Under the Transparency in Coverage Rule, issued in 2020 by the U.S. Department of Health & Human Services, U.S. Department of Labor and U.S. Department of the Treasury, health plans and health insurance issuers must provide access to two separate Machine-Readable Files (MRF). This link leads to the machine-readable files that are made available in response to the federal Transparency in Coverage Rule and includes negotiated service rates and out-of-network allowed amounts between health plans and healthcare providers. The machine readable files are formatted to allow researchers, regulators, and application developers to more easily access and analyze data.
