CMS Releases New GADCS Tip Sheet for Rural, Super Rural Services

The Centers for Medicare & Medicaid Services (CMS) released a new “Reporting for Rural and Super-Rural Organizations Tip Sheet” on February 16, 2024. This guide assists ground ambulance organizations in rural and super-rural areas to meet the Medicare Ground Ambulance Data Collection System (GADCS) requirements.

You can find all of their tip sheets, including those focused on allocation, governmental, and public safety organizations, on the CMS GADCS website.

Services selected as part of the Year 3 and Year 4 list are due to submit their 2023 data to CMS by May 31, 2024, or 5 months after the close of their fiscal year. The AAA offers various resources to help services collect, verify, and submit data on time and avoid penalties. For more information about our resources, including Amber, email
