"Hospitals were more likely to make their charge data available and to offer a shoppable services tool than to post negotiated rates or cash prices.

The bottom line: "Compliance could be limited because the penalties for noncompliance are minimal (maximum $300 per day) and the costs of disclosure potentially great," the study's authors write."

The penalty for not complying needs to be waaaay higher than $300/day for hospitals to start complying.
