EVV basics: electronic visit verification for new home care agencies

What EVV is

Electronic visit verification (EVV) is a way to record, electronically, that a home visit actually happened, and when, where, and by whom. Caregivers usually check in and out using a mobile app, a phone call from the client’s home, or a small device. The visit data then flows to a state or vendor system, which matches it against authorizations and claims.

If your agency will serve Medicaid clients receiving personal care or home health services, you should expect EVV to be part of daily operations. Private-pay clients may not require it, but some agencies use similar tools for everyone to keep processes consistent.

Why EVV exists: the federal requirement

The 21st Century Cures Act added an EVV requirement to the Medicaid statute. States that don’t require EVV for Medicaid personal care services and home health care services that need an in-home visit face a reduction in federal matching funds. The statute set start dates of January 1, 2020 for personal care services and January 1, 2023 for home health care services, with good-faith exemptions available in some cases. (Source: 42 U.S.C. §1396b(l), checked on 2026-09-25.)

That’s why EVV comes from your state: the federal law pushes states to require it, and each state chooses how.

The six data points federal law names

The statute defines an EVV system as one under which visits are electronically verified with respect to:

1. The type of service performed
2. The individual receiving the service
3. The date of the service
4. The location of service delivery
5. The individual providing the service
6. The time the service begins and ends

(Source: 42 U.S.C. §1396b(l)(5)(A), checked on 2026-09-25.)

Whatever system your state uses, it will be built to capture these six things. If you train your caregivers around those six items, most of the rest makes sense.

The statute also asks states to consult with providers so the system is “minimally burdensome,” to follow HIPAA privacy and security requirements, and to give the people who furnish services “the opportunity for training on the use of such system.” (Same source.)

How states set up EVV

States generally choose one of a few approaches, and your state Medicaid agency’s EVV page should say which model it uses:

• State-sponsored system. The state or its contractor provides one EVV system that all providers use, sometimes at no cost to the agency.
• Open model. The state provides a system but lets agencies use their own approved vendor, as long as the data feeds into the state’s aggregator.
• Managed care plan systems. Where HCBS is delivered through managed care, individual plans may have their own EVV rules or vendors.

Each approach affects your software choices and costs. Before you buy scheduling software, ask your state which EVV systems are approved and whether your software can integrate with the state’s aggregator.

What EVV changes in daily operations

For caregivers

• Every visit starts and ends with a check-in and check-out.
• Location capture (such as GPS or a client-home phone line) means caregivers must be at the client’s location when they check in and out.
• Missed or late check-ins create exceptions that office staff must fix.

For office staff

• Someone reviews visit exceptions daily, such as missing check-outs, wrong locations, or visits outside the authorized schedule.
• Manual corrections usually require a reason code and documentation, following your state’s EVV manual.
• Visit data must line up with service authorizations before claims go out.

For clients and families

• Clients may be asked to confirm visits or allow a device or phone call from the home.
• Explain EVV at intake so it doesn’t feel intrusive. It protects clients too, by documenting that they got the care they were authorized to receive.

How EVV connects to billing

In many states, claims for EVV-covered services are checked against EVV records before payment. If the visit data is missing, doesn’t match the authorization, or shows a different time or place, the claim may be denied or held, depending on how your state and payers handle mismatches. For a new agency with thin cash reserves, a steady trickle of EVV-related denials can hurt quickly. A daily habit of clearing exceptions is one of the most useful routines you can build.

A preparation checklist

1. Confirm which of your planned services require EVV under your state’s rules.
2. Find the state’s EVV page, provider manual, and training schedule.
3. Choose the state system or an approved vendor, and confirm how data reaches the state aggregator.
4. Write an EVV policy: how caregivers check in and out, what to do if the app or phone fails, and how corrections are approved.
5. Train caregivers during onboarding and check their first few visits.
6. Explain EVV to clients at intake and note any special situations, such as clients without a landline or visits in the community.
7. Assign one person to review exceptions every business day.
8. Reconcile EVV data with authorizations before each billing cycle.

Common pitfalls

• Buying software before confirming it works with your state’s EVV setup
• Letting caregivers “fix it later” on missed check-outs
• Not documenting the reason for manual edits
• Assuming private-pay processes will carry over to Medicaid billing unchanged
