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

This diagnosis code signifies diabetes mellitus that has been caused by a drug or chemical agent, specifically presenting with proliferative diabetic retinopathy in the right eye. Importantly, there is no associated macular edema in this particular manifestation.

Apply this code when documentation clearly states drug or chemical-induced diabetes and specifies proliferative diabetic retinopathy affecting the right eye, without any mention of macular edema. This is typically found in ophthalmology reports or endocrinology notes detailing the etiology of the diabetes and the specific retinal complications.

• Ensure the documentation explicitly links the diabetes to a drug or chemical cause, not type 1 or type 2.
• Verify laterality (right eye) and the absence of macular edema are clearly stated.
• Do not use this code if the retinopathy is nonproliferative or if macular edema is present, as separate codes exist for those conditions.
