Which action is necessary when preauthorization is not approved?

When preauthorization for a medical procedure is not approved, filing an appeal with additional patient history is a crucial step. The appeal process allows healthcare providers to present further information that may not have been considered during the initial review. This additional data can include details about the patient's medical history, the necessity of the procedure, previous treatments, and potential outcomes, which can help support the case for authorization.

Appealing is often necessary because insurance companies have specific criteria that must be met for approval, and further evidence can highlight the urgency or importance of the procedure. By advocating for the patient in this way, the healthcare provider seeks to ensure that the patient receives the needed care without bearing an undue financial burden.

In contrast, canceling the appointment or scheduling a different procedure hinders patient care and does not address the insurance company's decision. Changing the patient’s insurance plan is usually not feasible in a timely manner, and thus it does not serve as an immediate or practical solution to an authorization issue.
