Oth diab with prolif diabetic rtnop with macular edema, bi

This code signifies a diagnosis of diabetes mellitus, other specified types, complicated by proliferative diabetic retinopathy affecting both eyes, specifically with the presence of macular edema. Proliferative diabetic retinopathy involves the growth of new, abnormal blood vessels on the retina, which are prone to bleeding and can lead to severe vision loss, further exacerbated by fluid accumulation in the macula.

Apply this code when documentation clearly indicates a patient has a form of diabetes mellitus other than type 1 or type 2 (e.g., secondary diabetes due to pancreatectomy or drug-induced diabetes) and is diagnosed with proliferative diabetic retinopathy in both eyes, with co-occurring macular edema. This code is appropriate when the physician explicitly states the bilateral involvement and the presence of macular edema.

• Ensure the documentation specifies "other specified diabetes mellitus" and not type 1 or type 2 diabetes.
• Verify that both proliferative retinopathy and macular edema are present and explicitly stated as bilateral.
• Sequence this code after the primary diabetes mellitus code if the diabetes is the underlying condition causing the retinopathy.
