Colorado operates a hybrid open-choice EVV model: providers may use the state-funded Sandata solution at no cost or procure an approved third-party Provider Choice System. All EVV data must ultimately be transmitted to Sandata (the state aggregator) to validate Medicaid billing. The state EVV solution includes three capture methods: mobile app, toll-free telephonic number (TVV, available 24/7, supports landlines and cell phones), and a provider web portal. As of March 2025, billing providers must submit EVV exemption documentation through the new Gainwell Provider Web Portal EVV Exemption Form.

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 Colorado

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.
