When is it typically necessary for a member to obtain prior authorization?

Prior authorization is typically necessary before a member can receive certain high-cost services. This process is crucial because it allows insurance plans, including Anthem Medicare Advantage, to evaluate the medical necessity and appropriateness of a proposed service or treatment before it is provided. High-cost services often involve significant expenses, and obtaining prior authorization helps ensure that these services are warranted based on clinical guidelines and the member’s covered benefits.

In contrast, requiring prior authorization for every procedure is impractical, as many routine or low-cost services do not necessitate this step. Preventive services often have specific coverage rules that do not typically require prior authorization, as they are aimed at maintaining health rather than addressing existing health issues. Emergency treatment is usually exempt from prior authorization requirements so that immediate care can be administered without delay, reflecting the urgent nature of such situations. Thus, the need for prior authorization primarily applies to high-cost services to manage costs and ensure effective care.
