2. Single point billing - if you go to Hospital ABC, your bill will be from Hospital ABC. You will not get 5 bills from 3 different providers. It's up to the hospital, doctor's office, whatever, to distribute the funds.
At the very least upon discharge tell you which doctors/practices you'll be getting a bill from
A lot of people think they go to the hospital and they get a hospital bill and are surprised to get a bill from half a dozen different practices (5 of which they've never even heard of before)
