Prior Authorization & Clinical Guidelines

A referral is a written order from your primary care provider (PCP). In some situations, our plan or your PCP must give you a referral for you to get certain medical services from another provider in our plan.

You can get the services listed below without getting a referral from your PCP.

• Emergency care or urgently needed services
• Flu shots, COVID-19 vaccinations, Hepatitis B vaccinations, and pneumonia vaccinations
• Routine women’s health care includes breast exams, screening mammograms (x-rays of the breast), Pap tests, and pelvic exams as long as you get them from an in-network provider.
• In-network Specialist provider office visits do not require a referral, except for pain management services.

You can also get other kinds of care without a referral from your PCP (see Section 2.2 of Chapter 3 in your Evidence of Coverage).

Some medical tests or services require prior authorization before they are scheduled. Your provider requests prior authorization on your behalf. A prior authorization, commonly called a ‘PA’, is not a promise we will cover the cost of the service.

A PA request is a form your provider fills out and sends it to us. Our prior authorization department will review the request and make a decision. A decision for a standard request is made within 14 calendar days and a decision for an expedited request is made within 3 calendar days. You and your provider will be notified if the service is approved or denied.
