I read a passage, the words in this part are not difficult, but I really can't catch the real meaing. So could you help me in rewriting the sentence in blue in short sentences. If possible, could you tell me what's the meaning of the writer.

Anderson knows how the health care financing system works — because 25 years ago, he helped write the Medicare rules that, to this day, form the basis for what the government and insurance companies will pay hospitals. He has testified as an expert witness in some lawsuits over hospital charges.

And since hospitals keep their price list — known as a "charge master" — largely secret, there's no way to compare one hospital’s prices to another.
"That information isn’t available to you. In the hospital sector, you can't do any comparative shopping. Because you can't do comparative shopping, the hospital has no reason to control prices," Anderson explains.

Now the hospital industry is feeling the pressure that KB Forbes and other advocates for the uninsured have focused on hospital billing practices.

"Are there some examples out there that somebody can find of a hospital who’s not doing everything they possibly can? I’m sure you have. But those hospitals need to do it better."  Carmela Coyle is the senior vice president for policy for the American Hospital Association. She acknowledges the problem, but insists hospitals can’t solve it alone.

"We’ve got to find a way to provide health insurance coverage for everybody in this country," Coyle says.

"The problem we’re talking about here is the difference between what most hospitals charge for people who are uninsured, and what they charge for the insurance companies. And let’s cut to the chase: Do you agree or disagree that that is the situation?" Rather asks.

Thanks for your help!!!!!!!!!!!!!!!!!!!!!!!
