Prior authorizations FAQs

Why is a prior authorization needed?

Prior authorization is applied to certain services that may be experimental, not always medically necessary, or over utilized. The purpose of prior authorization is to make sure you receive services that are medically and clinical necessary, and that the services are appropriate for your condition or diagnosis.

What is the prior authorization process?

There are two parts to the prior authorization process:

  1. Your provider submits a request to Priority Health in the electronic authorization portal. The request includes the specific diagnosis and treatment codes for review, along with medical or clinical records to support the request.
  2. Priority Health reviews clinical documentation submitted with the request using appropriate coverage documents and/or criteria to make a decision.  If the service is determined to be a covered benefit and medical necessity criteria is met, the request is approved. If not, the request is reviewed by a Medical Director for a decision. Your provider is notified of the decision in the electronic authorization portal.

Notice of approval is sent to all Medicare members, out-of-network members and those going through a reversed decision (a prior authorization that was previously denied). All members will receive a denial letter, with appeal rights, if the service is denied. If you have any questions about your authorization, contact customer service.

What criteria does Priority Health use for medical necessity reviews?

Priority Health uses written criteria to assist in the evaluation of medical necessity and appropriateness of care. This includes:

How long does it take to get a prior authorization?

Once your provider submits the request for pre-approval to Priority Health, it takes less than14 days to be reviewed. Notice of approval or denial is sent to your health care provider through the electronic authorization portal. If you want to check on the status of your authorization, contact your health care provider or call the Customer Service contact number on the back of your Priority Health member ID card.

Why was my authorization denied?

When a prior authorization request does not meet medical necessity criteria, it is reviewed by a Medical Director and may be denied. A request may also be denied if it is a non-covered or excluded service. If the requested service is denied, your provider will be notified and you will receive a denial letter with the criteria used for review, reason for denial, and your appeal rights.
