A new report, the Accrued Minutes Visits reports, which shows Accrued Minutes Visit counts, has been released.
This specification is intended to document the requirements for using the Sandata Real Time Interface (part of the Open EVV Series of Interface) for receiving information from 3rd party EVV Vendors into the Sandata Aggregator. This interface is also referred to as the EVV Vendor Solutions Interface. An EVV Vendor Solutions Data Collection System will build one data pipe to the Aggregator and send synchronous data packages per defined provider agency.
This interface includes clients, employees, visits, and their associated calls as well as the ability to send data related to visit modifications.
On Wednesday, January 7, 2026, Missouri Department of Social Services (MO DSS) began the soft launch phase of the claims validation process. Review the announcement from MO DSS on Claims Validation here. There is no change in how you will submit claims, but you will begin to see which claims would be denied based on the visit data submitted to EVV Aggregator Solution (EAS). This is a great opportunity to prepare your staff and identify potential challenges now to prepare for the hard edits phase.
