I care what my insurance company pays. I’d expect them to negotiate a % of list and I would know from there. People should be aware of what this all costs since so many with insurance think it is all but free and I’m not so sure they don’t think it is all free somehow.
Sure, because that's what drives their premiums.
Problem is they're going to consider that proprietary information because they don't want the other insurers to know what kind of deal they got. Neither does the hospital, BTW.
