The CMS Transparency in Coverage Rule requires that health insurers eventually make available to the public detailed pricing information for all covered in-network services and procedures. By July 1, 2022, computer-readable files must be available to consumers, researchers, and third-party app developers. By 2023, plans must have online tools that let policyholders see their personalized out-of-pocket costs and the underlying prices for 500 shoppable covered items and services. And by 2024, these web tools must expand to include all covered items and services.
