Coma scale, eyes open, to pain, in the field

This code indicates a specific finding during a neurological assessment using the Glasgow Coma Scale (GCS) in an out-of-hospital setting. Specifically, it describes a patient who opens their eyes only in response to a painful stimulus, as documented by emergency medical services (EMS) personnel. This finding suggests a moderate level of impaired consciousness.

This code is used when EMS documentation clearly states the patient's GCS eye-opening component as "to pain" and the assessment was performed in the field (e.g., ambulance, scene of accident). It is appropriate for patients presenting with altered mental status due to trauma, medical emergencies, or other conditions requiring pre-hospital care and neurological evaluation.

• Ensure documentation explicitly states "in the field" or "pre-hospital" to differentiate from in-hospital assessments.
• This code represents only one component of the GCS; additional codes for verbal and motor responses should be reported if documented.
• Do not use if the eye-opening response was spontaneous, to speech, or absent; select the appropriate GCS eye-opening code.
