EVV Audit Preparation Checklist for Home Care Agencies

An EVV audit is rarely a surprise. It’s usually the result of a compliance rate that’s been drifting for months before anyone noticed. Agencies tend to treat EVV compliance as a background system that either works or doesn’t, and only look closely at it once DHS asks a pointed question about a specific batch of claims. By then, the pattern that triggered the review has usually been running quietly for weeks. Here’s what to check before it becomes DHS’s problem to point out instead of yours.

What Gets Reviewed

• Overall EVV compliance rate. The percentage of visits verified electronically without manual correction. Minnesota expects agencies to stay around 80% or higher, and the number that matters isn’t just your agency-wide average: it’s the distribution underneath it. An agency sitting at 85% overall can still have a handful of caregivers or a specific waiver population dragging well below that, and averages hide that until someone goes looking.
• Exception patterns. A handful of missed clock-outs is normal: caregivers forget, phones die, signal drops in a basement apartment. A consistent pattern from the same caregivers or the same clients draws more scrutiny, because it suggests either a training gap, a genuine service-delivery problem, or in the worst case, documentation that doesn’t reflect what actually happened.
• GPS accuracy. Visits logged from locations inconsistent with the client’s address, repeated often enough, raise questions. One outlier is noise: a caregiver’s phone briefly losing signal near a building’s edge. A recurring offset from the same caregiver or the same address is a pattern DHS is trained to notice.
• Timeliness of manual corrections. When exceptions do happen, how quickly they get resolved and documented matters as much as the exception itself. A missed clock-out corrected the same day, with a clear note explaining why, reads very differently from a batch of corrections made the day before a billing deadline.
• Documentation alignment with the care plan. EVV data confirms a visit happened at a given time and place. It doesn’t, by itself, confirm the right services were delivered. Auditors cross-reference visit records against each client’s authorized service plan to check that what’s billed matches what’s approved. A mismatch here is a separate, and often more serious, finding than an EVV exception.
• Caregiver credentialing and training records. For PCA, CFSS, CADI, BI, and EW visits alike, DHS wants to see that the person who clocked in was actually authorized to deliver that service under Minnesota’s requirements at the time of the visit, not retroactively brought into compliance after the fact.

Three Things to Check Monthly

1. Run your exception report before DHS does. If your EVV tool has an exception manager, review it weekly, not just when a claim gets denied. Missing GPS and missed clock-outs are far easier to fix the day they happen, while the caregiver remembers the visit and can confirm what actually occurred, than three weeks later when it’s one line in a spreadsheet nobody can explain. Treat the exception queue the way you’d treat an inbox: something that gets to zero on a regular cadence, not something that accumulates until it’s unmanageable.

2. Spot-check caregiver clock-in consistency. A caregiver who frequently clocks in from outside the expected radius isn’t necessarily doing anything wrong. GPS drift near dense apartment buildings and rural addresses with imprecise geocoding are both common, mundane explanations. But know why before an auditor asks, and have that explanation documented rather than reconstructed under pressure. A five-minute monthly review of your highest-exception caregivers usually surfaces whether it’s a device issue, an address issue, or something that actually needs a conversation.

3. Confirm your service codes match your care plans. A visit billed under the wrong HCPCS code is a documentation problem waiting to surface, EVV-compliant or not. This is easy to overlook because EVV and billing can feel like separate systems even when they’re technically integrated, but an auditor reviewing a flagged visit will look at both together, and a mismatch between the two is a much harder finding to explain away than a missed clock-out.

4. Review your corrective action turnaround time. If your agency has ever been asked to explain an exception pattern, look at how long it took from the request to a documented resolution. A slow, scrambled response to a routine DHS inquiry is itself a signal: not necessarily of fraud, but of a process that isn’t built to withstand scrutiny. Fixing that turnaround time before you’re asked again is cheaper than fixing it under a deadline.

Common Exception Patterns and What They Usually Mean

Not every exception means the same thing, and knowing the difference saves time when you’re triaging a queue. A missed clock-out clustered around a single caregiver’s shift transitions often just means they’re going straight from one client to the next without a natural break to close out the app. That’s a training fix, not a compliance problem. GPS exceptions concentrated at one address, across multiple caregivers, usually point to a geocoding issue with that specific client’s location rather than caregiver behavior. Exceptions that spike on specific days of the week can indicate a scheduling gap: a substitute caregiver covering a shift who wasn’t properly onboarded to the app. And exceptions that don’t fit any of these patterns (inconsistent, spread across caregivers and clients with no obvious cause) are the ones worth the closest look, because they’re the hardest to explain with a routine answer.

Documentation That Actually Helps

If DHS does flag your agency for review, the strongest thing you can show is a clean, consistent trail: GPS-verified clock-in/out on the vast majority of visits, a documented process for resolving the exceptions that do occur, and evidence that corrections happened promptly rather than in a batch right before submission. Beyond the visit-level data, it helps to have a short written policy, even one page, describing how your agency handles exceptions: who reviews them, how often, and what the escalation path looks like when a pattern needs more than a one-line correction. Auditors aren’t just checking whether your numbers are clean; they’re checking whether your process is the kind that would keep them clean going forward.

What Happens If DHS Flags Your Agency

A review doesn’t automatically mean a penalty. In most cases, DHS will request an explanation for a specific pattern, whether that’s a cluster of exceptions, a compliance rate dip, or a mismatch between billed codes and care plans, and give your agency an opportunity to respond. Agencies that can produce a clear, documented answer quickly tend to close these out without further escalation. Agencies that can’t reconstruct what happened, or whose exception-handling process is inconsistent, are the ones who end up on a corrective action plan or, in more serious cases, subject to a broader audit of their billing history. The gap between those two outcomes is almost entirely about whether the documentation existed before the question was asked.

Building a Monthly Audit-Readiness Routine

None of this requires a dedicated compliance hire at most agency sizes. A workable routine looks like: a designated person (often an office manager or scheduling coordinator) reviews the exception report weekly, a monthly quick review of compliance rate by caregiver and by client, and a standing note of any pattern that needed more than a one-line fix. That’s it. The goal is making sure that if DHS ever does ask a question, the answer already exists instead of needing to be built from scratch under a deadline, not standing up a heavyweight audit function.

The Real Goal

Audit preparation is a byproduct of a clean EVV process running every day, not a once-a-year scramble. An exception manager that flags problems before export exists specifically so this checklist becomes unnecessary busywork instead of a fire drill. Agencies that treat EVV compliance as a daily habit rather than a quarterly cleanup consistently spend less total time on it, and have a much easier conversation whenever DHS does come asking.
