Patient presents with unresponsiveness, altered mental status, and decreased level of consciousness.  Differential diagnosis includes coma, stupor, and vegetative state.  Onset of unresponsiveness was (sudden, gradual), and duration is documented.  Precipitating factors, if known, include (possible causes such as medication overdose, head injury, stroke, metabolic disturbance, seizure, syncope, intoxication, or infection).  Patient exhibits (absent, diminished, or purposeful) response to verbal stimuli, tactile stimuli, and painful stimuli.  Glasgow Coma Scale score is documented.  Pupillary response is (present, sluggish, fixed, dilated, or constricted) and symmetrical or asymmetrical.  Respiratory pattern is (regular, irregular, Cheyne-Stokes, or other).  Cardiovascular status including heart rate, blood pressure, and oxygen saturation is monitored.  Neurological examination reveals (presence or absence of focal neurological deficits).  Initial management includes airway management, ensuring adequate ventilation and oxygenation, circulatory support, and blood glucose monitoring.  Laboratory studies ordered include complete blood count, comprehensive metabolic panel, blood cultures, toxicology screen, and arterial blood gas.  Imaging studies such as CT scan of the head or MRI may be indicated.  Patient is being closely monitored for changes in neurological status.  Treatment plan is focused on identifying and addressing the underlying cause of unresponsiveness and providing supportive care.  Medical coding will be determined based on the final diagnosis.  Prognosis and disposition are dependent upon the etiology of the unresponsiveness and the patient's response to treatment.
