Diabetes due to underlying condition w oth circulatory comp

This code signifies diabetes mellitus that is a direct consequence of another underlying disease or condition, and the patient is experiencing circulatory complications other than peripheral angiopathy or foot ulcer. This includes conditions like secondary diabetes resulting from pancreatic disease, cystic fibrosis, or certain drug-induced states, where the diabetes has led to issues such as atherosclerosis, hypertension, or other vascular problems.

Apply this code when documentation clearly links the patient's diabetes to an underlying condition (e.g., pancreatitis, hemochromatosis, post-surgical pancreatectomy) and specifies circulatory complications other than those covered by more specific codes. The medical record must explicitly state the causal relationship between the underlying condition and the diabetes, as well as the presence of the circulatory complication.

• Always code the underlying condition first, followed by this code.
• Distinguish carefully from type 1 or type 2 diabetes with circulatory complications; this code is specifically for secondary diabetes.
• Ensure the documentation specifies the type of circulatory complication if not peripheral angiopathy or foot ulcer, to avoid more specific codes.
