This link leads to the machine-readable files that are made available in response to the federal Transparency in Coverage Rule and include negotiated service rates and out-of-network allowed amounts between health plans and health care providers. The machine-readable files are formatted to allow researchers, regulators and application developers to more easily access and analyze data. › Clients need only follow this process once to establish the link. Cigna will update the files each month, and this link will remain constant and always access the most up-to-date files.
