If price transparency and quality comparison were made easily accessible, and one could actually choose options regardless of considerations like "in-network," then it would be entirely conceivable that the majority of medical procedures would involve price shopping.

And such shopping around based on price and quality would improve things even for those who do not price shop. Feeling the pressure of market discipline would force providers to compete on quality and price.

There are sites that try to be like yelp for healthcare, but you ultimately don't have any price transparency, not every doctor is listed, and you have to navigate a maze of insurance categories. In a saner world, we would have better transparency in healthcare than pizza delivery.
