Which of the following is used to provide detailed information about a claim's payment?

The remittance advice is used to provide detailed information about a claim's payment because it outlines how the claim was processed and any amounts that were paid, denied, or adjusted. It offers specific details regarding the services rendered, billing codes, patient information, the amount billed, the amount allowed by the insurance, and the actual payment made to the provider. This document is essential for providers to understand the contractual obligations of their agreements with insurance payers, manage patient accounts accurately, and resolve any discrepancies related to payments.

In contrast, a claims register is primarily a tracking tool that helps organize and monitor submitted claims but does not provide detailed payment information. A patient statement reflects the amount owed by the patient and is typically a summary of their account rather than a detailed breakdown of claims and payments. A billing summary offers an overview of the billing activity but lacks the specificity regarding payment processing found in remittance advice.
