What document might be provided to patients as a summary of their financial obligations after insurance payments are processed?

The correct choice is the Provider Remittance Notice. This document serves as a detailed summary of the claims processed for a patient, outlining what the insurance has paid and what the patient is still responsible for covering. It provides critical information, such as the dates of service, procedures performed, amounts billed, payments made by the insurer, and any adjustments that may apply.

This notice is crucial for helping patients understand their financial obligations following the insurance payment processing. It also acts as a communication tool between the healthcare provider and the patient, clarifying the final amounts due.

The other documents mentioned serve different purposes. Open Claims typically refer to claims that have not yet been resolved or paid, rather than summarizing patient obligations. Electronic Remittance Advice, while similar, generally pertains to the electronic format used primarily for providers to receive information about the payment status of claims from insurers, often lacking the patient-focused perspective that the Provider Remittance Notice provides. The term Source Document refers to original documentation such as patient records or invoices used to create claims, not a summary of obligations post-insurance processing.
