Although the Hospital Price Transparency Rule – which requires hospitals to make public a comprehensive list of charges for items and services – has been in effect for almost two years, the Congressional House Committee on Energy and Commerce advises that hundreds of warning letters and requests for civil monetary penalties to hospitals that are still not fully compliant have been issued by CMS. In this Client Alert, our partner John W. Kaveney reports that the House Committee recently asked the Government Accountability Office (GAO) to take action to address this lack of compliance, and suggests that now is the time for hospitals to review their compliance and consult with legal counsel and other advisors to ensure that the legal requirements of the rule have been fully met in order to avoid significant financial ramifications.
