On a recent audit in my department I was marked down for having too many DX codes that they felt did not affect anesthesia. If my provider puts the dx in the pre-op evaluation I enter it in the charges. I don't feel that it is up to me to determine if that comorbidity "affects" the anesthesia. I felt it was interesting the auditor felt that smoking, hypothyroidism and DM were not important in the anesthesia process. I have done some research to find documentation that supports adding the comorbidities and not finding anything. Any suggestions?
