Systemic atrophies primarily affecting central nervous system in diseases classified elsewhere
Chapter 6:Diseases of the nervous system
ICD-10 G13 is a billable code used to indicate a diagnosis of systemic atrophies primarily affecting central nervous system in diseases classified elsewhere.
G13 encompasses a range of systemic atrophies that primarily affect the central nervous system (CNS) and are classified under other diseases. This includes hereditary and degenerative conditions such as Huntington's disease, various forms of ataxia, and motor neuron diseases. These conditions are characterized by progressive degeneration of nerve cells, leading to motor dysfunction, cognitive decline, and other neurological symptoms. Huntington's disease, for instance, is a genetic disorder that results in the breakdown of nerve cells in the brain, causing movement disorders and cognitive decline. Ataxias, which can be hereditary or acquired, lead to coordination and balance issues due to cerebellar degeneration. Motor neuron diseases, such as amyotrophic lateral sclerosis (ALS), involve the degeneration of motor neurons, resulting in muscle weakness and atrophy. Accurate coding for G13 requires a thorough understanding of the underlying conditions and their manifestations, as well as careful documentation of the patient's clinical presentation and history.
Detailed neurological examination findings, family history, and genetic testing results.
Patients presenting with progressive motor dysfunction, cognitive decline, or coordination issues.
Ensure that the documentation clearly differentiates between hereditary and acquired conditions.
Genetic testing results, family pedigree, and detailed patient history.
Patients with a family history of neurological disorders or symptoms suggestive of hereditary ataxias.
Documentation should include genetic counseling notes and any relevant family history.
Used for follow-up visits for patients with G13-related conditions.
Detailed history, examination, and medical decision-making.
Neurologists should document neurological assessments thoroughly.
G13 includes systemic atrophies primarily affecting the CNS due to hereditary and degenerative diseases, such as Huntington's disease, various ataxias, and motor neuron diseases.
Documentation should include family history and genetic testing results to differentiate hereditary atrophies from acquired conditions.
