Actually - this is an effort to bring the free market into the system. Ie, doctors have to tell you UP FRONT what they will charge you, and cannot just drop by your room while you are out and then bill you for the evaluation.
You can then decide if the specialist out of network is worth it, or go in-network or to your medical / medicare provider and work with them.
In particular (for those who don't know) California's law protects you ONLY if you go to an IN NETWORK facility. If you do, then if somehow an out of network doctor drops by or helps with the knock out gas or whatever, they can't then bill you for the "out of network" service. It turns out this was pretty common (my guess is some kind of kickback to the in-network facility to allow this).
You can still be charged or over charged by any provider if you agree to be, and sometimes still even if you don't (ambulance ride to out of network)
