ICD-10 Code I02.0 – Rheumatic chorea with heart involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I02.0 – Rheumatic chorea with heart involvement
What it is
This code identifies rheumatic chorea occurring together with cardiac involvement from rheumatic fever. Use it when the record shows involuntary choreiform movements and evidence of rheumatic heart disease.
Clinical signs
Clinical features include rapid, irregular, involuntary movements, poor coordination, and possible emotional lability. Heart involvement may be documented as rheumatic carditis or valvular disease; clinical features vary, refer to documentation.
When to use this code
Use I02.0 when the provider documents rheumatic chorea and confirms heart involvement in the same episode or history. It may appear in patients with Sydenham chorea and concurrent rheumatic cardiac findings. If the chart does not clearly link the neurologic and cardiac findings, check documentation.
Do not use for
Do not use this code for chorea without rheumatic heart involvement, or for non-rheumatic movement disorders. If the record only supports rheumatic carditis or heart disease alone, choose the appropriate separate code.
Coding tip
Confirm both components in the note: rheumatic chorea and heart involvement must be documented for I02.0.
