Is the eligibility information available through eServices real time?
eServices uses CMS's HETS 270/271 system, as required by 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 once daily in the mornings (ET). The HETS response is not updated during the day.
Providers should not resubmit the same transaction multiple times thought out the day expecting to receive different results. As soon as updated data is available in the HETS 270/271 system, providers will be able to view it in eServices. For more information on HETS, visit HIPAA Eligibility Transaction System (HETS) | CMS.
