I noticed that if a hospital encounter is entered as an addendum, AC does not recognize that the patient was seen, even if a bill was generated with a CPT hospital encounter code. Sure, patient not seen for three years in the OFFICE, but just seen last week in the HOSPITAL. When I do searches later, for example, of patient's seen in the last two years, this patient would not show up on that list... Not necessary an issue, but just sharing...
