Validation
Every visit is automatically validated against 19 heuristic compliance checks and an AI-powered secondary review. Catch issues before they become rejected claims.
Try EVV in Demo19 Heuristic Compliance Checks
Every visit is automatically scanned against all 19 checks the moment a caregiver clocks out. Failed checks flag the visit for admin review with the specific issue code and a human-readable description.
NO_GPS_DATAHighNo GPS coordinates were captured at clock-in or clock-out.
GPS_OUTSIDE_GEOFENCEHighCaregiver GPS location is outside the patient's configured geofence radius.
DURATION_MISMATCHMediumActual visit duration differs from scheduled duration beyond the allowed threshold.
UNREALISTIC_DURATIONHighVisit duration is implausibly long (e.g., over 16 hours) or excessively short.
NO_CAREGIVER_SIGNATUREHighCaregiver did not provide their electronic signature at clock-out.
NO_PATIENT_SIGNATUREHighPatient or designee signature was not captured when required by state.
NO_MEDICAID_IDHighPatient is missing a Medicaid ID required for Medicaid-funded visits.
NO_SERVICE_CODEHighNo service/procedure code is assigned to the visit.
NO_AUTH_NUMBERMediumVisit requires a prior authorization number but none is on file.
AUTH_VISITS_EXHAUSTEDHighThe patient's authorized visit count has been fully used.
ZERO_DURATIONHighClock-in and clock-out timestamps are identical, resulting in zero duration.
FUTURE_TIMESTAMPHighClock-in or clock-out timestamp is in the future relative to server time.
CAREGIVER_MISSING_CREDENTIALSMediumCaregiver is missing required certifications or credentials for the service type.
NO_MEMBER_VERIFICATIONHighNo member verification method (signature, PIN, or voice) was completed.
OVERLAPPING_VISITSHighThis visit overlaps in time with another visit by the same caregiver.
NO_EXCEPTION_CODEMediumVisit has a flagged issue but no exception code was provided.
NO_REASON_CODEMediumVisit has an exception code but no reason code explaining the exception.
NO_TASK_DOCUMENTATIONMediumNo tasks were documented for the visit from the patient's care plan.
NO_GPS_CONSENTHighCaregiver has not granted GPS permission on their mobile device.
AI-Powered Secondary Validation
After the 19 heuristic checks run, AveeCare's AI engine performs a secondary analysis that catches patterns and anomalies that rule-based checks miss. Each AI review produces a confidence score indicating how likely the visit data is to be compliant.
What the AI looks for
- Unusual patterns in clock-in/out times across visits
- Suspicious GPS coordinate sequences (e.g., identical coordinates across different patients)
- Task documentation inconsistencies relative to care plan
- Signature similarity analysis for fraud detection
- Historical comparison against the caregiver's typical visit patterns
- Cross-visit anomaly detection (e.g., impossible travel times between patients)

Visit Status Lifecycle
Every EVV visit moves through a clear lifecycle. Each status is color-coded across the platform for quick visual scanning, and transitions are logged for full auditability.
Visit has been clocked out but not yet run through validation checks.
Visit passed all 19 compliance checks and AI validation. Ready for export.
One or more compliance checks failed. Requires admin review before export.
Admin reviewed and approved despite flagged issues. Override reason documented.
Visit data has been exported to the state aggregator in the selected format.
Admin Override & Audit Trail
Override Process
- Admin reviews the specific failed compliance checks
- Selects an override reason from predefined categories
- Provides a written justification for the override
- Visit status changes from Flagged to Overridden
- Overridden visits are eligible for export
Audit Trail Records
- Who performed the override (admin username)
- When the override occurred (timestamp)
- Which checks were overridden
- The override reason category selected
- The written justification provided
- Previous visit status before override
All EVV features included at $6/client/month.
No per-visit charges, no add-on fees, no long-term contracts.
