Febrile seizure

The attending physician had requested an inpatient consultation on a 10-year-old admitted for an appendectomy. Postoperatively, the patient developed a fever and seizures. An initial consultation diagnosis was febrile seizure. Now, on day 5, the child’s temperature has returned to normal but the child has had a recurrence of seizures of increased severity. A follow up hospital consultation is requested (same consultant). He documents a detailed history and physical exam with high medical decision making. What is the correct E/M code for the follow up consultation?
