The 2022 No Surprises act means you should not be getting out of network bills for anesthesiologists:
we really need to eliminate this absolutely ludicrous distinction legislatively.
EDIT: i stand corrected with regard to anesthesiologists. I maintain that hospitals and providers are quickly learning how to maneuver patients into scenarios where they will be subjected to surprise billing anyway. I also maintain that the concept of out-of-network services is mostly ridiculous, since the median patient is very rarely in a position to make actual choices about most of the care they receive.

See top right of page 3 and the third paragraph of #7 on page 10.
Is there a concept of illegal agreement clauses in US? Where even after signing an agreement the signee can claim that such and such clause was illegal and if the court confirms it the whole agreement (or just the clause) is void?
