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 and enforced beginning 7/1/22, health plans (which include clients who
sponsor employee benefit plans) and health insurance issuers must publish two MRFs:

• In Network: Negotiated rates for all covered items and services between the plan or
  issuer and in-network providers

• Out of Network: Allowed amount paid to, and billed charges from, out-of-network
  providers for all covered services within a 90-day period

The MRFs can be accessed with the below link: (Link available July 1st, 2022)

The above 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. Cigna will update the files each
month and the link will remain constant and always access the most up-to-date files.
