ICD-10 Code G25.5 – Other chorea (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G25.5 – Other chorea
What it is
G25.5 identifies chorea not classified elsewhere. It refers to involuntary, irregular, purposeless movements that may affect the face, limbs, or trunk.
Clinical signs
Clinical features vary; refer to documentation. Typical descriptions include brief, nonrhythmic movements that seem dance-like and may interfere with speech, posture, or coordination.
When to use this code
Use this code when the provider documents chorea and does not assign a more specific underlying cause or a different chorea category. It also fits cases labeled as other chorea or unspecified choreiform movement disorder. Check documentation for the exact neurologic diagnosis.
Do not use for
Do not use this code when the record identifies a specific chorea cause, such as Huntington disease or drug-induced movement disorder. If the documentation is unclear, check documentation rather than assuming G25.5.
Coding tip
Code the documented movement disorder exactly as stated and look for any named etiology before assigning G25.5.
