21st Century Cures Act Updates

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

  • Effective Jan. 1, 2021, EVV is required for Medicaid personal care services.
  • The Cures Act requires states to implement EVV for Medicaid home health care services by Jan. 1, 2023. HHSC will request a good faith effort exemption from the Centers for Medicare and Medicaid Services to extend this deadline by one year. HHSC plans to implement EVV for Medicaid HHCS on Jan. 1, 2024.

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

Visit the 21st Cures Act webpage for more information.


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.
