Diabetes due to underlying condition w unsp complications

This diagnosis code signifies diabetes mellitus that has developed as a direct consequence of another primary medical condition, rather than being Type 1 or Type 2 diabetes. The specific underlying cause is known, but the diabetes itself has not yet manifested with any specified complications. This includes conditions like cystic fibrosis-related diabetes or pancreatitis-induced diabetes.

Assign this code when documentation clearly links diabetes to an identifiable underlying disease, and there are no documented acute or chronic complications directly attributable to the diabetes. Supporting documentation should explicitly state the underlying condition causing the diabetes (e.g., "diabetes secondary to hemochromatosis").

• Always sequence the underlying condition first, followed by this diabetes code.
• Avoid using this code if the diabetes is Type 1, Type 2, gestational, or drug/chemical-induced; specific codes exist for those types.
• If any complications of diabetes are documented (e.g., neuropathy, nephropathy), a more specific code from the E08 category with complications should be used.
