Diabetes with severe nonp rtnop with 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. The patient presents with severe nonproliferative diabetic retinopathy (NPDR) affecting both eyes, further complicated by macular edema in both eyes. This indicates significant microvascular damage to the retina due to the secondary diabetes.

Apply this code when documentation clearly states diabetes is secondary to another condition (e.g., pancreatitis, cystic fibrosis, drug-induced) and the patient has severe NPDR with macular edema in both eyes. Ensure the physician explicitly links the diabetes to the underlying cause and specifies the severity and bilateral nature of the retinopathy and macular edema.

• Always sequence the underlying condition causing the diabetes first, followed by this code.
• Confirm the documentation specifies "severe" nonproliferative retinopathy and "bilateral" involvement for both retinopathy and macular edema.
• Differentiate from other forms of diabetes (Type 1, Type 2) and other stages/types of diabetic retinopathy.
