Diab due to undrl cond w diabetic autonm (poly)neuropathy

This code signifies diabetes mellitus that has developed as a consequence of another underlying disease or condition, and is complicated by damage to the autonomic nervous system. This neuropathy can affect various involuntary bodily functions, such as heart rate, blood pressure, digestion, and bladder control.

Apply this code when documentation clearly links diabetes to an underlying condition (e.g., cystic fibrosis, pancreatitis, hemochromatosis) and specifies the presence of autonomic neuropathy. The physician's notes should explicitly state "diabetes due to underlying condition" and "autonomic neuropathy" or a specific manifestation thereof.

• Always sequence the underlying condition first, followed by this code.
• Do not use this code for Type 1 or Type 2 diabetes with autonomic neuropathy; use the appropriate E10.xx or E11.xx code instead.
• Ensure the documentation specifies "autonomic" neuropathy, as other types of diabetic neuropathy (e.g., peripheral) are coded differently.
