This is an established patent seen in the office by his regular physician due to increasing respiratory distress for the 12 hours, unrelieved by his usual routine of Capoten. The patient has a long standing history of severe bronchial asthma, hiatal hernia with reflux and hypertension. no history of N. V. or other symptoms. What E/M code should I use?
