Type 2 diabetes w diabetic autonomic (poly)neuropathy

This code signifies type 2 diabetes mellitus complicated by damage to the autonomic nervous system, which controls involuntary bodily functions. This neuropathy can affect various systems, including cardiovascular, gastrointestinal, genitourinary, and sudomotor functions, leading to a wide range of symptoms. It represents a serious long-term complication of poorly controlled diabetes.

Use this code when documentation clearly indicates a diagnosis of type 2 diabetes and a co-occurring diabetic autonomic neuropathy. Clinical notes should specify symptoms or diagnostic findings consistent with autonomic dysfunction, such as gastroparesis, orthostatic hypotension, erectile dysfunction, or sudomotor abnormalities, attributed to the patient's diabetes.

• Always sequence the diabetes code first, as it is the underlying condition causing the neuropathy.
• Ensure the documentation explicitly links the autonomic neuropathy to the diabetes; avoid coding based on assumption.
• Distinguish from other diabetic neuropathies (e.g., peripheral polyneuropathy) which have different codes.
