Diab with prolif diabetic rtnop without macular edema, bi

This code signifies diabetes mellitus that has developed as a consequence of another underlying medical condition, rather than being Type 1 or Type 2 diabetes. The patient presents with proliferative diabetic retinopathy affecting both eyes, characterized by the growth of new, abnormal blood vessels on the retina, but without any swelling of the macula.

This code is appropriate when documentation clearly links diabetes to a specific underlying cause (e.g., pancreatitis, cystic fibrosis, drug-induced). It should be used when an ophthalmological exam confirms bilateral proliferative diabetic retinopathy without evidence of macular edema. The underlying condition causing the diabetes must also be coded.

• Always sequence the underlying condition first, followed by this code for the diabetes manifestation.
• Ensure documentation specifies "proliferative" retinopathy and explicitly states "without macular edema" for both eyes.
• Distinguish carefully from nonproliferative diabetic retinopathy and cases with macular edema, which have different codes.
