I think, but am not sure, the point they're trying to make is that hospitals and insurance companies can "charge" really high prices and then they can forgve those high prices in exchange for a tax break?

That's not at all how it works so they don't have any idea what they're talking about. This is like when people say businesses can "write it off on their taxes". Only people who don't know what that really means say it.
