Diabetes due to undrl condition w oth diabetic kidney comp

This code signifies diabetes mellitus that is a direct consequence of another underlying disease or condition, rather than type 1 or type 2 diabetes, and is complicated by a kidney disorder other than diabetic nephropathy (e.g., acute kidney injury, chronic kidney disease not specified as diabetic). It indicates a secondary form of diabetes where renal complications are present.

Apply this code when documentation clearly links diabetes to an underlying condition (e.g., cystic fibrosis, pancreatitis, hemochromatosis, drug-induced) and specifies a kidney complication that is not explicitly diabetic nephropathy. The physician's notes must establish the causal relationship between the underlying condition and the diabetes, and detail the specific kidney involvement.

• Always sequence the underlying condition causing the diabetes first, followed by this code.
• Do not use this code for diabetic nephropathy (N08) or chronic kidney disease (N18.-) when it is a direct complication of type 1 or type 2 diabetes.
• Ensure the documentation differentiates "other diabetic kidney complication" from diabetic nephropathy, which has its own specific codes.
