Coma scale, best motor, abnormal flexion, unspecified time

This code indicates a specific finding during a neurological assessment, where a patient exhibits an abnormal flexion response to painful stimuli, such as decorticate posturing. This motor response is a component of the Glasgow Coma Scale (GCS) and suggests significant neurological dysfunction. The "unspecified time" indicates that the timing of this assessment relative to the patient's admission or event is not documented.

Use this code when documentation clearly states an abnormal flexion motor response was observed during a GCS assessment, and the specific timing of this assessment (e.g., in the field, upon arrival, 24 hours post-admission) is not specified. This is typically seen in patients with acute brain injury, stroke, or other conditions causing altered mental status.

• Ensure documentation explicitly states "abnormal flexion" or describes decorticate posturing as the best motor response.
• Do not use this code if the timing of the GCS assessment is clearly documented (e.g., "in the field," "upon arrival"), as more specific codes exist.
• This code is a symptom code and should be sequenced after the definitive diagnosis for the underlying neurological condition, if known.
