Diabetes due to underlying condition w diabetic polyneurop

This code signifies a form of diabetes mellitus that develops as a direct consequence of another underlying medical condition, rather than being Type 1 or Type 2 diabetes. A key feature of this specific diagnosis is the presence of diabetic polyneuropathy, a type of nerve damage affecting multiple peripheral nerves, caused by the diabetes.

Apply this code when documentation clearly indicates diabetes mellitus resulting from a secondary cause (e.g., pancreatic disease, cystic fibrosis, drug-induced) and the patient also exhibits symptoms or diagnostic findings consistent with polyneuropathy directly attributed to this secondary diabetes. The medical record should specify both the underlying condition causing the diabetes and the presence of polyneuropathy.

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