Hidden overpayment
The invoice said $0 due. The patient was owed $550.72.
A paid invoice looked resolved, but the underlying EOB reconciliation showed the patient had paid more than their actual responsibility on one procedure.

What happened
1
The summary line looked finished
The statement showed a paid balance of $0.00, which usually tells a patient the matter is closed.
2
The line-level match changed the answer
Insured Guard reconciled each procedure against the linked EOB. One side matched cleanly. The other showed payment above the patient responsibility.
3
A refund appeared inside a closed invoice
The system surfaced a $550.72 overpayment and linked the evidence needed to ask the provider for the money back.
A zero balance means you do not owe more. It does not prove you did not overpay.
How do we know
It does not trust the summary balance.
Insured Guard compares what was paid against what each linked EOB says the patient actually owed. When payment runs past responsibility, the gap is still the patient money even if the invoice is silent about it.
