Which of the following best describes how pre-admission certifications are used?

Pre-admission certifications are primarily intended to evaluate the necessity of a proposed hospitalization before it occurs. This process helps ensure that insurance providers are only covering medically necessary treatments and services, thereby preventing the occurrence of non-essential medical costs. By confirming that a hospital admission is required based on medical need, pre-admission certification serves as a cost-control measure for both insurers and healthcare providers. It acts as a gatekeeping mechanism, ensuring that patients only receive hospital services when they are deemed necessary for their medical condition. This helps maintain the sustainability of health insurance plans by reducing unnecessary expenses associated with unnecessary admissions.
