HHSC is working in collaboration with MCOs, MEDsys and DataLogic to transition all providers before the MEDsys contract ends on Nov. 6, 2018.

All providers currently using the MEDsys VinCENT EVV system must complete transition to the DataLogic Vesta EVV system on or before Sept. 30, 2018. The 120-day vendor transfer policy has been waived.

Providers who do not transition to the Vesta EVV system on or before Sept. 30, 2018 may be unable to record visits for transmission to payers. Claims submitted without EVV visits may be denied, recouped or both. Providers should promptly begin the transition process by completing the actions below.


  • 1.Initiate the transition process with DataLogic. Providers currently using MEDsys must complete the Vesta EVV Agency Information form.
  • 2.Submit the form on or before July 31, 2018 to the email or fax number detailed in the form.
  • 3.DataLogic will contact the provider agency representative to begin the transition.

The MEDsys-issued small alternative devices cannot be transferred for use in the DataLogic system. Providers must indicate the number of SADs needed for delivery from DataLogic during the transition initiation process. Providers may choose to participate in the GPS Mobile Application pilot as an alternative to replacing all SADs.

Additional transition information and Vesta training opportunities are located on the Vesta website.
