The ER physicians will often circle acute asthma exacerbation and acute bronchitis on the T-sheet. Should I code 493.92 and 466.0, or would 493.92 capture all of it, since this is also the code for asthmatic bronchitis with acute exacerbation? If they don't dx "asthmatic bronchitis," is it still asthmatic bronchitis if they dx asthma and bronchitis at the same time? Thanks.
