A referral is a request for an appointment from your primary care provider (PCP) to a specialist. A specialist is a professional who focuses on a specific disease or part of the body such as:

• Cardiologists who care for patients with heart problems

• Oncologists who care for patients with cancer

• Physical therapists who care for patients for joint or muscle problems

When do I need a referral?

• If you have an HMO plan, you'll need a referral from your PCP to see a specialist.

When do I not need a referral?

• If you have a FPO plan

• To receive emergency or urgent care

How does a referral work?

Referrals are often initiated during a visit with your PCP. You can also contact your provider to request a referral. Your provider will then send a referral to the specialist's office with relevant medical information.

Referrals may take a few days to be processed. The best way to know the status of your referral is to call your provider's office. Ask for the phone number of the specialist so you can call to make an appointment.

What if the specialist I'm referred to is booked?

Your provider may refer you to a specialist that has a very busy schedule. In this case, call Customer Service. We can help you find appointments with other specialists to get you care sooner.

Prior authorization is a request for pre-approval of certain tests, procedures, medical equipment, and medications ordered for you. Your provider must get that approval from Blue Shield before they proceed.

The Blue Shield team will review the prior authorization request to ensure that Medicare covers everything and that the care meets the best available clinical research.

Without this pre-approval, Blue Shield may not pay for your medication or medical procedure. You will then have to pay out of pocket.

Who starts the prior authorization process?

Typically, your provider starts the process by submitting a request on your behalf. It will include details about your diagnosis and why the test, procedure, equipment, or medication is needed. Prior authorizations usually take l to 3 days.

To know if your prior authorization has been processed, you have two options:

• Log in to your account. Under the "myblueshield" dropdown menu, select "Prior authorization." Here you can see a list of all prior authorization requests, as well as those that Blue Shield has approved.

• Call Customer Service. They can help determine the status of your prior authorization. They can also help move the prior authorization along faster.

What if my prior authorization is denied?

You have the right to appeal if Blue Shield denies your prior authorization request.
