Transparency in Coverage Rule

The Transparency in Coverage Rule requires public disclosure of negotiated in-network provider rates and out-of-network allowed amount and bill charges for items and services covered by a health plan/policy.

PreferredOne is on track to provide the MRF files by the enforcement deadline of 7/1/2022. The third machine-readable file for drug pricing information has been deferred until further guidance is provided.

Go to and select Transparency in Coverage – Machine Readable Files. The live data will not be posted on the site until 7/1/2022.

The MRF files are not the cost comparison tool. Cost comparison is scheduled for 2023 for the 500 shoppable items, services and drugs in the final rule.

Contact your PreferredOne Representative if you have questions.
