Preauthorization Requirements

What is preauthorization?

Preauthorization is the determination of the medical necessity and appropriateness of treatment as a required part of the Utilization Management process for certain covered services. Failure to obtain these proper permissions may affect claim payment, subject to the terms and conditions of a Coverage Plan. A Preauthorization is not a guarantee of benefits or payment.

Services which may require preauthorization:
Inpatient admissions (scheduled and/or non emergent), certain outpatient services, emergent admissions/obstetric, requests for extensions and Plan65 Members when their Medicare Part A benefits have been exhausted.

Other services may also require preauthorization. Please refer to the number on the back of the member’s ID card to obtain Preauthorization requirements.
