Can we bill two initial inpatient visit, if the patient is admitted by provider belong to one specialty and bill for 99223. On the next day, he consulted a physician of different specialty of the same physician group and he provided the service to the patient. Since the insurance is Medicare, they will not pay for consultation code. Should we choose 99221-3 as this is the first visit for the physician or 99231-3, since they belong to same group?
