In compliance with the Transparency in Coverage Act, NASCO is making machine readable files (MRFs) that contain the negotiated rates for in-network providers and allowed amounts for out-of-network providers publicly available. These files follow the Centers for Medicare & Medicaid Services (CMS) defined layout and are in the CMS approved format (JSON) and are not meant for a consumer-friendly search of rates, benefits, or cost sharing.
