What is one reason a patient may require preauthorization for a procedure?

A patient may require preauthorization for a procedure primarily to ensure insurance coverage. Preauthorization is a process used by insurance companies to determine whether a procedure or service is medically necessary and covered under the patient's health insurance plan. This step is essential because it helps prevent unexpected medical expenses for the patient, ensuring that they will not be held financially responsible for procedures that the insurer has not approved.

The importance of preauthorization lies in its role as a safeguard for both the patient and the insurance provider, facilitating financial planning and reducing potential disputes regarding payment after the service has been rendered. Obtaining this prior approval can significantly impact whether the patient can proceed with the desired medical procedure without incurring out-of-pocket costs.
