Which states specifically have these laws? What's the typical legal name for these laws? Couldn't find anything on this in a few quick Google searches.
In Florida you can checkout Florida Statute 395.301 (Price transparency;itemized patient statement or bill;patient admission status notification).
I know this off hand, and don’t have the time but from there you could probably find a few websites that will reference comparable laws for each state, if they exist.
Law is an unforgiving beast so you would always want to refer to the source law they cite, and finding case law (much more difficult task) which references said Law and see how it’s applied/interpreted in practice.
What you linked is certainly much more practical for educational/informational purposes.
