A hospital billing manager asked: If we have a public inpatient that is discharged from the brain injury unit to the outpatient clinic for follow up (at this point no previous Medicare billing would have taken place as they were a public patient) and the GP writes a specific referral for the patient to see a specialist post inpatient discharge (different specialist from their inpatient stay).  The patient is seen in the outpatient clinic for > 1 hr.  Can we bill a 132, given that no previous billing has occurred?  The factors here are that the patient is referred to a new service by a GP; no previous 132 has been raised.
