Code Description

ICD-10 E11.359 is a billable code used to indicate a diagnosis of type 2 diabetes mellitus with proliferative diabetic retinopathy without macular edema.

Key Diagnostic Point:

E11.359 refers to a specific complication of Type 2 diabetes mellitus characterized by the presence of proliferative diabetic retinopathy (PDR) without associated macular edema. PDR is a severe form of diabetic retinopathy that occurs when new blood vessels grow in the retina, which can lead to vision loss. This condition is often a result of chronic hyperglycemia and poor glycemic control, typically indicated by elevated HbA1c levels. Patients with PDR may experience symptoms such as blurred vision, floaters, or sudden vision loss. Management of this condition often requires a multidisciplinary approach, including regular ophthalmologic evaluations and potential interventions such as laser photocoagulation. Insulin management is crucial for controlling blood glucose levels, and achieving optimal HbA1c levels is essential to prevent further complications. The absence of macular edema distinguishes this code from other diabetic retinopathy codes, emphasizing the need for precise documentation and coding to reflect the patient's condition accurately.
