Diabetes with severe nonp rtnop without macular edema, r eye

This code signifies diabetes that has developed as a consequence of another underlying medical condition, not type 1 or type 2 diabetes. The patient presents with severe nonproliferative diabetic retinopathy, a microvascular complication affecting the retina, specifically in the right eye, without any associated macular edema.

Apply this code when documentation clearly states diabetes is secondary to another condition (e.g., pancreatic disease, drug-induced) and severe nonproliferative retinopathy is present in the right eye without macular edema. Supporting documentation includes ophthalmology reports detailing the severity and location of the retinopathy, and physician notes confirming the underlying cause of diabetes.

• Always sequence the underlying condition causing the diabetes first, followed by this code.
• Distinguish carefully between "due to underlying condition" and "type 1" or "type 2" diabetes; these are distinct categories.
• Ensure the documentation specifies "severe" nonproliferative retinopathy and confirms the absence of macular edema for the right eye.
