And the little known part to all that is folks think the ER docs make all the $$$. They dont. Its the Hospital owner group. Which is consolidating every year. Pretty soon will only have 2-3 main players in the US.
I remember my surgery - i received 3 separate billings- one for the surgery center where it took place, one for the surgeon ( group) and one for the anesthesia
now the anesthesia i had 2 charges- and it was explained to me that one was for the anesthesiologist who administered ( in the room ) and the other was for the head anesthesiologist - who was there in the event something went wrong.
And as it turns out, the head anesthesiologist was also part OWNER of the Surgery Center.
