The charged amount helps to set the Usual & Customary fee for each area. Usual & Customary fees charged are used to determine out of network benefits for some insurance companies. So there is no specific place to go to find the magic fee for a particular service.
I'm probably not going to make any friends when I say this, but even healthcare is a business. When offices run on no money, care starts to suffer. It shouldn't be a free for all by any means, but there should be enough profit for things to run cleanly and efficiently. That's why so many doctors are bailing out of providing for Medicare patients. Their reimbursement has been cut steeply and overhead costs continue to rise. And this segment of the population NEEDS a lot of care, their cases are complex and complicated. And now I'm going to get off my soapbox......Sorry.
