Beginning May 1, Medicare Part A providers can use MCReF to submit cost reports with fiscal years ending on or after December 31, 2017. You will have the option to electronically transmit your cost report through MCReF or mail or hand deliver it to your Medicare Administrative Contractor. Starting July 2, you must use MCReF if you choose electronic submission of your cost report.
Access to MCReF will be controlled by the CMS Enterprise Identity Management (EIDM) system. Security Officials (SOs) and Backup SOs registered in EIDM for access to the Provider Statistical and Reimbursement (PS&R) system will have access to MCReF through their existing account.
Providers that are not registered in EIDM as PS&R users must register and assign an SO for their organization.
