Rheumatic chorea without mention of heart involvement

This code signifies Sydenham's chorea, a neurological disorder characterized by involuntary, jerky movements, that occurs as a delayed complication of rheumatic fever. It specifically indicates that there is no documented evidence of cardiac involvement, such as rheumatic heart disease, associated with the chorea.

Apply this code when a patient presents with a diagnosis of rheumatic chorea and the medical record explicitly states or clearly implies the absence of any co-occurring rheumatic heart condition. Documentation should confirm the chorea's rheumatic origin and lack of cardiac manifestations.

• Do not use this code if any cardiac involvement, past or present, is documented as related to the rheumatic process.
• Distinguish from other forms of chorea (e.g., Huntington's chorea) which have different etiologies.
• Ensure the documentation clearly links the chorea to a history of rheumatic fever.
