G13: Systemic atrophies primarily affecting central nervous system in diseases classified elsewhere

The ICD-10 code range G13 pertains to systemic atrophies primarily affecting the central nervous system in diseases classified elsewhere. This means these conditions involve a generalized wasting or decrease in size of the tissues in the central nervous system, which is the brain and spinal cord. These atrophies are usually secondary to other diseases, which means that they are consequences of these illnesses rather than primary conditions. When atrophy occurs, it often results in loss of function in the nervous system, leading to a variety of symptoms that can include difficulty with movement and coordination, intellectual changes, alterations in sensation, and other neurological problems. The progression of these conditions greatly depends on the underlying disease causing the atrophy. As these conditions involve the central nervous system, they can significantly impact a person's overall health and quality of life.
