Polyneuropathy in diabetes

This code signifies a neurological disorder characterized by widespread damage to peripheral nerves, specifically occurring as a complication of diabetes mellitus. It typically presents with symmetrical sensory, motor, or autonomic dysfunction, often starting in the extremities.

Apply this code when documentation clearly indicates a diagnosis of polyneuropathy directly attributed to a patient's diabetic condition. Supporting documentation should include physician notes detailing neurological symptoms, findings consistent with peripheral nerve damage, and a confirmed diagnosis of diabetes.

• Always code the underlying diabetes first, followed by this code to show the causal relationship.
• Ensure the physician's documentation explicitly links the polyneuropathy to diabetes; avoid assuming causality.
• Differentiate from mononeuropathy or other non-diabetic neuropathies.
