Diabetes due to underlying condition w oth diabetic arthrop

This code signifies diabetes mellitus that is a direct consequence of another underlying disease or condition, specifically when the patient also presents with arthropathy (joint disease) that is attributed to the diabetes. The diabetes is not type 1 or type 2, but secondary to another primary illness.

Apply this code when documentation clearly states diabetes is secondary to another condition (e.g., cystic fibrosis, pancreatitis, hemochromatosis, pancreatectomy) and the patient is experiencing joint complications directly related to this secondary diabetes. The physician must explicitly link the arthropathy to the diabetes.

• Always sequence the underlying condition causing the diabetes first, followed by this code.
• Ensure the documentation specifies "other diabetic arthropathy" and not a more specific type of arthropathy (e.g., Charcot's joint, which has its own code).
• Do not use this code for Type 1 or Type 2 diabetes with arthropathy; those have their own specific combination codes.
