Answer: You should report 780.02 (Transient alteration of awareness) for this diagnosis. According to the ICD-9 manual, this code includes "temporary, recurring spells of reduced consciousness," which sounds as if it fits what your patient experienced during her visit with the internist.

If the patient stated that she actually went unconscious during the episode, you should instead report 780.09 (Alteration of consciousness; other).
