MN DHS Service Agreements and Reassessments: How Authorized Hours Affect EVV Billing

An EVV system will happily verify a visit that was never authorized to happen. Electronic Visit Verification confirms the six federal data points: who, what, when, where, and the start and end time. It doesn’t check that visit against a client’s current service agreement, because that isn’t what EVV is built to do. That gap, between “the visit was electronically verified” and “the visit was authorized to be billed,” is where a surprising number of clean-looking claims get denied.

What a Service Agreement Actually Authorizes

Every Minnesota Medicaid waiver client (PCA, CFSS, CADI, BI, or EW) has a service agreement tied to their individual assessment, spelling out which services are authorized, at what frequency, and for how many units or hours over a defined period. This document, not the EVV system, is the actual source of truth for what’s billable. A caregiver can clock in and out perfectly, with clean GPS and a complete record on both ends, for a visit that exceeds the client’s authorized hours for that week, and EVV will still show a fully verified visit. Verification and authorization are two different questions, answered by two different systems, and conflating them is one of the more common blind spots for agencies newer to Medicaid waiver billing.

Where Authorized Hours Come From

Authorization originates with the client’s case manager (a county or tribal social worker, or a managed care organization care coordinator, depending on the client’s specific program), based on a standardized assessment of the client’s needs. That assessment sets a total authorized amount, typically expressed as units or hours per week or per month, which the agency then has to schedule caregivers against. The agency doesn’t set this number and generally can’t appeal it directly; only the client (or their representative) can request a reassessment if their needs have changed and the current authorization no longer reflects reality.

This matters operationally because the authorization a scheduler is working against today may already be stale. Needs change, but the paperwork updating the authorized amount doesn’t always keep pace.

The Reassessment Cycle and Why Timing Creates Risk

Waiver assessments are generally revisited on a recurring cycle, most commonly annually, though a significant change in condition can trigger an earlier reassessment outside the normal schedule. The risk window sits at the boundary between cycles. A few patterns show up repeatedly:

• The old authorization lapses before the new one is finalized. Reassessments don’t always land exactly on schedule, and a caregiver may keep showing up for previously-authorized hours during a gap where, technically, no current authorization exists.
• A client’s condition changes mid-cycle, and hours get added informally (a family calls the agency asking for more visits) before the case manager has processed a formal update to the service agreement.
• The agency’s scheduling system and the case manager’s authorization record drift out of sync, particularly when changes are communicated verbally or by a single email rather than through a formal, trackable update.

None of these show up as an EVV exception. The visit clocks in and out cleanly. The problem only surfaces later, when the claim is submitted against units that were never actually authorized, and gets denied or flagged for review, sometimes weeks after the visits were delivered and the caregiver was already paid.

What Happens When a Visit Exceeds Authorized Hours

A visit delivered outside the authorized amount doesn’t retroactively become authorized just because it happened and was documented well. Practically, agencies end up in one of three positions: the claim gets denied outright, the claim gets paid and then recouped later during an audit, or the agency absorbs the cost of an unbillable visit that already happened, caregiver hours already paid, revenue not recovered. The third outcome is the one that quietly erodes margin, because it rarely triggers a formal audit finding; it just shows up as a service that got delivered and never should have been scheduled against that client’s remaining balance.

Keeping Caregiver Schedules Aligned With Authorization

The practical fix isn’t a better EVV app; it’s a scheduling process that treats the current authorized balance as a hard constraint, not a background assumption. A few habits separate agencies that manage this well from ones that discover the gap at claim submission:

• Track remaining authorized units per client, not just the total authorization, so a scheduler can see how much balance is left before adding a shift, not just what the original authorization said months ago.
• Flag clients approaching their reassessment date far enough in advance that a lapse in authorization doesn’t sneak up on the office.
• Treat a family’s verbal request for more visits as a scheduling hold, not an approval, until the case manager has issued a documented update to the service agreement.
• Reconcile scheduled hours against the authorization on a fixed cadence (weekly is common), rather than discovering a mismatch only when a claim bounces.

None of this is EVV’s job to catch, and it’s worth being direct about that: a compliance rate can look perfect while an agency is quietly scheduling against an authorization that expired two weeks ago. We cover the broader shape of what EVV does and doesn’t catch in our Minnesota EVV requirements guide; authorization tracking is the layer that sits above it.

Where This Intersects With Waiver Type

Authorization mechanics vary somewhat by waiver. PCA assessments typically authorize a set number of hours per week based on a standardized needs assessment tool. CFSS, CADI, BI, and EW waiver services can authorize a broader mix of service types within an individual budget, which means the “remaining balance” a scheduler needs to track isn’t always a simple hours figure; it can be a dollar or unit budget shared across several different services. We walk through how the waivers differ structurally in our PCA, CFSS, CADI, BI, and EW waiver guide, which is worth reading alongside this one if your agency serves clients across more than one waiver type.

A Concrete Example

Say a client is authorized for 20 hours per week of PCA services, and a caregiver has been consistently scheduled for that full amount for months. The client’s annual reassessment comes due, and their needs assessment score comes back lower than the prior year, dropping the new authorization to 16 hours per week. If the office doesn’t catch that change before the next scheduling cycle, the caregiver keeps showing up for the same 20-hour pattern out of habit. EVV verifies every one of those visits cleanly: correct caregiver, correct client, correct GPS, correct clock-in and clock-out. None of that changes the fact that four hours a week are now unauthorized, and a claim submitted against the old 20-hour figure will eventually get flagged when it’s reconciled against the client’s current service agreement on file with DHS. The caregiver worked those hours and expects to be paid for them; the agency is the one left absorbing a service that was delivered but was never billable.

The inverse happens too, and it’s worth watching for: a reassessment that increases authorized hours doesn’t help an agency that’s still scheduling against the old, lower number, simply because nobody updated the schedule to reflect it. That’s a smaller compliance risk, but it’s still lost revenue sitting on the table for no reason other than a scheduling update that didn’t happen.

The Bottom Line

EVV answers “did this visit happen, verifiably.” It was never designed to answer “was this visit authorized to be billed,” and treating a clean compliance rate as proof that scheduling is also clean is where agencies get surprised at claim submission. The service agreement, not the EVV export, is the actual ceiling on what’s billable, and the agencies that avoid recoupment surprises are the ones tracking remaining authorized balance as closely as they track clock-ins.
