Reminder for Part A Providers: Medicare Cost Report Submission

Attention Part A Providers: Your Medicare cost reports for the fiscal year ending December 31, 2024, are due to Noridian by May 31, 2025. Submit early to avoid issues.

Rejected reports are treated as unfiled cost reports. Late submissions or uncorrected rejections will result in withheld payments and a Demand Letter. More information on cost report due dates and requirements can be found on our Cost Reports page.

We encourage you to use the Medicare Cost Report e-Filing system (MCReF) for a streamlined, efficient submission process. MCReF is a free, CMS-authorized portal that allows you to electronically file 100% of your cost report package, including all supporting documentation, directly to your Medicare Administrative Contractor (MAC) for fiscal years ending on or after December 31, 2017

Benefits of Using MCReF:

  • Immediate Receipt Notification: MCReF provides instant confirmation that your cost report has been received, helping you avoid delays.
  • User-Friendly Interface: The system features a simple, straightforward interface with just one screen, making it easy to navigate.
  • Timesaving: By filing electronically, you eliminate the need to compile and mail physical paperwork or electronic media, saving you valuable time.
  • Secure Submission: MCReF ensures that your cost report and all supporting documents are securely transmitted to your MAC
  • Access to Documentation: Providers can access important documentation such as interim rate review (IRR), tentative settlement (TS), and final settlement letters.

For detailed instructions on using MCReF, you can refer to the MCReF User Manual. CMS also has a Medicare Cost Report Electronic Filing (MCReF) website with resources for MCReF webinars, presentations, how to request MCReF access, and frequently asked questions.
