Electronic Visit Verification — EVV — is a system that independently confirms that a home care visit took place, at the right location, at the right time, with the right caregiver. It was originally designed for the US Medicaid system, but the underlying compliance requirement is spreading to publicly funded home care programs across Canada, and the operational discipline it demands is relevant to every agency regardless of funding source.

For agencies that are still managing visit documentation through paper timesheets, caregiver self-reporting, or coordinator-recorded phone check-ins, EVV readiness requires a meaningful operational change. For agencies already using digital visit management tools, it primarily requires ensuring the right data is being captured and stored correctly.

What EVV actually is and isn't {#what-evv-is}

EVV is a documentation standard, not a surveillance system. The core purpose is to create an independently verifiable record that a specific caregiver provided a specific service at a specific location during a specific time window. The record cannot be manually backdated or altered after the fact by either the caregiver or the agency.

What EVV is not:

• A real-time tracking system that monitors caregivers throughout a visit
• A tool for watching caregivers' every movement
• A replacement for supervisory visits or quality assurance

The concern that EVV is intrusive is understandable but generally misplaced when the system is implemented correctly. Caregivers check in at the start of a visit and check out at the end. The system records the time and GPS location of those two events. What happens in between remains the caregiver's professional judgment.

The six core data elements {#what-to-capture}

EVV-compliant records must document:

1. Type of service: what care was provided (personal care, companionship, skilled nursing, etc.)
2. Service recipient: who the client is — name and identifier
3. Date: the calendar date of the visit
4. Location: where the service was provided — typically the client's home address, with GPS coordinates as independent verification
5. Caregiver identity: which caregiver provided the service
6. Start and end time: when the visit began and when it ended, captured by the system (not manually entered)

Any documentation system that captures all six elements via digital time-stamp at the point of care meets the core EVV requirement. Systems that rely on self-reported times, handwritten notes, or coordinator data entry after the fact generally do not.

GPS verification in practice {#gps}

GPS check-in and check-out is the most reliable way to satisfy the location element of EVV. When a caregiver opens a visit log on their phone and checks in, the system records the GPS coordinates of their device at that moment.

Practical realities of GPS-based EVV:

Tolerance zones: most EVV specifications accept check-ins within 200–400 metres of the client's service address. This accounts for GPS imprecision in urban environments (buildings, weather) and for caregivers who park nearby before walking to the door.

Rural and remote visits: GPS accuracy is generally better in rural environments than urban ones, but connectivity can be variable. EVV systems should allow offline check-in with queued transmission once connectivity is restored. Compliance reviewers generally accept brief connectivity gaps with supporting documentation.

Client privacy: GPS coordinates are recorded at check-in and check-out only — not throughout the visit. The location data belongs to the visit record, not to a continuous tracking file on the caregiver. Agencies should communicate this clearly to both caregivers and client families.

Geofencing: some EVV implementations add a geofence alert — a notification if a caregiver checks in or out from a location outside the expected service radius. This is a compliance tool, not a disciplinary one; the appropriate response to a geofence exception is to investigate the reason, not automatically penalise.

The Canadian regulatory landscape {#canadian-landscape}

Canada does not have a federal EVV mandate equivalent to the US 21st Century Cures Act. Home care is provincially regulated, and requirements vary considerably.

Ontario: the Home and Community Care Support Services system — which manages publicly funded home care through Ontario Health atHome — increasingly expects digital visit records that can be audited on request. Agencies providing services under OHIP-funded contracts are expected to maintain visit documentation that includes verifiable timestamps and service records.

British Columbia: Community Health Services delivered through health authorities are subject to documentation standards that align with EVV principles. GPS verification is becoming a standard expectation for new agency contracts.

Alberta: AHS-funded home care contracts include auditing provisions that require agencies to produce visit records with caregiver identity, service time, and location on request.

Private-pay across all provinces: EVV is not regulated for private-pay services, but agencies that maintain EVV-standard records have a significant competitive and liability advantage. In billing disputes — "we were not there that long" or "that service was not performed" — a timestamped, GPS-verified visit record is conclusive. An invoice supported only by a caregiver's self-reported timesheet is not.

Building EVV compliance into your operations {#building-compliance}

EVV compliance is an operational habit, not a technology project. The technology makes it possible; the training and workflow embed it.

Caregiver onboarding: every caregiver must understand why check-in and check-out are required and how to do it on their device. Agencies that present EVV as an administrative requirement get lower adoption than agencies that explain the purpose — protecting caregivers from false billing complaints, documenting their work accurately, and ensuring they are paid for every minute they work.

Exception handling: no system will have 100% clean records. Caregivers will forget to check in, phones will die, apps will crash. Your process must include a documented exception workflow — how a missed check-in is resolved, by whom, and what supporting evidence is required. A manual override with documented justification is EVV-compliant; an undocumented manual override is a red flag.

Supervisor review: someone at the agency should review EVV exception rates regularly. An individual caregiver with consistently high exception rates needs retraining. A systematic pattern of exceptions on the same client or the same shift suggests a scheduling or workflow problem.

Data retention: EVV records must be retained for the period required by your funder and by provincial health information legislation. This is typically 7–10 years. Ensure your records are stored in a way that supports retrieval and export for audit purposes.

Audit readiness {#audit-readiness}

An EVV audit — whether by a funder, an insurer, or in response to a complaint — will request records demonstrating that specific visits occurred as billed. Your ability to respond depends entirely on whether those records were captured correctly at the time.

What auditors examine:

• Gap between claimed time and EVV time: if your invoice claims a 4-hour visit and your EVV records show 2 hours 40 minutes, the difference will be questioned
• Check-in location vs. service address: records where the check-in GPS coordinates do not correspond to the client's address require explanation
• Pattern analysis: auditors look for patterns — caregivers who consistently check in exactly on the hour, visit durations that cluster at round numbers, or check-ins from locations inconsistent with the caregiver's known geography
• Exception documentation: every manual override or corrected record will be examined; clean exception documentation demonstrates good faith; absent documentation suggests manipulation

The agencies that pass audits without stress are not the ones who scramble to assemble records when a request arrives. They are the ones for whom EVV compliance is simply how visits work — every day, for every client.

EVV is not going away, and the agencies that build compliant systems now will not have to rebuild them under regulatory pressure later. The operational benefits — accurate billing, protected caregivers, verifiable care records — exist regardless of whether your funder requires it. Build the habit before it becomes the requirement.
