Other disorders of autonomic nervous system
ICD-10 G90.89 is a billable code used to indicate a diagnosis of other disorders of autonomic nervous system.
The G90.89 code encompasses a variety of conditions that affect 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 neatly into more specific categories. Patients may present with symptoms such as orthostatic hypotension, gastrointestinal dysmotility, and abnormal sweating. Hydrocephalus, while primarily a disorder of cerebrospinal fluid dynamics, can also impact autonomic regulation due to increased intracranial pressure affecting brainstem function. Accurate diagnosis often requires a multidisciplinary approach, including neurologists, pain specialists, and autonomic testing. The complexity of these disorders can lead to significant challenges in management and treatment, necessitating thorough documentation to support the diagnosis and any associated treatments.
Detailed neurological examination findings, autonomic testing results, and symptom history.
Patients presenting with unexplained syncope, chronic pain syndromes, or gastrointestinal dysmotility.
Neurologists should ensure that all relevant tests are documented to support the diagnosis of autonomic dysfunction.
Comprehensive pain assessments, treatment plans, and responses to therapies.
Patients with chronic pain syndromes that may have an autonomic component, such as fibromyalgia.
Pain specialists must document the relationship between pain symptoms and autonomic dysfunction to justify treatment approaches.
Used when specific autonomic testing procedures are not available.
Detailed explanation of the procedure and rationale for its necessity.
Neurologists should ensure that the unlisted code is justified with comprehensive documentation.
G90.89 includes a variety of autonomic disorders that do not fit into more specific categories, such as dysautonomia, complex pain syndromes, and autonomic dysfunction associated with other neurological conditions.
