What is the term for an abstract of all recent claims filed on each patient, used by the payer to determine concurrent care for the same condition by multiple providers?

The term that refers to an abstract of all recent claims filed on each patient, which is utilized by the payer to determine concurrent care for the same condition by multiple providers, is accurately identified as a common data file. This document consolidates claim information that allows payers to review and analyze the care being provided across different providers for the same patient condition. By having access to this data, insurance providers can ensure proper oversight and prevent issues such as duplicate billing or unnecessary treatments, as it provides a comprehensive view of the patient's treatment history and ongoing care.

The other options don't fit this definition. Remittance advice typically provides details about payments made and reasons for adjustments rather than a summary of claims. An encounter form serves as a tool for healthcare providers to document patient visits and bill for services rendered at a single encounter. A patient ledger keeps a detailed record of all financial transactions and payments related to a patient's care but does not serve the specific function of summarizing claims for multiple concurrent treatments. Therefore, the correct answer aligns with the function of tracking and reviewing all claims related to a patient for coordinating care effectively.
