Drug/chem diab with mod nonp rtnop without macular edema, bi

This code signifies diabetes mellitus that has been induced by a drug or chemical agent, specifically presenting with moderate nonproliferative diabetic retinopathy affecting both eyes. Importantly, there is no associated macular edema in either eye. This condition reflects a specific stage of diabetic eye disease stemming from an exogenous cause.

Apply this code when documentation clearly states drug or chemical-induced diabetes and bilateral moderate nonproliferative diabetic retinopathy without macular edema. This is appropriate for patients whose diabetes onset is directly attributable to medication or chemical exposure, and who exhibit this specific level of retinal damage. Supporting documentation includes physician notes detailing the etiology of diabetes and ophthalmological reports confirming the retinopathy stage and absence of macular edema.

• Always verify the specific etiology of the diabetes (drug/chemical-induced) as opposed to type 1, type 2, or other specified types.
• Ensure the retinopathy is explicitly documented as "moderate nonproliferative" and "without macular edema" for both eyes.
• Do not use this code if the retinopathy is proliferative, mild, severe, or if macular edema is present, even unilaterally.
