Answer: According to CPT, you can report an initial inpatient consultation code (99251-99255) once per inpatient admission if your physician meets the consultation criteria. Therefore, your orthopedic surgeon can bill an initial inpatient consult code during each of the patient's two admissions.
In contrast, you should use a follow-up inpatient consultation code (99261-99263) when the surgeon provides any additional consults during the same hospital stay.
For example, if the surgeon performed a consult on day one of the patient's stay, and a second consult (at the attending physician's request) on day six, you would report the first visit using an inpatient consult code, and report the second visit using a follow-up consultation code.
Remember that the orthopedist should document the request for his opinion, notes from his review of the patient, and his report back to the requesting physician.
