The Transparency in Coverage rules requires insurance carriers (for fully-insured health plans) and employers (for self-insured plans) to post information about the cost to participants, beneficiaries, and enrollees for in-network and out-of-network healthcare services through machine-readable files (MRF) on a public website. This information 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 access and analyze data more easily.
