CMS to Host GADCS Office Hours on May 18, 2023

CMS header
Dear Ground Ambulance Providers and Suppliers,

Beginning in 2023, ground ambulance organizations selected in Year 1 and Year 2 are required to report cost, utilization, revenue, and other information to CMS within 5 months after your data collection period ends.  Selected ground ambulance organizations in Year 1 and Year 2 that reported a data collection period of January 1, 2022 – December 31, 2022 have a 5-month data reporting period after your data collection periods ends, that is January 1, 2023 – May 31, 2023, to report data. If you haven’t already, you should report your continuous 12-month data collection period to the GADCS portal. Please refer to this document for more information on how to access the system:  Organizations that fail to report may be subject to a 10 percent payment reduction.

Ground ambulance organizations selected in Year 3 and Year 4 will begin collecting data in 2023 and reporting data beginning in 2024. Selected ground ambulance organizations in Year 3 and Year 4 should have received a notification letter from your Medicare Administrative Contractor (MAC) about this requirement. Notifications were sent to the contact address in the Medicare Provider Enrollment, Chain, and Ownership System (PECOS) enrollment record linked to each selected NPI.  You are required to report your organization’s initial data requirement (start date of your data collection period and contact information).  If you haven’t already reported your organization’s initial data requirements,  you should provide the information at this website:
