No offense to the Show HN tool you are talking about, (I applaud anyone building anything) but it wasn't nearly as sophisticated as people think it was. It was just a pretty web app put on top of a DB loaded with data from a spreadsheet that was released by CMS.gov (Center for Medicare/Medicaid Studies) which is a breakdown for all of the major hospitals in the country, priced out by procedure code. It's a very cool dataset, and I recommend checking it out. Its also useless for anything other than stuff done in hospitals.
