Is the eligibility information available through eServices real time?

Published 03/29/2022

eServices uses the Centers for Medicare & Medicaid Services's (CMS's) HIPAA Eligibility Transaction System (HETS) 270/271 system, as required by the CMS, for all eligibility inquiries. Although eServices pulls data from HETS in real time, the data available in the HETS 270/271 system is only updated at certain times. CMS currently pulls the updated data Tuesday through Saturday during the hours of 6 p.m. and 8 p.m. This data is then uploaded into HETS during the hours of 9 p.m. to 6 a.m. As soon as updated data is available in the HETS 270/271 system, users will be able to view it in eServices.
