CHIA collects annual hospital cost report for both acute care and non-acute care hospitals. The Massachusetts Hospital Cost Report leverages data already reported by hospitals to Medicare on the CMS 2552-10 filing, while still collecting data specific to Massachusetts hospitals.

This report is used by CHIA for regulatory, policy development, monitoring and informational purposes. Hospitals must submit their data in accordance with 957 CMR 9.00 and the filing requirements set out in the hospital cost report instructions which can be found in the link on the right of this page.

Starting with the FY2020 hospital cost report, acute hospitals are required to use the Hospital Supplemental Revenue Template (Excel) to report such income. Additional instructions to complete this template are available in the link on the right of this page.  Non-Acute hospitals will continue to use Tab 4 to report Supplemental Revenue. The template and instructions were updated for the FY2023 filing.
