An established patient with chronic COPD and/or asthma has increased shortness of breath and dyspnea. The doctor's documentation does not state exacerbation although increased prednisone or other medication may be prescribed. Is it correct to code for the symptoms which were the chief complaint and list COPD or asthma as a third diagnosis or do you just code for the chronic disease that has those symptoms?

Also if it is mentioned that the patient has COPD and Asthma, is 493.2X always correct?
