Explanation of Payment explained
An EOP is the provider-facing summary of how claims were paid, delivered on paper or as an electronic 835. It typically covers multiple claims in a single payment and lists provider-level adjustments, such as recoupments, separately from claim lines.
Paper EOPs require manual posting and are a common source of posting errors. Enrolling every payer for 835 remittance and EFT removes most of them.
Where Explanation of Payment fits in the revenue cycle
Explanation of Payment sits within the back end of the revenue cycle, after the payer has paid. It is part of payment posting and reconciliation, accurately recording remittances and balancing them against expected payment.
Explanation of Payment is also referred to as EOP. You'll encounter it on payer communications, billing reports, and in conversations between front-office, coding, and accounts-receivable teams.
