Rheumatic chorea
Chapter 9:Diseases of the circulatory system
ICD-10 I02 is a used to indicate a diagnosis of rheumatic chorea.
Rheumatic chorea, also known as Sydenham's chorea, is a neurological disorder characterized by rapid, unintentional movements and emotional disturbances, often occurring as a complication of rheumatic fever, which is triggered by streptococcal infections. The condition primarily affects children and adolescents, typically manifesting 1 to 6 months after the initial streptococcal infection. Clinically, patients may present with involuntary movements, emotional lability, and behavioral changes. The basal ganglia, a group of nuclei in the brain responsible for coordinating movement, are primarily involved in this disorder. Disease progression can vary, with symptoms potentially lasting for weeks to months, and in some cases, may lead to chronic issues. Diagnosis is primarily clinical, supported by a history of rheumatic fever, neurological examination, and exclusion of other movement disorders. Laboratory tests may include throat cultures or rapid antigen tests for streptococcus, and elevated anti-streptolysin O titers can support the diagnosis. Early recognition and management are crucial to prevent long-term complications, including the potential for cardiac involvement due to rheumatic heart disease.

I02 specifically covers rheumatic chorea, which is a movement disorder that arises as a complication of rheumatic fever. It is characterized by involuntary movements and emotional disturbances following a streptococcal infection.
I02 should be used when the patient presents with chorea specifically linked to rheumatic fever. It is important to differentiate it from other movement disorders and to ensure a documented history of rheumatic fever or streptococcal infection.
Documentation should include a clear history of rheumatic fever, clinical findings of chorea, neurological assessments, and any relevant laboratory results indicating streptococcal infection.
