CHA is reminding members that hospitals have until May 26 to verify their data and submit correction requests with supporting documentation to both the Centers for Medicare & Medicaid Services (CMS) and their Medicare Administrative Contractor (MAC) to: 

  • Correct errors due to CMS or MAC mishandling of the “final” wage data posted in the April 28, 2023, public use file

If a hospital is unable to submit an appeal using MEARIS, the hospital may submit it via email to
