Health News Today writes the Centers for Medicare & Medicaid Services (CMS) has started the process of searching for a company to help create a price comparison tool for consumers. It has released a sources sought notice to see if any companies have the expertise to perform such work. A formal request for proposals for the work could be released later depending on the responses the agency receives to the CMS query on what would be a transparency-focused web portal. Interested companies must respond by Sept. 24. The notice comes as the CMS is pushing hospitals to be more transparent about what they charge patients.
