Prior Authorizations & Predeterminations


Refer to the COVID-19 Preparedness page for temporary information related to servicing members in response to COVID-19.

Health care providers may need to request prior approval in advance of medical, mental health/substance abuse and pharmacy health care services for our member/participants.

What is Prior Authorization

Prior Authorization, preauthorization, prospective review, prenotification or prior approval refer to the prior assessment that proposed services are medically necessary, appropriate and a covered medical expense of the member/participant contract.

A prior authorization is not a guarantee of benefits or payment. Actual availability of benefits is always subject to other requirements of the Plan, such as limitations and exclusions, payment of premium, and eligibility at the time services are provided. The applicable terms of a member/participant’s plan control the benefits that are available. At the time the claims are submitted, they will be reviewed in accordance with the terms of the Contract.

Many of our groups utilize Health Advocacy Solutions and Wellbeing Management Programs for the services that require prior authorization.

Responsibility for Prior Authorization

Usually, health care providers are responsible to request prior authorization before they perform a service. However, a member/participant’s plan may also require them to obtain prior authorization for certain services.

If prior approval is not obtained the costs may not be covered by BCBSTX, billed to the patient and/or the patient’s cost-share may be impacted. If a service or medication is not authorized and the health care provider is out-of-network, the patient will likely pay more out of pocket. The applicable terms of a their plan control the benefits that are available.

What is a Predetermination of Benefits

A predetermination of benefits is a written request for verification of benefits before rendering services. Learn more about Predetermination of Benefits Requests.

Eligibility and Benefits Reminder

Health care providers must obtain eligibility and benefits through Availity® or a preferred vendor first to confirm membership, check coverage, determine if you are in-network for the member/participant's policy, determine whether prior authorization is required and where to submit the request.
