South Dakota selected Therap as its state-mandated EVV vendor and data aggregator under the 21st Century Cures Act. Providers must use Therap; use of an alternative EVV system requires prior written approval from DHS, and the provider must upload EVV data to the state system. Therap includes IVR telephonic backup, though GPS/mobile app is the preferred verification method. CMS issued a good faith effort approval letter confirming SD's EVV compliance posture.
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 "state-mandated aggregator" means in South Dakota
Every Medicaid-billing provider in this state must use the contracted aggregator. Visits captured in any other system have to be forwarded to the state aggregator before they can be billed.
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.
