Which of the following describes a "covered service"?

A "covered service" refers to any healthcare service that is included under an insurance policy’s benefits. This means that when a patient receives a service that is deemed "covered" by their insurance, the cost of that service is eligible for reimbursement or payment by the insurance company, in accordance with the terms of the policy. These services are typically specified in the policy documentation and may include various types of medical care, preventive services, or treatments depending on the specific coverage offered by the insurer.

In contrast, services that are excluded from an insurance policy are simply not covered at all, meaning the patient would be responsible for all costs associated with those services. Services provided to uninsured patients don't fall under the terms of any insurance agreement, and while prior authorization is a common requirement for certain procedures to be eligible for coverage, it does not define what a covered service is; rather, it establishes conditions that must be met for coverage to apply.
