Agreed. It's also for patient convenience. More than once I was at a small medical office and was told that the doctor had prescribed a certain diagnostic test for which the facility didn't have the equipment for. So I make an appointment at a real hospital, and then make a follow-up appointment at the small medical office for reviewing the results. It's tiring.

You would have to do that anyway. Just because you are physically located in the hospital for your checkup does not mean there is magically some availability for this procedure.

They would schedule you, and you come back.
