What is EVV (Electronic Visit Verification)?

The 21st Century Cures Act requires every EVV system to record:

• The type of service performed
• The individual receiving the service (the client)
• The individual providing the service (the caregiver)
• The date of the service
• The location where the service was delivered
• The time the service begins and ends

Congress passed the EVV mandate as part of the 21st Century Cures Act to reduce improper payments and fraud in Medicaid home and community-based services. By electronically confirming that a visit took place — at the right place, for the right client, by the right caregiver — states and payers gain accountability that paper timesheets could not provide. States that did not comply faced reductions in federal Medicaid funding.

• January 1, 2021 — EVV required for Medicaid Personal Care Services (PCS).
• January 1, 2023 — EVV required for Medicaid Home Health Care Services (HHCS).
• States implement EVV through an open, closed, or state-choice model, so exact vendor and data requirements vary by state.

In practice, a caregiver arrives at the client’s home and clocks in on a mobile app, which captures the time and GPS location. They deliver the scheduled services, then clock out at the end of the visit. The visit record — matched against the schedule and care plan — flows into billing, so claims are supported by verified visits. Exceptions (a missed clock-in, a location mismatch) are flagged for office staff to resolve before the claim goes out.

Tunzly includes EVV as part of the platform: caregivers clock in and out from the mobile app, visits are verified against the schedule, and an EVV dashboard surfaces exceptions to resolve before billing. Because scheduling, EVV and claims share the same data, a verified visit becomes a clean claim without re-entry.
