Connecticut DSS selected Sandata Technologies as the state EVV aggregator. The model is open: providers may use an approved alternate EVV system, but all visit data must be transmitted to the Sandata aggregator before claims are adjudicated. Telephonic verification (TVV) is supported as a backup alongside mobile and fixed visit verification methods. Home health care services came under mandatory EVV compliance January 1, 2024; DSS hardened enforcement July 1, 2024, denying claims without a matching Sandata EVV record.
What is EVV?
Electronic Visit Verification is the federal requirement (under the 21st Century Cures Act §12006) that personal-care and home-health visits paid by Medicaid be electronically captured at the point of care — who provided the service, who received it, where, when it started, and when it ended. CMS pushed enforcement to the states, which is why the day-to-day experience varies so much.
What "open model — choose any compliant vendor" means in Connecticut
Providers may use the state-provided aggregator at no cost OR any third-party EVV system that meets the state's technical specification (often called "AltEVV"). Either way, visit data must reach the state in the required format.
How does Caregiver Scheduling integrate?
Caregiver Scheduling captures the six required EVV data points on every visit (caregiver, recipient, start time, end time, location, service type) with GPS-stamped clock-in and clock-out, and telephonic backup for caregivers without a smartphone. In open-model states, our visits are EVV-compliant on their own. In mandated-aggregator states, we forward verified visits to the state system on a nightly schedule so payroll and Medicaid billing stay in sync without double-entry.
