R40.2111

Glasgow coma scale score, eyes open, never, at arrival in emergency department

R40.2111 is a clinical mapping code used to document a specific component of the Glasgow Coma Scale (GCS) assessment: the 'Eyes Open' response. A score of 'never' (1 point) signifies that the patient does not open their eyes in response to any external stimuli, including verbal commands or physical pressure (formerly designated as 'pain'). This specific code denotes the assessment finding specifically at the time of arrival in the emergency department (ED). This measurement is critical for establishing a baseline neurological status in patients with acute head injury, stroke, poisoning, or other forms of altered consciousness. It is part of the GCS sub-scoring system (E1, V, M) used to calculate the total GCS score, which assists in categorizing the severity of brain injury and guiding immediate triage and treatment protocols.

Clinical Symptoms

Persistent eye closure despite loud verbal stimuli
No eye opening in response to physical pressure (supraorbital pressure or nail bed pressure)
Absence of spontaneous eye opening
Lack of blinking or tracking of objects
Deep unconsciousness
Areflexic state relative to visual stimuli
Potential signs of concomitant trauma (e.g., raccoon eyes, Battle sign)
Associated respiratory depression or abnormal breathing patterns
Presence of abnormal motor posturing (decorticate or decerebrate) often accompanying low eye scores

Common Causes

Severe Traumatic Brain Injury (TBI)
Massive intracerebral hemorrhage
Large-scale ischemic stroke
Global hypoxic-ischemic brain injury (post-cardiac arrest)
Severe metabolic encephalopathy (e.g., profound hypoglycemia, uremia)
Acute drug overdose (e.g., opioids, benzodiazepines, barbiturates)
Status epilepticus or postictal state
Severe central nervous system infection (meningitis or encephalitis)
Acute herniation syndrome
Fulminant hepatic failure leading to Grade IV encephalopathy

Documentation & Coding Tips

Document individual Glasgow Coma Scale components separately to justify the eye-opening sub-score.

Example: Patient arrived at the emergency department via ambulance after a fall from 15 feet. On arrival, GCS components were assessed: Eye opening: 1 (Never), Verbal response: 1 (None), Motor response: 2 (Extension to pain). Total GCS 4. The lack of eye opening (R40.2111) reflects severe traumatic brain injury requiring immediate ICP monitoring and neurosurgical evaluation.

Billing Focus: Timing specificity (at arrival) and component specificity (eyes open, never).

Distinguish between arrival status and subsequent assessments during the encounter.

Example: Neurological assessment at arrival in the ED showed no eye opening even to vigorous painful stimuli (GCS Eyes: 1). By the 4-hour mark, following administration of Narcan for suspected opioid overdose, eyes opened to speech (GCS Eyes: 3). Initial coding must reflect R40.2111 for the arrival status.

Billing Focus: Chronological assessment mapping to seventh-character designations in the R40.2- category.

Clarify the presence of confounding factors such as chemical sedation or paralytics used in the field.

Example: Patient was intubated and sedated with Etomidate and Succinylcholine by EMS prior to arrival. Neurological exam at arrival showed eyes never open (GCS Eyes: 1). Note: Score reflects post-sedation status but is documented as the initial ED presentation for R40.2111 coding purposes.

Billing Focus: Clarification of whether the GCS score is a true reflection of the patient's neurological state or medication-induced.

Link the GCS sub-score to the primary diagnosis to support medical necessity for procedures.

Example: The patient's failure to open eyes at arrival (R40.2111) in the setting of an acute large-territory MCA infarct (I63.311) necessitated immediate intubation (31500) for airway protection and transfer to the neuro-ICU.

Billing Focus: Establishing medical necessity for high-intensity procedures (e.g., intubation, mechanical ventilation).

Use standardized GCS terminology to avoid ambiguity in the clinical record.

Example: Initial ED triage note: Patient non-responsive to verbal commands; eyes remained closed despite deep sternal rub. GCS eyes open: 1 (never). Diagnosed with acute hypoxic-ischemic encephalopathy (G93.1) following cardiac arrest.

Billing Focus: Aligning clinician terminology with ICD-10-CM 'never' and 'at arrival' descriptors.

Relevant CPT Codes

99285 - Emergency department visit, high medical decision making
A patient with GCS eyes never open (R40.2111) at arrival represents a high-complexity case requiring extensive data review and high risk of morbidity/mortality.
99291 - Critical care, first 30-74 minutes
Patients scoring 1 on eye opening at arrival usually require critical care interventions (e.g., airway management, hemodynamic stabilization).
31500 - Intubation, endotracheal, emergency procedure
A GCS total score typically associated with R40.2111 often falls below 8, requiring emergent airway protection.
70450 - CT head or brain; without contrast material
Immediate imaging is the standard of care for any patient presenting with depressed consciousness to the ED.
99213 - Office or other outpatient visit, established patient, low MDM
While R40.2111 is an acute ED code, follow-up for survivors may occur in outpatient settings to monitor neuro-recovery, though the acute code would no longer apply.
61107 - Burr hole(s) for ventricular puncture
Severe TBI or hemorrhage leading to coma (R40.2111) often requires ICP monitoring via burr hole.
94002 - Ventilation assist and management, initial day
Most patients with no eye opening at arrival require mechanical ventilation.
99205 - Office or other outpatient visit, new patient, high MDM
Used for new patient consultations in neurology for complex post-comatose sequelae evaluation.
95816 - Electroencephalogram (EEG); including recording in coma
EEG is used to evaluate brain activity and rule out non-convulsive status epilepticus in comatose patients.
36620 - Arterial catheterization or cannulation for sampling, monitoring or transfusion
Required for real-time blood pressure monitoring in critically ill neurological patients.
