What happened
1
The invoice listed two identical services
The statement showed the same lab description, service date, provider, and charge amount twice.
2
The EOB did not support two patient charges
The linked EOB did not show a separate patient responsibility that justified both repeated invoice lines.
3
The duplicate candidate was isolated
Insured Guard flagged one $84 line as a likely duplicate so the patient could challenge the repeated charge.
Duplicate lines hide in plain sight because each one looks ordinary by itself.
How do we know
It compares line items against each other and the EOB.
The app groups invoice and EOB lines by date, provider, code or description, and amount. When two lines match too closely without matching support from the EOB, the repeated charge is surfaced.
