The coding advice given in “Hospital admission and discharge” [Coding & Documentation, January 2007] was incorrect. CPT defines hospital admission as the first encounter between the physician and the patient at the site of service, regardless of the calendar date the patient becomes an inpatient. In this case, the patient was assigned to inpatient status at 11 p.m. but was not seen by the physician until the following morning. The physician then discharged the patient later that day, resulting in a same-day admission/discharge service, which should be reported with a code from the series 99234–99236.
