> Force hospitals to expose API's with transparent pricing.

Unless you're uninsured (which is a whole separate clusterfuck), the hospitals aren't the ones who decide how much you pay for any service - the insurance companies are. The sticker price that hospitals charge is almost meaningless and is intentionally high because it's used as the starting point for negotiations, which always bring the price down (never up). There isn't any expectation that any insurer is actually going to pay the billed amount as-is.
