Medicare's Cool Simple Price Lookup Feature - Hospital, ASC, Physician, Etc

You can find APC/ASC prices with a lot of legwork via the CMS Excel files for these services.

CMS gives you a one stop look-up site (the copays are $0 here because it's a preventive service).  There's a button to click to expand the initial display so that it gives you CMS payments and Physician Services payments as well.
