Diabetes with severe nonp rtnop with 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, characterized by significant retinal damage without new blood vessel growth, specifically affecting the macula of the right eye with associated edema.

Use this code when documentation clearly states diabetes is secondary to another condition (e.g., pancreatitis, cystic fibrosis, drug-induced) and the patient has severe nonproliferative diabetic retinopathy with macular edema in the right eye. Supporting documentation should include the specific underlying condition causing the diabetes, ophthalmological findings detailing the severity of retinopathy, and laterality.

• Always sequence the underlying condition causing the diabetes first, followed by this code.
• Ensure documentation specifies "severe nonproliferative" and "macular edema" for the right eye; codes exist for moderate, mild, and without macular edema.
• Verify the type of diabetes is explicitly stated as "due to underlying condition" to differentiate from type 1 or type 2 diabetes.
