Electronic Visit Verification (EVV)

What is EVV?

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

HHSC is implementing the federal 21st Century Cures Act (Section 12006).

The 21st Century Cures Act, or Cures Act, is a federal law that passed in 2016 requiring states to implement EVV for Medicaid personal care services and home health care services that require an in-home visit. States that do not implement EVV will receive reduced federal Medicaid funding.

  • Effective Jan. 1, 2021, EVV is required for Medicaid personal care services.
  • Effective Jan. 1, 2024, EVV is required for Medicaid home health care services.

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


HHSC and managed care organizations, the payers, conduct EVV compliance reviews to ensure program providers, Financial Management Services Agencies and Consumer Directed Services employers are in compliance with EVV requirements and policies.

Visit Maintenance Unlock Request

An EVV 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 EVV Visit Maintenance Unlock Request spreadsheets. Request emails must include a contact name, email address and phone number. 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.
