Coma scale, best motor response, none, 24+hrs

This code indicates a patient's motor response on the Glasgow Coma Scale (GCS) is "none" (score of 1) when assessed 24 hours or more after their admission to the hospital. It signifies the most severe level of motor impairment, suggesting a profound neurological deficit. This finding is often associated with severe brain injury or other critical neurological conditions.

Use this code when documentation explicitly states a GCS motor score of 1 (none) and specifies that this assessment occurred at least 24 hours post-hospital admission. This is typically found in neurological assessments, critical care notes, or progress notes detailing the patient's neurological status over time. It is crucial for tracking the persistence of severe neurological impairment.

• Ensure the documentation clearly specifies "none" for best motor response and the timeframe of "24 hours or more after hospital admission."
• This code is for the best motor response; do not use if a higher motor response was observed at any point during the assessment period.
• Always sequence this code after the primary diagnosis indicating the underlying cause of the coma or neurological impairment.
