Other disorders of autonomic nervous system

This code represents a range of autonomic nervous system dysfunctions that do not fit more specific diagnostic categories. It encompasses conditions where there is impaired regulation of involuntary bodily functions, such as heart rate, blood pressure, digestion, and temperature control, due to autonomic neuropathy or dysautonomia of an unspecified or "other" type.

Use this code when documentation indicates a disorder of the autonomic nervous system that is not specifically classified elsewhere in ICD-10-CM. This includes conditions like generalized dysautonomia, autonomic neuropathy not specified as primary or secondary to a known disease, or other ill-defined autonomic disturbances. Documentation should clearly state an autonomic disorder that lacks a more precise code.

• Always attempt to code to a more specific autonomic disorder if documented (e.g., G90.0- for idiopathic peripheral autonomic neuropathy, G90.1 for familial dysautonomia).
• Review medical records for underlying causes or associated conditions, as these may need to be coded first or in conjunction.
• Avoid using this code if the autonomic dysfunction is a symptom of another primary condition that has a more specific code (e.g., diabetic autonomic neuropathy should be coded with E11.43).
