Electronic Visit Verification (EVV) is a technology that confirms home health and personal care visits actually happened. It's federally mandated under the 21st Century Cures Act and required by every state Medicaid program.
If you run a home health or home care agency, EVV isn't optional -- it's the law. But the details of what EVV captures, how enforcement works, and what it means for your daily operations can be confusing. This guide breaks it all down.
What Is EVV?
EVV is an electronic system that verifies in-home service visits occurred as scheduled. Instead of relying on paper timesheets, EVV uses technology -- GPS, mobile apps, telephony -- to create a digital record of every visit.
When a clinician or caregiver arrives at a patient's home, the EVV system records who showed up, where they went, when they arrived, when they left, and what service they provided. That data is transmitted to the state's Medicaid system for verification. Before EVV, agencies self-reported visit data on paper with no independent confirmation. EVV closes that gap with an objective, timestamped record.
The Six Required Data Elements
Section 12006 of the 21st Century Cures Act specifies exactly six data points that every EVV system must capture for each visit:
| # | Data Element | What It Means |
|---|---|---|
| 1 | Type of service | What service was provided (skilled nursing, physical therapy, personal care, etc.) |
| 2 | Individual receiving the service | Which patient was seen |
| 3 | Individual providing the service | Which clinician or caregiver performed the visit |
| 4 | Date of service | The calendar date the visit occurred |
| 5 | Time of service | When the visit started and when it ended |
| 6 | Location of service | Where the visit took place, verified by GPS or other means |
That's it. The law doesn't prescribe how you capture this data -- only that you capture it. States have significant discretion in choosing the technology and implementation model, which is why the landscape varies so much.
Why EVV Exists: The 21st Century Cures Act
The 21st Century Cures Act was signed into law on December 13, 2016. While best known for accelerating drug approvals, Section 12006 addressed a long-standing problem in home-based care: fraud and accountability.
Home-based services are delivered in private homes with no direct supervision. Visits historically relied on the honor system, creating opportunities for fraud -- billing for visits that never happened, inflating hours, or documenting care that wasn't provided. Section 12006 required every state to implement EVV for:
- Medicaid personal care services (PCS) by January 1, 2020
- Medicaid home health care services (HHCS) by January 1, 2023
States that failed to meet these deadlines faced incremental FMAP reductions (the federal share of Medicaid funding) of up to 1 percentage point per year -- tens of millions of dollars for most states. The only exemption: states that demonstrated both a "good faith effort" toward compliance and "unavoidable delays."
How EVV Works in Practice
There are four common technologies used to capture EVV data. Most agencies use one or a combination:
GPS / Mobile App
The most common approach in 2026. The clinician opens a mobile app, taps to clock in at the patient's home, and taps to clock out when they leave. GPS captures the location automatically. No hardware installation required.
Telephony (IVR)
The clinician calls a toll-free number from the patient's landline when arriving and departing. Caller ID verifies the location. Still used in rural areas where cellular coverage is unreliable, but declining.
Fixed Visit Verification (FVV) Devices
A small device installed in the patient's home -- the clinician swipes an ID card or enters a code to log arrival and departure. Less common today due to hardware cost and maintenance.
Biometric Verification
Fingerprint or voice recognition to verify the caregiver's identity. Adds identity fraud prevention on top of location and time verification.
In practice, the mobile app model has won. It's cheaper, requires no hardware, works with devices clinicians already carry, and captures GPS coordinates with high accuracy. The workflow is simple: arrive, tap clock-in, provide care, capture patient signature, tap clock-out, move on.
Home Health vs Home Care: Different Rules
EVV applies to both home health and home care, but the rules differ because these are fundamentally different service types.
Home health involves skilled clinical services -- nursing, physical therapy, occupational therapy, speech therapy -- provided by licensed professionals under a physician's plan of care.
Home care (personal care services) involves non-clinical assistance with activities of daily living -- bathing, dressing, meal preparation -- provided by home health aides or personal care attendants. Primarily Medicaid-funded.
The Cures Act treated them on separate timelines because personal care services were historically more vulnerable to fraud:
| Service Type | EVV Deadline | Primary Payer |
|---|---|---|
| Personal care services (PCS) | January 1, 2020 | Medicaid |
| Home health care services (HHCS) | January 1, 2023 | Medicaid |
What about Medicare? Medicare doesn't currently mandate EVV, but many Medicare Advantage plans require it contractually. The practical advice: implement EVV for all visits regardless of payer. The direction of regulation is clear.
State-by-State Variation
While the federal mandate sets the floor, each state chose its own implementation model. This is the single biggest source of confusion for multi-state agencies.
Open Model (Most States)
The state provides a free EVV system (typically HHAeXchange or Sandata), but agencies can use their own compliant system instead. The catch: your system must integrate with the state's data aggregator. Alabama, Colorado, California, Minnesota, and Wisconsin use this approach.
Closed / Mandated Vendor Model
The state requires all agencies to use a specific EVV vendor. No alternatives. Connecticut (Sandata), Illinois (Santrax), Kansas (AuthentiCare), and Nevada (AuthentiCare) operate this way.
State-Built System
A handful of states built their own platforms. Maryland uses ISAS, Oregon uses eXPRS.
Provider Choice
Some states -- Idaho, New York, Virginia, Washington -- let agencies select and fund their own solution, as long as it meets compliance requirements.
What to Check in Your State
- Which aggregator must you submit data to?
- What verification methods are accepted? GPS only, or telephony too?
- What's the submission timeline? Real-time, daily, or batch?
- What's the compliance threshold? Most states now require 80-85% EVV accuracy.
- How do you handle exceptions? GPS failures and manual entries need a documented workflow.
As of 2026, enforcement has shifted from "get a system in place" to "prove you're using it." Texas has resumed strict usage reviews, with agencies below 80% compliance facing corrective action plans. Several states have moved from soft edits (paying claims despite EVV data errors) to hard edits (automatic claim denials for incomplete records).
What Happens If You Don't Comply
Non-compliance has real financial consequences at two levels.
At the state level, the Cures Act imposes FMAP reductions up to 1 percentage point per year on non-compliant states. This pressures states to enforce compliance aggressively with providers.
At the agency level, consequences vary by state but typically include:
- Claim denials -- visits without complete EVV data are rejected outright
- Payment recoupment -- states can demand repayment for previously paid claims lacking EVV documentation
- Corrective action plans -- agencies with low compliance rates are placed on formal improvement plans
- Contract termination -- persistent non-compliance can result in loss of Medicaid managed care contracts
- Audit exposure -- incomplete EVV data makes your agency a target for state and federal audits
The math is straightforward. If 15% of your Medicaid visits lack EVV data and your state has moved to hard edits, you're losing 15% of that revenue. For most agencies, that's existential.
Frequently Asked Questions
Does EVV apply to Medicare visits? Not yet. The Cures Act mandate applies only to Medicaid-funded services. However, many Medicare Advantage plans require EVV contractually, and CMS has signaled potential expansion. Most agencies implement EVV for all visits to keep workflows consistent.
What happens when GPS doesn't work? GPS can fail in basements, rural dead zones, and apartment buildings. Compliant systems allow manual location entry with a reason code. Document the address, note why GPS failed, and submit within your state's correction window.
Can patients refuse EVV? No -- it's a condition of Medicaid service delivery. The patient's role is minimal, usually just a signature on the clinician's device. If a patient can't sign, most states accept a caregiver signature with documentation.
Do I need a separate app for EVV? Not if your scheduling software has EVV built in. Standalone EVV apps create friction -- clinicians juggle two tools and data reconciliation becomes a burden. The best approach is a single platform where EVV is part of the normal visit workflow.
What's the difference between an EVV vendor and an aggregator? The vendor provides the technology clinicians use (the app, GPS, clock-in/out). The aggregator is the state's central system that collects EVV data from all agencies. In open model states, your vendor must integrate with the state's aggregator. In closed model states, vendor and aggregator are the same system.
