Other chorea

This code represents various forms of chorea that are not specifically classified elsewhere. Chorea is a neurological disorder characterized by involuntary, irregular, unpredictable, brief, and rapid movements that flow from one body part to another. These movements can affect the face, trunk, and limbs, often interfering with voluntary actions.

Use this code for diagnoses of chorea that do not fit the criteria for Huntington's chorea, rheumatic chorea, or Sydenham's chorea. This includes chorea due to metabolic disorders, drug-induced chorea, or other specified causes where a more specific ICD-10-CM code is not available. Documentation should clearly state the diagnosis of chorea and rule out the conditions listed in the Excludes1 note.

• Always review the "Excludes1" notes carefully to avoid incorrect co-coding with conditions like Huntington's or rheumatic chorea.
• Ensure the physician's documentation specifies the type of chorea if known, and if it's not one of the excluded types, then this code is appropriate.
• Consider additional codes for underlying causes of chorea (e.g., drug toxicity, metabolic disorders) if documented, following sequencing guidelines.
