Diabetes due to underlying condition w diabetic cataract

This code signifies a form of diabetes that arises as a direct consequence of another underlying medical condition, specifically when this diabetes has led to the development of cataracts. It indicates a secondary diabetes etiology, distinct from Type 1 or Type 2, where the primary disease process is responsible for the diabetic state and the subsequent ocular complication.

Use this code when documentation clearly states that diabetes is due to an underlying condition (e.g., pancreatitis, cystic fibrosis, drug-induced) and that the patient also has a diabetic cataract. Supporting documentation includes physician notes detailing the causal link between the underlying condition and diabetes, and ophthalmology reports confirming the presence of diabetic cataracts.

• Always code the underlying condition first, followed by this diabetes code.
• Ensure documentation explicitly links the diabetes to the underlying condition and the cataract to the diabetes.
• Do not use this code for Type 1 or Type 2 diabetes with cataracts; those have specific codes.
