Other disorders of nervous system not elsewhere classified
Chapter 6:Diseases of the nervous system
ICD-10 G98 is a billable code used to indicate a diagnosis of other disorders of nervous system not elsewhere classified.
The G98 code encompasses a variety of disorders affecting the nervous system that do not fit neatly into other specific categories. This includes pain syndromes such as complex regional pain syndrome (CRPS), which is characterized by severe pain, swelling, and changes in skin color and temperature in the affected limb. Autonomic disorders, such as dysautonomia, which can lead to abnormal heart rate, blood pressure fluctuations, and gastrointestinal issues, are also included. Hydrocephalus, a condition marked by an accumulation of cerebrospinal fluid within the ventricles of the brain, can lead to increased intracranial pressure and neurological deficits. Other disorders may include conditions like post-polio syndrome, which manifests as new muscle weakness and fatigue in individuals who previously had polio. The diversity of conditions classified under G98 necessitates careful clinical evaluation and documentation to ensure accurate coding and appropriate treatment.
Detailed patient history, neurological examination findings, and diagnostic test results.
Patients presenting with chronic pain syndromes, autonomic dysfunction, or post-surgical complications.
Ensure that all relevant symptoms and diagnostic criteria are documented to support the use of G98.
Comprehensive pain assessments, treatment plans, and response to therapies.
Management of complex regional pain syndrome or neuropathic pain.
Document the multidisciplinary approach to treatment and any co-existing conditions.
Used for follow-up visits for patients with G98 diagnoses.
Document the patient's history, examination findings, and treatment plan.
Neurology specialists should ensure comprehensive documentation to support the visit level.
G98 should be used when a patient presents with a neurological disorder that does not fit into a more specific category. It is essential to ensure that the documentation supports the use of this code.
