Coma scale, best motor response, abnormal flexion, 24+hrs

This code indicates a patient exhibiting an abnormal flexion motor response, specifically decorticate posturing, as part of their Glasgow Coma Scale (GCS) assessment. This finding has persisted for at least 24 hours following their admission to the hospital, suggesting a sustained neurological impairment.

Apply this code when documentation clearly states a GCS motor score reflecting abnormal flexion (e.g., decorticate rigidity) that has been present for a full day or longer since the patient's hospital admission. This is typically seen in patients with significant cerebral hemisphere damage.

• Ensure the medical record explicitly documents "abnormal flexion" or "decorticate posturing" as the best motor response, not just a GCS score.
• Verify the duration of this finding; it must be 24 hours or more post-admission.
• This code is for a specific GCS component and should be sequenced after the primary diagnosis causing the altered mental status.
