Electronic Visit Verification

What is Electronic Visit Verification?

EVV is a computer-based system that electronically documents and verifies service delivery information, such as date, time, service type and location, for certain Medicaid service visits.

21st Century Cures Act Updates

To comply with federal law, HHSC is implementing the federal 21st Century Cures Act (Section 12006) in the following two phases:

  • Effective Jan. 1, 2021, EVV is required for Medicaid personal care services.
  • Effective Jan. 1, 2023, EVV will be required for Medicaid home health care services.
    • Note: Federal law allows states to request a one-year extension to Jan. 1, 2024.

States that do not implement EVV will receive reduced federal Medicaid funding.

Visit the 21st Cures Act webpage for additional information.


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.

Visit Maintenance Unlock Request

A Visit Maintenance Unlock Request allows a program provider, FMSA and CDS employer the opportunity to correct data element(s) on an EVV visit transaction(s) after the visit maintenance time frame has expired.

Program providers, FMSAs and CDS employers must follow the instructions on the Visit Maintenance Unlock Request (Excel) spreadsheet. Requests that are not sent securely could result in a Health Insurance Portability and Accountability Act (HIPAA) violation and the payer will deny the request.
