VI: Diseases of the nervous system
G90-G99: Other disorders of the nervous system
The ICD-10 group range G90-G99 encompasses a variety of conditions referred to as "Other disorders of the nervous system". These involve issues with the nervous system, which includes the brain, spinal cord, and the nerves extending throughout the body. Disorders in this range can happen due to various factors like genetic issues, infections, injury, or conditions that progressively damage the nervous system. Symptoms vary widely depending on the specific disorder and may include problems with movement, sensation (like touch or taste), or cognition. Disease progression also varies, with some disorders being stable and others involving steady deterioration. Understanding and management of these disorders often require specialized neurological expertise.
