Prices Paid to Hospitals by Private Health Plans: Findings from Round 5.1 of an Employer-Led Transparency Initiative.

Because employer-sponsored spending comes from employee wages and benefits, employers have a fiduciary responsibility to administer benefits in the interest of participants. The lack of transparency of prices in the health care market limits employers' ability to knowledgeably develop or implement benefit design decisions. This study uses 2020-2022 medical claims data from a large population of privately insured individuals, including hospitals and other facilities from across the United States, to allow an easy comparison of hospital prices. An important innovation of this study is that hospitals and (hospitals under joint ownership) are identified by name, which is usually not allowed under data use agreements.
