Unspecified abnormal involuntary movements

This code signifies the presence of involuntary muscle contractions or movements that are not further specified as to their type or underlying cause. It encompasses a broad range of motor phenomena, such as tremors, tics, dystonia, chorea, or myoclonus, when the specific nature of the movement disorder is not documented.

Use this code when the medical record clearly indicates abnormal involuntary movements but lacks sufficient detail to assign a more specific code. This often occurs in initial assessments or when a definitive diagnosis of the movement disorder has not yet been established. Documentation should explicitly state "abnormal involuntary movements, unspecified" or similar phrasing.

• Avoid using this code if a more specific type of involuntary movement (e.g., tremor, tic, dystonia) is documented.
• Query the provider for clarification if the documentation describes involuntary movements but doesn't specify the type or cause.
• This code should be considered a temporary diagnosis; strive for greater specificity as more information becomes available.
