Glasgow coma scale score 9-12, 24+hrs

This code indicates a moderately impaired level of consciousness, as measured by the Glasgow Coma Scale (GCS) score between 9 and 12, specifically assessed at least 24 hours after a patient's admission to the hospital. It reflects a persistent neurological status following an initial period of hospitalization.

This code is used when a patient's GCS score is documented as 9, 10, 11, or 12 on or after the second day of hospitalization. Documentation must clearly state the GCS score and the timeframe relative to admission. It is typically applied in cases of traumatic brain injury, stroke, or other neurological conditions requiring ongoing monitoring of consciousness.

• Always sequence this code after the definitive diagnosis for the underlying condition causing the altered mental status.
• Ensure the medical record explicitly states the GCS score and the "24 hours or more after admission" timeframe to support code assignment.
• Do not use this code if the GCS score was assessed within the first 24 hours of admission; a different GCS code would apply.
