What Is EVV? The Home Care Agency's Guide to Electronic Visit Verification

Electronic Visit Verification (EVV) has quietly become one of the most important operational requirements in home-based care. If your agency bills Medicaid for personal care services or home health services, EVV isn't optional — it's federal law. But the term still gets thrown around loosely, and every state seems to implement it a little differently.

This guide breaks down what EVV actually is, what it captures, how the state models compare, and what to look for in software that keeps your agency audit-ready.

What EVV Is (and Why It Exists)

EVV is a system that electronically records the details of a home or community-based visit at the moment it happens — not later, from memory or a paper timesheet. It was mandated by the 21st Century Cures Act, signed into law in 2016. Under the Cures Act, state Medicaid programs must require EVV for:

• Personal Care Services (PCS) — federally required since January 1, 2020
• Home Health Care Services (HHCS) — federally required since January 1, 2023

States that fail to implement EVV face reductions in their federal Medicaid matching funds, which is why every state has some form of EVV in place today.

The Six Data Elements EVV Must Capture

The Cures Act specifies six data points that every verified visit must record:

• Type of service performed (e.g., personal care, skilled nursing)
• Individual receiving the service (the client or member)
• Date of the service
• Location of service delivery
• Individual providing the service (the caregiver, aide, or clinician)
• Time the service begins and ends

That's the federal floor. Many states add requirements — task confirmation, client signature or voice verification, mileage capture — on top.

The State EVV Models

CMS gave states flexibility in how they implement EVV. In practice, states fall into four broad models:

• State-mandated single system. The state contracts with one EVV vendor, and every provider must use it. Predictable, but often clunky and inflexible.
• Provider choice (open vendor model). Providers can choose any EVV system that meets state data requirements and feeds an aggregator. This is the most common model today.
• MCO / managed-care choice. Each managed care organization selects its EVV system, so multi-payer agencies may have to work with several.
• Open model. The state accepts data from any compliant system, with minimal prescription of tools.

If you operate in multiple states — or serve multiple MCOs in one state — expect to interact with more than one EVV pathway.

Common Pitfalls Agencies Hit

Even with software in place, most EVV audit findings trace back to a handful of recurring problems:

• Manual entry and back-dated visits. These are red flags in any audit. Manual edits should be the exception, documented with a reason, and separately reported.
• GPS gaps. Rural areas, apartment buildings, and dead zones cause missing or inaccurate location data. Software should handle offline capture and reconcile when the device is back online.
• Timing mismatches. Check-in and check-out times that don't match the authorized visit window trigger denials.
• Missing signatures or task confirmations where the state or payer requires them.
• Data that doesn't reach the state aggregator. Passing state audits requires proof that visit data was successfully transmitted, not just captured in your system.

What to Look For in Modern EVV Software

A caregiver or clinician shouldn't need training to complete an EVV-compliant visit — the software should handle it. The essentials:

• Mobile check-in and check-out with GPS on both ends
• Offline capture with automatic sync when connectivity returns
• Digital client signature or approved alternative (voice, PIN, tap-to-confirm)
• Task confirmation aligned to the plan of care
• Automatic aggregator integration for every state and MCO you serve
• Real-time exception dashboards so office staff can fix issues before claims are submitted
• Full audit trail showing every edit, who made it, and why

Done right, EVV isn't a compliance burden — it's the layer that turns every visit into a clean, billable, defensible record.
