What does an Explanation of Benefits (EOB) detail?

An Explanation of Benefits (EOB) is a document provided by health insurance companies that outlines the specifics of a patient's claims for healthcare services. Specifically, it includes essential information such as what portion of the costs are covered by the insurance provider, the total charges for the services provided, the amount that the insurer has paid, and any remaining balance that the patient is responsible for. This clarity helps patients understand their financial responsibilities regarding their medical bills and what the insurance company has adjudicated.

In contrast, other options describe different aspects of healthcare but do not accurately define the purpose of an EOB. For example, a patient's medical history is contained in their medical records, and the terms of service relate more to the procedural agreements between the patient and provider than to insurance coverage decisions. The procedure for filing an appeal pertains to the process of disputing a claim and is not typically included in the EOB itself. Thus, the correct answer reflects the comprehensive coverage details and the payment decisions made by the insurer, which are fundamental aspects of the EOB.
