Coma scale, best motor response, none, EMR

This code indicates a patient's complete lack of motor response to any stimulus upon presentation to the emergency department, as assessed by the Glasgow Coma Scale (GCS). It signifies the most severe level of motor impairment, suggesting profound neurological dysfunction.

This code is appropriate when documentation explicitly states a GCS motor score of 1 (no motor response) recorded at the time of the patient's arrival in the emergency department. It is typically used for patients presenting with severe head trauma, stroke, anoxic brain injury, or other critical neurological events.

• Ensure the documentation specifies "at arrival to emergency department" for the GCS assessment.
• Do not use this code if any motor response (even decerebrate or decorticate posturing) is noted.
• Always sequence this code after the primary diagnosis describing the underlying condition causing the coma.
