EVV compliance and EVV billing are not the same thing.
Verifying a visit electronically is one job. Getting that verified data onto a payable claim is a different job. Revenue is lost in the gap between the two, and the gap is invisible on any single vendor screen.
What EVV captures, and where billing sits on top
Federal EVV under the 21st Century Cures Act records six data points for every personal-care visit: service type, recipient, date of service, location, individual providing the service, and the begin and end times.
The state aggregator is the clearinghouse that has to accept the visit before a payer will treat it as verified. A transmission failure at the aggregator leaves no record even when the EMR screen shows the visit as complete. The payer finds no matching visit on file and denies the claim, and the operations team sees a compliant visit on their side that is impossible to reconcile against the denial.
The four EVV billing gaps
Transmission failures between the EMR and the state aggregator. The most common and the hardest to see, because the EMR looks correct. Catch them by comparing the EMR completed-visit log against the aggregator received-records report before building claims, not after denials come back.
Location and timestamp flags the EMR does not surface. A visit outside the approved geofence, a check-in and check-out that round to the same minute, or a shift that overlaps another caregiver on the same member. The aggregator sees it; the scheduling screen does not.
Paper-backup visits never entered into the electronic record. A phone or paper backup is compliant only if it is reconciled into EVV within the payer's stated window. Left in a stack, it ages into an unbillable visit.
Payer-specific format and window rules layered on top of the state standard. A managed-care plan may require the EVV reference on the claim in a specific loop and segment, or may reject visits transmitted outside a defined window even when the state accepted them.
What to do about it
Run EVV exception reports before each billing cycle, not at claim time. Clear paper backups within a day or two, while the caregiver and member are still fresh on the visit. Document each payer's specific EVV requirements in one place your billers can actually reach. Track EVV denial rate by payer as an operational metric, because a rising rate on one plan is a contract or interface issue, not a caregiver behavior issue.
Where it fits
EVV billing gaps sit alongside unbilled hours, lapsed authorizations, and rate mismatches as one of the four categories that account for most recoverable margin in a home-care agency. Fixing it does not require a new EVV system. It requires reading the aggregator's output against the EMR's output before the claim goes out.
Plain answers, on the record.
Collect is money you never captured. Cover is money a payer can still take back.
Reeve reports the two separately and never adds them together, because only one of them is yours to go and get. The Margin Review reads both on your own export and costs nothing.
One pass over your own export, in your browser. The findings are yours to keep, with no obligation.
The recovery lane. Care you delivered and never billed, units short of what was authorized, lines paid under the published rate.
Everything in Collect, plus the exposure lane. Retired codes, authorizations at the end of their period, care delivered past what was approved.
