Missouri uses an open (provider-choice) EVV model under which personal care and home health care service providers select their own EVV vendor; all vendors must pass testing to interface with the state-designated aggregator, Sandata Technologies (contract CT210348001, effective April 1, 2021). Sandata operates the EVV Aggregator Solution (EAS) that collects and stores visit data from all approved third-party vendors. EVV compliance methods include mobile apps with GPS, telephony from a landline, fixed devices, and biometric recognition, confirming telephonic backup is permitted. MO HealthNet began a soft launch of claims validation on January 7, 2026, with a hard launch phase scheduled for April 1, 2026.
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 Missouri
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.
