caused by a drug or chemical, specifically presenting with moderate nonproliferative diabetic retinopathy in the left eye, without any associated macular edema. This form of diabetes is distinct from Type 1 or Type 2 as its etiology is iatrogenic or exposure-related. The retinopathy indicates damage to the small blood vessels of the retina due to the diabetic condition.

Use this code when documentation clearly states drug or chemical-induced diabetes mellitus and specifies moderate nonproliferative diabetic retinopathy affecting the left eye, with no mention of macular edema. This code is appropriate when the physician explicitly links the diabetes to a medication or chemical exposure. Supporting documentation would include a definitive diagnosis of drug/chemical-induced diabetes and ophthalmological findings detailing the specific retinopathy stage and laterality.

• Always ensure the documentation specifies "drug or chemical induced" diabetes, as this is a key differentiator from other diabetes types.
• Verify the laterality (left eye) and the absence of macular edema, as these details are crucial for accurate code selection.
• Sequence this code after the primary diagnosis if the drug/chemical-induced diabetes is a manifestation of another underlying condition, or as the primary diagnosis if it is the reason for the encounter.
