Other disorders of autonomic nervous system
ICD-10 G90.8 is a billable code used to indicate a diagnosis of other disorders of autonomic nervous system.
G90.8 encompasses a variety of conditions affecting the autonomic nervous system (ANS), which regulates involuntary bodily functions such as heart rate, blood pressure, digestion, and respiratory rate. Disorders classified under this code may include complex pain syndromes, dysautonomia, and other autonomic dysfunctions that do not fit into more specific categories. Patients may present with symptoms such as orthostatic hypotension, gastrointestinal dysmotility, and abnormal sweating. Hydrocephalus, while primarily a neurological condition, can also lead to autonomic dysfunction due to increased intracranial pressure affecting brainstem function. Accurate diagnosis often requires a comprehensive evaluation, including autonomic testing, to differentiate these disorders from other neurological conditions. The complexity of these disorders can lead to significant morbidity, necessitating a multidisciplinary approach for management and treatment. Clinicians must be vigilant in documenting the specific symptoms and diagnostic tests performed to support the use of this code.
Detailed neurological examination findings, results from autonomic testing, and patient history.
Patients presenting with unexplained syncope, chronic pain syndromes, or gastrointestinal dysmotility.
Ensure all relevant symptoms and diagnostic tests are documented to support the diagnosis.
Comprehensive pain assessments, treatment plans, and response to therapies.
Patients with chronic pain syndromes that may have autonomic components.
Document the relationship between pain symptoms and autonomic dysfunction clearly.
Used when specific autonomic testing procedures are performed but not listed elsewhere.
Detailed report of the procedure and findings.
Neurology specialists should ensure that the procedure is well-documented to support the unlisted code.
G90.8 includes a variety of autonomic disorders that do not have a more specific code, such as dysautonomia, complex pain syndromes, and autonomic dysfunctions related to other conditions.
To ensure accurate coding, document all relevant symptoms, diagnostic tests, and the clinical rationale for the diagnosis. Avoid using G90.8 if a more specific code is available.
