Very much agree. This is something you learn after a hospital visit or two, and it makes no sense.
Doubly so since, as a patient undergoing examination/treatment, you have zero chance of sussing out who is who, what organization they work for, how their billing works, etc.
All you know is someone came into the room to run a test or otherwise interact with you. It's not like you can interrogate them and then refuse their services -- among other things, they don't even know how their financial org is going to bill you.
