Disorder of the autonomic nervous system, unspecified

This code signifies a general, unspecified dysfunction of the autonomic nervous system (ANS). It encompasses conditions where the sympathetic or parasympathetic nervous systems are impaired, leading to a wide range of involuntary bodily function disturbances without a more specific diagnosis.

Use this code when documentation indicates a disorder of the autonomic nervous system but lacks specificity regarding the type or cause. This is appropriate for initial evaluations or when diagnostic workup is incomplete and a more precise code cannot be assigned.

• Avoid using this code if a more specific autonomic neuropathy or dysautonomia code is available and supported by documentation.
• Query the provider for further specificity if possible, especially regarding the underlying cause or specific system affected (e.g., cardiovascular, gastrointestinal).
• Consider sequencing this code as a secondary diagnosis if the autonomic dysfunction is a manifestation of another primary condition.
