One aspect of CMS’ price transparency initiative has received a great deal of attention recently. Our updated guidelines now require hospitals to post a list of their current “standard charges” on the internet in a machine-readable format — meaning the data can not only be read electronically but can also be imported or read into other databases. Previously, CMS required hospitals to make their standard charges available in response to an inquiry, but too often this meant making the information available only in print or a PDF that couldn’t be aggregated with other data and that wasn’t broadly available.
