Validation

Every visit is automatically validated against 19 heuristic compliance checks and an AI-powered secondary review. Catch issues before they become rejected claims.

19 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_DATAHigh

No GPS coordinates were captured at clock-in or clock-out.

GPS_OUTSIDE_GEOFENCEHigh

Caregiver GPS location is outside the patient's configured geofence radius.

DURATION_MISMATCHMedium

Actual visit duration differs from scheduled duration beyond the allowed threshold.

UNREALISTIC_DURATIONHigh

Visit duration is implausibly long (e.g., over 16 hours) or excessively short.

NO_CAREGIVER_SIGNATUREHigh

Caregiver did not provide their electronic signature at clock-out.

NO_PATIENT_SIGNATUREHigh

Patient or designee signature was not captured when required by state.

NO_MEDICAID_IDHigh

Patient is missing a Medicaid ID required for Medicaid-funded visits.

NO_SERVICE_CODEHigh

No service/procedure code is assigned to the visit.

NO_AUTH_NUMBERMedium

Visit requires a prior authorization number but none is on file.

AUTH_VISITS_EXHAUSTEDHigh

The patient's authorized visit count has been fully used.

ZERO_DURATIONHigh

Clock-in and clock-out timestamps are identical, resulting in zero duration.

FUTURE_TIMESTAMPHigh

Clock-in or clock-out timestamp is in the future relative to server time.

CAREGIVER_MISSING_CREDENTIALSMedium

Caregiver is missing required certifications or credentials for the service type.

NO_MEMBER_VERIFICATIONHigh

No member verification method (signature, PIN, or voice) was completed.

OVERLAPPING_VISITSHigh

This visit overlaps in time with another visit by the same caregiver.

NO_EXCEPTION_CODEMedium

Visit has a flagged issue but no exception code was provided.

NO_REASON_CODEMedium

Visit has an exception code but no reason code explaining the exception.

NO_TASK_DOCUMENTATIONMedium

No tasks were documented for the visit from the patient's care plan.

NO_GPS_CONSENTHigh

Caregiver 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)
Confidence scoring: Each visit receives a confidence score from 0 to 100. Visits below the configurable threshold (default: 70) are automatically flagged for human review.

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.

Pending
Validated
Flagged
Overridden
Exported
Pending

Visit has been clocked out but not yet run through validation checks.

Validated

Visit passed all 19 compliance checks and AI validation. Ready for export.

Flagged

One or more compliance checks failed. Requires admin review before export.

Overridden

Admin reviewed and approved despite flagged issues. Override reason documented.

Exported

Visit data has been exported to the state aggregator in the selected format.

Branching paths: Flagged visits can either be overridden by an admin (moving to Overridden) or corrected by the caregiver and re-validated (moving back to Validated). Both paths lead to Exported once ready.

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.
