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

This code signifies diabetes mellitus caused by a drug or chemical, specifically presenting with moderate nonproliferative diabetic retinopathy and macular edema affecting the right eye. This indicates a specific stage of diabetic eye disease with fluid accumulation in the macula, stemming from an iatrogenic or toxic etiology.

Use this code when documentation clearly states drug or chemical-induced diabetes and specifies moderate nonproliferative diabetic retinopathy with macular edema in the right eye. This typically applies to patients whose diabetes developed as a side effect of medication or exposure to certain chemicals, and who are now experiencing this specific ocular complication.

• Always ensure the documentation explicitly links the diabetes to a drug or chemical cause.
• Verify the laterality (right eye) and the specific stage of retinopathy (moderate nonproliferative) and presence of macular edema.
• Do not use this code for type 1 or type 2 diabetes with similar retinopathy; those have different primary diabetes codes.
