Abnormal head movements

This code signifies involuntary, unusual, or uncontrolled movements of the head. These movements can manifest as tremors, tics, dystonia, or other dyskinesias affecting the head and neck region. It indicates a neurological sign rather than a specific diagnosis.

Assign this code when documentation explicitly states abnormal head movements without a more specific diagnosis for the underlying cause. This is appropriate for initial evaluations or when the etiology of the head movement is still under investigation. Supporting documentation includes physician notes describing observed head tremors, tics, or other involuntary head motions.

• Do not use this code if a more specific diagnosis for the head movement (e.g., torticollis, essential tremor) is documented.
• Always query for the underlying cause if not clearly documented, as this code represents a symptom.
• Consider sequencing this code after the primary diagnosis if the abnormal head movement is a manifestation of another condition.
