Electronic Visit Verification

What is Electronic Visit Verification?

Electronic Visit Verification is a computer-based system that verifies the occurrence of authorized personal attendant service visits by electronically documenting the precise time a service delivery visit begins and ends. Texas requires EVV for certain Medicaid funded home and community-based services provided through the Health and Human Service Commission and managed care organizations.

21st Century Cures Act Updates

The EVV practice period has been extended to Dec. 31 and the timeline has been updated on the HHSC EVV Cures Act webpage.

By Jan. 1, 2021, the Cures Act EVV Expansion will implement the Cures Act federal EVV requirement for Medicaid personal care services that are not currently required to use EVV by state law.


Compliance Oversight Reviews monitor program providers contracted with HHSC and managed care organizations on the use of an EVV system to electronically document authorized service delivery visits. Program providers will be reviewed on a regular basis to ensure they are following EVV policy.
