Federal EVV requirements mean every Medicaid visit must be electronically verified — caregiver identity, patient identity, location, start and end time. When the record doesn't match, the claim can't go out clean. Jackie in Georgia uses HHAeXchange because her MCOs require it. Denise uses the same in Texas. Each manages exceptions manually — which means the ones that don't get resolved before the billing deadline become visits that were delivered and cannot be billed. For Tasha, who is choosing her first EVV system: this is why the exception management layer matters as much as the EVV system itself.
