Other disorders of nervous system not elsewhere classified (G98)
The ICD-10 code section G98 covers other disorders of the nervous system not elsewhere classified, including specific conditions like neurogenic arthritis (G98.0) and a broad set of neurological disorders under G98.8. These codes are used to identify nervous system problems that don’t fit into more defined categories.
The code G98.0neurogenic arthritis, also known as neurogenic neuropathic arthropathy, indicating joint damage caused by nervous system impairment. The code G98.8fungal neuritis, bacterial neuritis, neurological disorders caused by ethanol, and HIV with neurological disease. Using these codes helps medical coders accurately classify nervous system conditions when standard categories don't apply, providing clarity in diagnosis coding for unusual or complex neurological problems.
