You're talking about something outside of healthcare charging different prices to people based on which insurance they have and said practice is legal? I've never heard of such a thing. You're not referring to the common practice of bill inflation are you? For example, a tree falls onto your house and the damage is covered by insurance but the contractor knows insurance is paying for it so he jacks up the price once he finds out what you are getting from the insurance company (they tend to ask so that they can "plan" accordingly to stay within budget, but really they just want to make sure to capture the entire insurance check). This is 100% illegal but very hard to prove, hence it goes largely unenforced. With healthcare it's well-documented but still unenforced. If you are referring to something else I would be very interested to know what else operates in such a manner.
