What is the role of the EOB/RA in the billing process?

• A. To identify line items that were paid, reduced, or denied.
• B. To schedule future appointments.
• C. To request prior authorization.
• D. To calculate patient liability.

Answer: (A)

The main idea is that an Explanation of Benefits or Remittance Advice is the payer’s record of how each billed service was processed, showing the outcome for every line item. It identifies which items were paid, which were reduced by adjustments, and which were denied, along with the amounts and any reasons for the adjustments or denial. This per-item detail lets you post payments correctly to patient and insurer accounts, determine the remaining patient responsibility, and generate accurate patient statements or support appeals if needed. While patient liability may appear on the EOB/RA, the document’s primary function is to convey the status and rationale for each service, not to schedule appointments or to request prior authorization.
